The Tornado GR4 is a variable geometry, two-seat, day or night, all-weather attack aircraft, capable of delivering a wide variety of weapons. Powered by two Rolls-Royce RB 199 Mk 103 turbofan engines, the GR4 is capable of low-level supersonic flight and can sustain a high subsonic cruise speed. The aircraft can fly automatically at low level using terrain-following radar when poor weather prevents visual flight. The aircraft is also equipped with forward-looking infrared and is night-vision goggle compatible, making it a capable platform for passive night operations. For navigation purposes, the Tornado is equipped with an integrated global positioning inertial navigation system that can also be updated with visual or radar inputs. The GR4 is also equipped with a Laser Ranger and Marked Target Seeker system that can be used for ground designation or can provide accurate range information on ground targets.

 

The GR4 can carry up to three Paveway II, two Paveway III or Enhanced Paveway Laser and Global Positioning System Guided Bombs (LGBs), and by using a Thermal Imaging Airborne Laser Designation (TIALD) pod it is able to self-designate targets for LGB delivery. The GR4 also has a ground-mapping radar to identify targets for the delivery of conventional 1000lb bombs. All GR4 aircraft are capable of carrying the Air Launched Anti- Radiation Missile (ALARM), which homes on the emitted radiation of enemy radar systems and can be used for the suppression of enemy air defences. The GR4 is capable of carrying up to nine ALARM missiles or a mixed configuration of ALARM missiles and bombs. In the reconnaissance role the GR4 can carry the Digital Joint Reconnaissance Pod to provide detailed reconnaissance imagery; this is currently being replaced with the RAPTOR pod, which provides an even greater day-and night reconnaissance potential.

 

For self-protection, the GR4 is normally armed with two AIM-9L Sidewinder short-range air-to-air missiles, a BOZ-107 Pod on the right wing to dispense chaff and flares and a Sky Shadow-2 electronic countermeasures pod on the left wing. The aircraft can also carry an integral 27mm Mauser cannon capable of firing 1700 rounds per minute.

 

The Tornado GR4 is now equipped with the Storm Shadow missile and the new Brimstone missile. The Storm Shadow allows the Tornado to make precision strikes in poor weather with a greatly increased stand-off range from the target area. Brimstone provides the Tornado with an effective anti-armour weapon, also providing an enhanced stand-off range.

 

The Tornado GR4 is currently operated from two bases. Based at RAF Lossiemouth, in Scotland, are the Operational Conversion Unit, No. 15(R) Squadron, and Nos 12(B), 14 and 617 Squadrons. RAF Marham is the home of the GR4s of Nos II(AC), IX(B), 13 and 31 Squadrons.

 

In addition to its long-range, high-speed precision strike capability, including supersonic at low level with a low-level combat radius of 400nmls, the Tornado GR4 is a world leader in the specialised field of all-weather, day and night tactical reconnaissance. The new RAPTOR (Reconnaissance Airborne Pod TORnado) pod is one of the most advanced reconnaissance sensors in the world and greatly increased the effectiveness of the aircraft in the reconnaissance role. Its introduction into service gave the GR4 the ability to download real-time, long-range, oblique-photography data to ground stations or to the cockpit during a mission. The stand-off range of the sensors also allows the aircraft to remain outside heavily defended areas, thus minimising the aircraft’s exposure to enemy air-defence systems.

 

The Tornado Ground Reconnaissance Force (TGRF) has been at the forefront of UK Military Deployed Operations continuously for the last 20 years. The Force provides vital protection when our troops are engaged by enemy ground forces and have the ability to strike important targets. We may not know individual soldiers and marines personally, but we deeply care about them and salute their courage and achievements; we do everything in our power to protect them. The last 12 months have been a particularly busy period, seeing concurrent operations in Afghanistan and Libya, integrating with our allied armed forces from around the world.

 

The Role Demonstration Team are very proud to represent the Royal Air Force and specifically the TGRF by demonstrating some realistic scenarios encountered on deployed operations, enabling you, the public, to gain a better understanding of their core task. However, when you see them performing, it will be the culmination of weeks of preparation and concerted effort by not only the crews, but a dedicated team of managerial, engineering and administrative support back at RAF Lossiemouth. Whilst the crews take the glory for the superb displays, they cannot even begin to do their job without the commitment and backing of these dedicated professionals.

 

With advances in bomber technology, the US Army Air Corps in 1937 began to wonder if its current fighters were inadequate to defend the nation from attack. The USAAC, on the advice of Lieutenant Benjamin Kelsey, issued Proposal X-608/609, calling for an interceptor equipped with tricycle landing gear and the Allison V-1710 inline engine, heavy cannon armament, and capable of 360 mph and a ceiling of above 20,000 feet, which it had to reach within six minutes.

 

The proposal was a tough one, and after several discarded designs, Lockheed designer Clarence “Kelly” Johnson settled on an unusual planform: two engines extending back to twin tails, joined by the wings and tailplane, with the pilot and armament concentrated in a central “gondola” fuselage. The reason for the tail “booms” was that the aircraft needed superchargers, and the only place to put them was behind the engines. The design itself posed a number of problems, namely engine torque: twin-engined propeller aircraft tend to pull heavily in the direction of the torque. Johnson solved this by having the propellers counter-rotate away from each other, canceling the torque between them. Putting all the guns along a central axis in front of the pilot also made shooting more accurate and easier to figure out. Flush rivets and stainless steel construction gave the aircraft a smooth finish and better speed.

 

The first XP-38 Lightning flew in January 1939. To prove the fighter’s usefulness to a skeptical USAAC, the XP-38 was flown cross-country from Lockheed’s plant at Burbank, California, to New York City. It crashed due to engine icing just short of New York, but it made the trip in just over seven hours at a sustained speed of 399 mph.

 

Impressed, the USAAC ordered 13 YP-38 pre-production aircraft, but these were delayed by Lockheed already being at maximum production, with the result that the first YP-38 did not reach the now-US Army Air Force until June 1941. It had already been ordered by the Royal Air Force, but now a new problem arose: the P-38 was too hot an aircraft. In dives, it had been found that the P-38 would quickly enter compressibility and keep accelerating until it hit the ground, due to the air over the wings becoming supersonic while the aircraft remained subsonic. Frantic efforts by Lockheed to end the problem failed, and despite the introduction of dive brakes on later aircraft, the P-38 was never cured of this problem.

 

The British only held to their order of 143 aircraft after legal action by Lockheed—making matters worse was that RAF aircraft were delivered without counter-rotating propellers or superchargers, making them difficult to control and at a severe disadvantage above 15,000 feet. Lack of adequate cockpit heating meant that the pilot risked hypothermia during the cold European winters. The RAF had named the aircraft “Lightning” for its performance, but loathed the fighter and were all too happy to return them to Lockheed. The P-38, which had finally entered production as the P-38D Lightning, had acquired a bad reputation that it would never wholly shed.

 

Despite its misgivings, the USAAF continued the Lightning in production, because whatever the aircraft’s other problems, it could not be matched in speed or range. Deployed to Iceland and the Aleutian Islands, P-38s scored the first American kill of the European theater on 14 August 1942; it had already scored its first kills, over the Aleutians, a week before. Deployed to North Africa to cover the Torch landings and operations in Tunisia, the heavy armament, speed, range, and surprising ease of flying, the Lightning earned the nicknamed Gabelschwanzteufel (Fork-Tailed Devil) from its German opponents.

 

Unfortunately, the Germans soon discovered the P-38’s weakness—it still was a poor performer above 15,000 feet, it had a very slow roll rate, and lethal blind spots. It was liked by its pilots, who pointed out that it was the only long-range escort then available, and the only one that could lose an engine and stay in the air, but its poor reputation persisted. Even after further combat proved its worth and improvements by Lockheed resulted in the P-38J, the 8th Air Force began relegating its P-38s to ground attack duties in favor of the P-51. It remained in Europe until war’s end, operating as attack aircraft and F-5 reconnaissance aircraft; a few were further modified with a bombardier position in a clear nose as pathfinders, the so-called “Droopsnoot.” Despite its reputation, European Lightnings produced a number of aces, including Robin Olds; French author and aviation pioneer Antoine de Saint-Exupery was killed during a P-38 reconnaissance mission in 1944.

 

In the Pacific, however, the P-38 excelled. The USAAF lacked any sort of long-range fighter, and the P-38 allowed safer operations over water and distance. This led to it being chosen to shoot down Admiral Isoroku Yamamoto in 1943, as it was the only fighter that could make the trip from Guadalcanal to Bougainville. General George Kenney, commanding the 15th Air Force, asked for all the P-38s Lockheed could supply. While it was no dogfighter, especially with the nimble Japanese fighters, it could snap turn with an A6M Zero, it was better in the vertical than Japanese aircraft, and its heavy armament would obliterate any enemy that got in front of it. Whereas P-38 pilots in Europe froze, the lack of air conditioning in the Pacific meant that P-38 pilots there flew in only shorts, tennis shoes, and flight helmet. The P-38’s lack of high altitude performance was not a problem in the Pacific, where most air combat took place at low level. Over 100 men would become aces in the Lightning, including Richard Bong, Thomas McGuire, and Charles McDonald; with 1800 confirmed victories, the P-38 was the most successful USAAF fighter in the Pacific.

 

After the end of World War II, jet fighters spelled the end of the P-38. Though it would persist in Italian Air Force service until 1956, and was used by Nationalist China and some Central American nations, nearly all had been scrapped by the mid-1950s. Of 10,037 Lightnings produced, today only 24 aircraft survive, with half flyable.

 

This P-38L, 44-53186, was built as a F-5G tactical reconnaissance aircraft in 1944. After the war, it was declared surplus and and bought by an aerial survey company, retaining its camera nose. It flew until 1963; in 1967, it was bought by Harrah's, restored with a gun nose, and placed on display. It was subsequently bought by a warbird collector in 1982, and restored to flyable status. Evergreen bought the aircraft in 1990, and it was placed on display at the Evergreen Air Museum in 2006. It was rumored to be up for sale in 2014, but was still on display when I visited the museum in 2015.

 

Because of the way it is placed, it was difficult to get a good picture, so I chose this head-on portrait of the P-38. This would not be something you would want to see coming in behind you. 44-53186 is displayed in the colors of the 49th Fighter Group, based at Tacloban in the Philippines in 1944; both Dick Bong and Thomas McGuire flew in the 49th.

The world’s top female surfers proved by pairing up grace, strength and talent, that they are capable of taking the sport to new heights.

 

The 2nd SWATCH GIRLS PRO France 2011 in Hossegor delivered a firework of spectacular surfing! Moving through the rounds, the ladies faced strong currents and fast crashing waves. Heat after heat they tackled the rough challenge by laying down outstanding performances with technical, smooth and stylish surfing. Unfortunately last year’s winner and 4-time World Champion Stephanie Gilmore (AUS) and top favourite Coco Ho (HAW) were already eliminated in the early rounds.

 

In the end Sally Fitzgibbons (AUS) defeated Sage Erickson (USA) on an epic final day of competition to win the SWATCH GIRLS PRO France at Seignosse in Hossegor.

 

Both Fitzgibbons and Erickson surfed at their limit on the final day of competition in front of the packed holiday crowd who flocked to the beach to support some of the world’s finest women’s surfers, but it was Fitzgibbons who found the scores needed to take the victory over the American surfer.

 

Fitzgibbons, who is currently rated No. 2 on the elite ASP Women’s World Title Series, competed in her second consecutive SWATCH GIRLS PRO France event and her victory marks her third major ASP win this year.

 

Erickson was impressive throughout the entire competition, eventually defeating Sarah Baum (ZAF) in the Semifinals, but was unable to surpass Fitzgibbons for the win.

 

Sarah Mason Wins 2-Star Swatch Girls Pro Junior France

 

Sarah Mason (Gisbourne, NZL) 16, today took out the ASP 2-Star Swatch Girls Pro Junior France over Dimity Stoyle (Sunshine Coast QLD, AUS) 19, it a closely contested 35-minute final that went down to the wire in tricky 3ft (1m) waves at Les Bourdaines.

 

Europe’s finest under-21 athletes faced some of the world’s best up-and-comers in the Swatch Girls Pro Junior France in their attempt to qualify for the ASP World Junior Series which starts October 3, in Bali, Indonesia.

 

Mason, who impressed the entire event with her precise and stylish forehand attack, left little to chance in the 35-minute final getting off to a quick start to open her account and then built on her two-wave total to claim victory with 11.73 out of 20. The quietly spoken goofy-footer was a standout performer in the ASP 6-Star Swatch Girls Pro France and backed it up with a commanding performance against her fellow Pro Junior members.

 

“It is amazing. I am so happy and it is one of my best results for sure. It was tricky to try and pick the good ones but I picked a couple so it was great. All the girls are definitely ripping so you have to step up the level to get through your heats so I am stoked with the win. It has been super fun and I have enjoyed the entire event so to win is just amazing.”

 

Dimity Stoyle was unable to bridge the gap over her opponent in the final finishing second despite holding priority several times in the later stages of the encounter. The Swatch Girls Pro Junior France has proved the perfect training ground for Stoyle to continue with her excellent results already obtained this season on the ASP Australasia Pro Junior series where she is currently ranked nº2.

 

“I am still happy with second and I really wanted to win here but I tried my best. This is the best event I have been in so far it is really good the set up, the waves and everyone loves it. I can’t believe how good the French crowd are. They love surfing and they love us all so I am definitely going to come back.”

 

Felicity Palmateer (Perth WA, AUS) 18, ranked nº9 on the ASP Women’s Star Tour, finished equal 3rd in a low scoring tactical heat against Stoyle where positioning and priority tactics towards the final part played a major role as the frequency of set waves dropped.

 

“When I first paddled out I thought it was breaking more out the back but as the tide started to change it moved in and became a little inconsistent. At the start of the heat there were heaps of waves but then it went slow and priority came into play and I kept trying to get one. I am not really fussed because I am travelling with Dimity (Stoyle) and stoked that she has made the final.”

 

Palmateer has used the Swatch Girls Pro Junior France as a building block towards her ultimate goal of being full-time on the ASP Women’s World Tour. Her objectives are clear and 2011 is an extremely important year.

 

“I would love to get a World Junior title but at the moment my goal is to qualify for the World Tour through the Star events. If I can get more practice without that much pressure on me like this year and then if I qualify it will be even better for 2012.”

 

Bianca Buitendag (ZAF) 17, placed 3rd in the Swatch Girls Pro Junior France after failing to oust eventual event winner Sarah Mason in semi-final nº1. Buitendag looked dangerous throughout the final day of competition and was unlucky not to find any quality scoring waves in a slow heat. Trailing for the majority of the encounter, Buitendag secured her best ride in the final moments which proved not enough to advance.

 

“The swell definitely dropped and although the conditions were quite nice I didn’t get any good scoring waves. I have a Pro Junior event coming up in South Africa and it is very important to get a result there to qualify for the World Juniors.”

 

Maud Le Car (St Martin, FRA) 19, claimed the best result of the European contingent finishing equal 5th to jump to nº1 position on the ASP Women’s European Pro Junior series. Le Car led a low scoring quarter-final bout against Bianca Buitendag until losing priority in a tactical error which allowed her opponent to sneak under her guard and claim the modest score required to win.

 

“I didn’t surf really well in that heat and I am a little bit disappointed because it is for the selection to the World Juniors with the other European girls. The waves were not the best and it was difficult to catch some good waves and unfortunately I didn’t make it. It is really good to be at the top but I have some other contests to improve and to do some good results and to make it to the World Juniors.”

 

The Swatch Time to Tear Expression Session was won by the team composed of Swatch Girls Pro France finalists Sally Fitzgibbons (AUS), Sage Erickson (USA) and equal 3rd placed Courtney Conlogue (USA) in a dynamic display of modern progressive surfing in the punchy 3ft peaks in front of a packed surf hungry audience lining the shore.

Details

 

Typhoon provides the RAF with a multi-role combat aircraft, capable of being deployed in the full spectrum of air operations, from air policing, to peace support, through to high intensity conflict. It is currently employed on permanent ops in the Falkland Islands, UK QRA North and UK QRA South.

 

Britain, Germany, Italy and Spain formally agreed to start development of the aircraft in 1988 with contracts for a first batch of 148 aircraft – of which 53 were for the RAF – signed ten years later. Deliveries to the RAF started in 2003 to 17(R) Sqn who were based at BAE Systems Warton Aerodrome in Lancashire (alongside the factory where the aircraft were assembled) while detailed development and testing of the aircraft was carried out. Formal activation of the first Typhoon Squadron at RAF Coningsby occurred on the 1st Jul 2005. The aircraft took over responsibility for UK QRA on 29 Jun 2007 and was formally declared as an advanced Air Defence platform on 1 Jan 2008.

 

Initial production aircraft of the F2 Tranche 1 standard were capable of air-to-air roles only and were the first Typhoons to hold UK QRA duties. In order to fulfill a potential requirement for Typhoon to deploy to Op HERRICK, urgent single-nation work was conducted on Tranche 1 to develop an air-to-ground capability in 2008. Tranche 1 aircraft were declared as multi-role in Jul 2008, gaining the designation FGR4 (T3 2-seat variant), fielding the Litening Laser Designator Pod and Paveway 2, Enhanced Paveway 2 and 1000lb freefall class of weapons. Only a handful of F2/T1 aircraft remain, these will be upgraded to FGR4/T3 by the end of 2012. Tranche 2 aircraft deliveries commenced under the 4-nation contract in 2008, in the air-to-air role only. These aircraft were deployed to the Falkland Islands to take-over duties from the Tornado F3 in Sep 09. Currently, upgrades to Tranche 2 continue as part of the main contract, with air-to-ground capability expected in 2012.

 

A total of 53 Tranche 1 aircraft were delivered, with Tranche 2 contract provisioning for 91 aircraft. 24 of these were diverted to fulfill the RSAF export campaign, leaving 67 Tranche 2 aircraft due for delivery to the RAF. The Tranche 3 contract has been signed and will deliver 40 aircraft. With the Tranche 1 aircraft fleet due to retire over the period 2015-18, this will leave 107 Typhoon aircraft in RAF service until 2030.

 

Future weapons integration will include Meteor air-to-air missile, Paveway IV, Storm Shadow, Brimstone and Small Diameter Bomb. Additionally, it is intended to upgrade the radar to an Active Electronically Scanned Array.

Random thoughts

 

A great patriot, genius, humble, highly capable, thorough gentleman, Aftab Ghulam Nabi Kazi, left us for his eternal abode recently. He was almost 97. May Allah rest his soul in Jannah – Ameen.

I was very closely associated with Kazi Sahib for many years. In 1975, my wife, our two young daughters and I came to Pakistan just before Christmas on our usual annual holidays. I met Bhutto Sahib after three days, at which meeting his competent MS, Brig Imtiaz (later Ma Gen) was also present. Bhutto asked me to check on the progress of the work being done under Munir Ahmed Khan of the PAEC.

I had given them some hints the year before on how to get started on enrichment. I was shocked to see the casual and lethargic way in which the work was being handled. When I informed Bhutto, he was visibly annoyed. He thought for a few seconds and then requested me not to go back but to help the country face the mortal danger from India after their nuclear test of May 18, 1974.

I was shocked. I had a good job and my wife’s elderly parents were in Holland and she was the only one to look after them. Considering everything and having discussed the matter with my wife, I agreed. My wife returned to Holland alone with the girls, and had the daunting task of informing her parents (her mother was in hospital at the time) and packing up the house. She returned to Pakistan after two months with only some clothes and personal items.

Meanwhile I had been appointed as adviser to the PAEC with a salary of Rs3,000 per month, which I didn’t receive for the first six months. The work couldn’t progress because of incompetence and bureaucracy. In July of that year I wrote to the PAEC chairman asking for an interview, to which I got no reply. Since I had joined he had strongly hinted that we should not work for weapons and that Bhutto was obsessed with making a bomb. When I didn’t receive a reply, I wrote a letter to Bhutto enclosing a copy of my letter to the PAEC chairman. He called me to the Governor House in Lahore immediately, where I met him together with Agha Shahi and Gen Imtiaz and explained my case.

After two days Gen Imtiaz phone that there was a meeting at the Foreign Office. I drove there in my own car as neither car nor driver had been put at my disposal. There I met A G N Kazi, Ghulam Ishaq Khan and Agha Shahi, all secretaries general at the time. After hearing me out they suggested that I take over as chairman of the PAEC. I declined as I felt this would immediately expose our plans to the West. I frankly told them that if the project was not under my control it wouldn’t succeed.

I was asked to return the next day, when I was informed that they had accepted my proposal and that a new organisation (Engineering Research Laboratories – ERL) would be set up. Gen Imtiaz used Shahi Sahib’s green line to inform Bhutto. I spoke to him as well and told him that I needed a free hand.

The next day we had a meeting in Bhutto Sahib’s office. He formed a coordination board with A G N Kazi as chairman and Ghulam Ishaq Khan and Agha Shahi as members. The board was given the powers of a PM. Gen Zia was also there as COAS and he agreed to give me a team of civil engineers. This team was headed by a brigadier, a dashing, handsome go-getter. They never let me down.

Next the problem of determining the powers I needed to rush through the programme was tackled by the brigadier and me. I made four copies of the suggestions and presented it to the board at Kazi Sahib’s office. After glancing at the very first page, G I Khan remarked that I was asking for powers only the PM had. At that Kazi Sahib said: “Ishaq, if you want another PWD, discuss it, otherwise give the powers Dr Khan is asking for. We are there to oversee everything.” With that the matter was closed. It was this approval that enabled our programme to succeed.

Kazi Sahib was a thorough gentleman – soft spoken and very competent. He could instantly grasp the gist of a problem. I was allowed to see him without any prior appointment. I was ably supported by Agha Shahi, who asked his DG Administration – a very competent officer – to issue me a diplomatic passport and to take care of our foreign travel.

On July 5, 1977, Gen Zia staged the coup. Ghulam Ishaq Khan was made secretary general-in-chief, the de facto prime minister, thus, due to his higher rank, automatically becoming chairman of the committee. He offered continued charge of our meetings to Kazi Sahib, but he politely refused.

The late A G N Kazi had a brilliant, chequered career. After high school in Sindh he obtained a double Masters in Physics and Statistics. He was selected for the ICS (together with Agha Shahi and Mian Riazuddin) and worked as DC before Partition.

After Partition he moved to Pakistan and was successively posted as secretary finance, Sindh and adviser to the governor; finance secretary of West Pakistan; economic minister in the Pakistan Embassy in Washington; additional chief secretary Planning and Development, West Pakistan; chairman Wapda (where he supervised the Mangla Dam); secretary Industries & National Resources; federal finance minister and chairman Central Board of Revenue; secretary general finance and economic coordination; adviser to the president on economic affairs; governor of the State Bank of Pakistan and, finally, secretary general finance.

When ERL came into being, he was secretary general finance and what a great support he was to us – a pillar of strength and hope. After he left, Ghulam Ishaq Khan handled the programme superbly. May Allah Almighty grant a high place in Jannah to all who helped us in making Pakistan a nuclear and missile power – Ameen.

***UPDATE*** Tamara and Josh have really been working hard to get their new home up to snuff. They snared this great table for their library sitting area.

The NATO Research Vessel ALLIANCE is one of the most capable undersea research platforms at sea today and possibly the most quietest motor vessel afloat. She is unique in being one of only two ships owned jointly by member nations of the North Atlantic Treaty Organisation. NRV ALLIANCE has the status of a public vessel of the Federal Republic of Germany and flies the German republic flag. The vessel is assigned to the NATO Undersea Research Centre under the Allied Command Transformation, located at La Spezia, Italy.

 

ALLIANCE enables scientists from the Centre to conduct a wide range of experiments in all the oceans of importance to NATO. Particular care has been taken to minimise the noise generated by the ship in order to reduce interference with the environmental measurements and acoustic experiments which form an important basis for Centre research. The vessel has been designed for eight different noise states, the quietest one operating on batteries. An auxiliary gas turbine generator provides the lowest noise propulsion option, leading up to the full complement of diesel electric generators allowing the vessel to tow twenty tonnes at twelve knots. The gas turbine and diesel electric generators are mounted on individual vibration isolating rafts and enclosed within acoustic booths to reduce hull and airborne noise transmission.

 

ALLIANCE has 400 m² of open deck working area as well as 370 m² of enclosed laboratory spaces. There is an additional 500 m³ of scientific storage. The vessel is equipped with an extensive suite of winches and other deck handling gear for deploying and towing systems and instrumentation needed for acoustic and oceanographic research.

During World War II, both Great Britain and Germany had experimented with very large glider designs (the Hamlicar and Gigant, respectively) capable of carrying tanks. Though glider assaults had varying results during the war, the US Air Force briefly considered resurrecting the idea in 1948, and commissioned Chase Aircraft to build a large glider, the XCG-20 Avitruc. The XCG-20 was of all-metal construction, with a fully-equipped flight deck and a rear-mounted loading ramp for vehicles to be driven directly into the fuselage. The USAF abandoned the idea of glider assaults soon after the first XCG-20 was completed, but Chase had anticipated this: through the simple installation of two propeller-driven engines, the XCG-20 became the XC-123. This itself was considered only an interim design, as the XC-123A had four turbojet engines, becoming the first all-jet transport aircraft.

 

The USAF rejected the XC-123A, as it was found to have poor performance and short range, owing to the thirsty jets of the early 1950s. However, the piston-engined XC-123 showed promise, and the USAF ordered it into production in 1953. Production was delayed due to Chase Aircraft being acquired by Kaiser, who in turn sold the design to Fairchild Aircraft, who would produce it as the C-123B Provider.

 

The C-123 was considered a supplemental aircraft to the C-119 Flying Boxcar already in service and the soon-to-be-deployed C-130 Hercules. It had better single-engine performance than the C-119, and acquired a reputation for reliability, rugged design, simple maintenance, and the ability to land almost anywhere. A small number were converted to C-123J standard, with ski landing gear for operations in Antarctica and Greenland, and experiments were even made to convert it to an amphibian. Nevertheless, the number of C-123s in service were small compared to other types, and the C-130 began replacing it beginning in 1958.

 

As the United States involved itself more in the Vietnam War, one major advantage of its Viet Cong and North Vietnamese Army adversaries was the very jungle of Vietnam itself, which provided ready-made cover and camouflage from American air units. In an attempt to deprive the VC/NVA of jungle cover in known concentration areas, the USAF converted a number of C-123s to UC-123 standard, with spraying equipment for the pesticide Agent Orange. Under Operation Ranch Hand, UC-123s were among the first USAF aircraft deployed to Vietnam, and the first USAF aircraft lost in combat was a UC-123B. Spraying Agent Orange was very dangerous work, as it involved flying low and slow over hostile territory; it would not be until after the Vietnam War was over that it was learned that Agent Orange, used in the concentrated quantity employed in Vietnam, was also a deadly carcinogenic.

 

Besides their controversial employment as defoilant sprayers, standard C-123s were used as transports and Candlestick flareships, as the C-130 demand was exceeding supply, and the US Army’s CV-2 (later C-8) Caribous were proving the worth of a short-takeoff and landing transport. To improve the Provider’s performance in the “hot and high” conditions of Vietnam, two J85 turbojets were added beneath the wings of the C-123K variant, which became the final Provider variant and the main type used in Vietnam. CIA-flown Providers were used by Air America to clandestinely supply friendly Hmong tribes in Laos and in Cambodia, while two specialized NC-123K Black Spot aircraft were used to monitor traffic on the Ho Chi Minh Trail, bringing in gunships to engage any targets—though the Black Spots could also carry bombs. 54 C-123s were lost in Vietnam, second only to the C-130.

 

Following the end of American involvement in Vietnam, the C-123Ks were either handed over to South Vietnam or relegated to USAF Reserve and Air National Guard units, from which they were finally withdrawn around 1980. A few UC-123Ks were used to spray insecticides in Alaska and Guam as late as 1982. 11 other air forces used Providers, and the last C-123s were retired from the South Korean Air Force in 2001. 27 are preserved as museum pieces and a few remain in revenue service as “bush” aircraft in Alaska and elsewhere; remaining aircraft in storage were scrapped due to Agent Orange contamination.

 

The C-123K Provider on display in the Malmstrom Museum’s model collection belongs to the 311th Air Commando Squadron, based at Phan Rang, South Vietnam. It carries standard Southeast Asia camouflage of two shades of green and tan over white. This aircraft is that flown by Lieutenant Colonel Joe Jackson on his Medal of Honor mission.

=========================

From Wikipedia: The mourning dove (Zenaida macroura) is a member of the dove family, Columbidae. The bird is also known as the American mourning dove or the rain dove, and erroneously as the turtle dove, and was once known as the Carolina pigeon or Carolina turtledove. It is one of the most abundant and widespread of all North American birds. It is also a leading gamebird, with more than 20 million birds (up to 70 million in some years) shot annually in the U.S., both for sport and for meat. Its ability to sustain its population under such pressure is due to its prolific breeding; in warm areas, one pair may raise up to six broods of two young each in a single year. The wings make an unusual whistling sound upon take-off and landing, a form of sonation. The bird is a strong flier, capable of speeds up to 88 km/h (55 mph).

 

Mourning doves are light grey and brown and generally muted in color. Males and females are similar in appearance. The species is generally monogamous, with two squabs (young) per brood. Both parents incubate and care for the young. Mourning doves eat almost exclusively seeds, but the young are fed crop milk by their parents.

 

Distribution: The mourning dove has a large range of nearly 11,000,000 km2 (4,200,000 sq mi). The species is resident throughout the Greater Antilles, most of Mexico, the Continental United States, southern Canada, and the Atlantic archipelago of Bermuda. Much of the Canadian prairie sees these birds in summer only, and southern Central America sees them in winter only. The species is a vagrant in northern Canada, Alaska, and South America. It has been spotted as an accidental at least seven times in the Western Palearctic with records from the British Isles (5), the Azores (1) and Iceland (1). In 1963, the mourning dove was introduced to Hawaii, and in 1998 there was still a small population in North Kona. The mourning dove also appeared on Socorro Island, off the western coast of Mexico, in 1988, sixteen years after the Socorro dove was extirpated from that island.

 

Description: The mourning dove is a medium-sized, slender dove approximately 31 cm (12 in) in length. Mourning doves weigh 112–170 g (4.0–6.0 oz), usually closer to 128 g (4.5 oz). The elliptical wings are broad, and the head is rounded. Its tail is long and tapered ("macroura" comes from the Greek words for "large" and "tail"). Mourning doves have perching feet, with three toes forward and one reversed. The legs are short and reddish colored. The beak is short and dark, usually a brown-black hue.

 

The plumage is generally light gray-brown and lighter and pinkish below. The wings have black spotting, and the outer tail feathers are white, contrasting with the black inners. Below the eye is a distinctive crescent-shaped area of dark feathers. The eyes are dark, with light skin surrounding them.[6] The adult male has bright purple-pink patches on the neck sides, with light pink coloring reaching the breast. The crown of the adult male is a distinctly bluish-grey color. Females are similar in appearance, but with more brown coloring overall and a little smaller than the male. The iridescent feather patches on the neck above the shoulders are nearly absent, but can be quite vivid on males. Juvenile birds have a scaly appearance, and are generally darker.

 

All five subspecies of the mourning dove look similar and are not easily distinguishable. The nominate subspecies possesses shorter wings, and is darker and more buff-colored than the "average" mourning dove. Z. m. carolinensis has longer wings and toes, a shorter beak, and is darker in color. The western subspecies has longer wings, a longer beak, shorter toes, and is more muted and lighter in color. The Panama mourning dove has shorter wings and legs, a longer beak, and is grayer in color. The Clarion Island subspecies possesses larger feet, a larger beak, and is darker brown in color.

 

Habitat:

The mourning dove occupies a wide variety of open and semi-open habitats, such as urban areas, farms, prairie, grassland, and lightly wooded areas. It avoids swamps and thick forest. The species has adapted well to areas altered by humans. They commonly nest in trees in cities or near farmsteads.

 

Migration:

Most mourning doves migrate along flyways over land. On rare occasions, mourning doves have been seen flying over the Gulf of Mexico, but this appears to be exceptional. Spring migration north runs from March to May. Fall migration south runs from September to November, with immatures moving first, followed by adult females and then by adult males. Migration is usually during the day, in flocks, and at low altitudes. However, not all individuals migrate. Even in Canada some mourning doves remain through winter, sustained by the presence of bird feeders.

 

Sounds:

This species' call is a distinctive, plaintive cooOOoo-woo-woo-woooo, uttered by males to attract females, and may be mistaken for the call of an owl at first. (Close up, a grating or throat-rattling sound may be heard preceding the first coo.) Other sounds include a nest call (cooOOoo) by paired males to attract their mates to the nest sites, a greeting call (a soft ork) by males upon rejoining their mates, and an alarm call (a short roo-oo) by either male or female when threatened. In flight, the wings make a fluttery whistling sound that is hard to hear. The wing whistle is much louder and more noticeable upon take-off and landing.

 

Reproduction: Courtship begins with a noisy flight by the male, followed by a graceful, circular glide with outstretched wings and head down. After landing, the male will approach the female with a puffed-out breast, bobbing head, and loud calls. Mated pairs will often preen each other's feathers.

 

The male then leads the female to potential nest sites, and the female will choose one. The female dove builds the nest. The male will fly about, gather material, and bring it to her. The male will stand on the female's back and give the material to the female, who then builds it into the nest. The nest is constructed of twigs, conifer needles, or grass blades, and is of flimsy construction. Mourning doves will sometimes requisition the unused nests of other mourning doves, other birds, or arboreal mammals such as squirrels.

 

Most nests are in trees, both deciduous and coniferous. Sometimes, they can be found in shrubs, vines, or on artificial constructs like buildings, or hanging flower pots. When there is no suitable elevated object, mourning doves will nest on the ground.

 

The clutch size is almost always two eggs. Occasionally, however, a female will lay her eggs in the nest of another pair, leading to three or four eggs in the nest. The eggs are white, 6.6 ml (0.23 imp fl oz; 0.22 US fl oz), 2.57–2.96 cm (1.01–1.17 in) long, 2.06–2.30 cm (0.81–0.91 in) wide, 6–7 g (0.21–0.25 oz) at laying (5–6% of female body mass). Both sexes incubate, the male from morning to afternoon, and the female the rest of the day and at night. Mourning doves are devoted parents; nests are very rarely left unattended by the adults. When flushed from the nest, an incubating parent may perform a nest-distraction display, or a broken-wing display, fluttering on the ground as if injured, then flying away when the predator approaches it.

 

Incubation takes two weeks. The hatched young, called squabs, are strongly altricial, being helpless at hatching and covered with down. Both parents feed the squabs pigeon's milk (dove's milk) for the first 3–4 days of life. Thereafter, the crop milk is gradually augmented by seeds. Fledging takes place in about 11–15 days, before the squabs are fully grown but after they are capable of digesting adult food. They stay nearby to be fed by their father for up to two weeks after fledging.

 

Mourning doves are prolific breeders. In warmer areas, these birds may raise up to six broods in a season. This fast breeding is essential because mortality is high. Each year, mortality can reach 58% a year for adults and 69% for the young.

 

The mourning dove is monogamous and forms strong pair bonds. Pairs typically reconvene in the same area the following breeding season, and sometimes may remain together throughout the winter. However, lone doves will find new partners if necessary.

 

Ecology: Mourning doves eat almost exclusively seeds, which make up more than 99% of their diet. Rarely, they will eat snails or insects. Mourning doves generally eat enough to fill their crops and then fly away to digest while resting. They often swallow grit such as fine gravel or sand to assist with digestion. The species usually forages on the ground, walking but not hopping. At bird feeders, mourning doves are attracted to one of the largest ranges of seed types of any North American bird, with a preference for canola, corn, millet, safflower, and sunflower seeds. Mourning doves do not dig or scratch for seeds, though they will push aside ground litter; instead they eat what is readily visible. They will sometimes perch on plants and eat from there.

 

Mourning doves show a preference for the seeds of certain species of plant over others. Foods taken in preference to others include pine nuts, sweetgum seeds, and the seeds of pokeberry, amaranth, canary grass, corn, sesame, and wheat. When their favorite foods are absent, mourning doves will eat the seeds of other plants, including buckwheat, rye, goosegrass and smartweed.

 

Mourning doves can be afflicted with several different parasites and diseases, including tapeworms, nematodes, mites, and lice. The mouth-dwelling parasite Trichomonas gallinae is particularly severe. While a mourning dove will sometimes host it without symptoms, it will often cause yellowish growth in the mouth and esophagus that will eventually starve the host to death. Avian pox is a common, insect-vectored disease.

 

The primary predators of this species are diurnal birds of prey, such as falcons and hawks. During nesting, corvids, grackles, housecats, or rat snakes will prey on their eggs. Cowbirds rarely parasitize mourning dove nests. Mourning doves reject slightly under a third of cowbird eggs in such nests, and the mourning dove's vegetarian diet is unsuitable for cowbirds.

 

Behavior:

Like other columbids, the mourning dove drinks by suction, without lifting or tilting its head. It often gathers at drinking spots around dawn and dusk.

 

Mourning doves sunbathe or rainbathe by lying on the ground or on a flat tree limb, leaning over, stretching one wing, and keeping this posture for up to twenty minutes. These birds can also waterbathe in shallow pools or bird baths. Dustbathing is common as well.

 

Outside the breeding season, mourning doves roost communally in dense deciduous trees or in conifers. During sleep, the head rests between the shoulders, close to the body; it is not tucked under the shoulder feathers as in many other species. During the winter in Canada, roosting flights to the roosts in the evening, and out of the roosts in the morning, are delayed on colder days.

Designed in the early years of the Cold War, the massive eight-engine Boeing B-52 Stratofortress with its crew of six was intended as a high-altitude, intercontinental, strategic bomber capable of launching devastating nuclear attacks against targets deep inside the Soviet Union. Throughout the Cold War, B-52s served as the third element of the United States nuclear triad defense consisting of Intercontinental Ballistic Missiles, Submarine Launched Ballistic Missiles and strategic bombers. Yet, B-52’s have never dropped a nuclear weapon in anger.

 

Relying on speed and electronic counter-measures systems for its primary defense, the aircraft is the last bomber in U.S. history to use an air gunner (gun turret in the tail). The internal bomb bay was designed to carry up to 27,000 pounds of nuclear weapons. Modifications increased this capacity to over 40,000 pounds, wing-pylons carry an additional 18,000 pounds of bombs or missiles. The four top deck crew members, pilot, co-pilot, electronic counter measures and gunner eject upward. The navigator and bombardier eject downward from the lower level, making for uncomfortable ejections at low altitudes. 700-gallon wing tanks require wing-tip trailing wheels on landing and take-off. The droopy wings level off on take-off and move up to 15 feet as speed increases to over 500 mph. The four twin landing gear “trucks” can be turned to "crab" the aircraft in a crosswind landing. The B-52’s engines have no thrust reversers, so a very long runway, and a drag chute, is needed to help stop the aircraft on landing. With an 8,800-mile basic range the addition of air-to-air refueling makes the Stratofortress a truly global aircraft.

 

Undergoing continuous modification since it first entered service in 1955, improvements in low-level operations, conventional bombing, range and defensive and offensive systems have allowed the Stratofortress to play an important role in conflicts around the world. From the sweltering jungles of Southeast Asia to the arid wastelands of Iraq, from the dense forests of Yugoslavia to the rocky precipices of the Hindu Kush the 70,000-pound bomb load of the B-52 has supported generations of American fighting men as a tactical bomber directly targeting enemy formations and supply routes.

 

Today, the longest-lived front-line bomber in aviation history, a total of 744 B-52s were produced by Boeing at its Seattle, Washington and Wichita, Kansas plants before aircraft production ceased in 1962. Today, 76 B-52H models are still in-service with the Air Force expecting them to continue until 2040.

 

The museum's B-52D, serial number 55-0679, was manufactured by Boeing Aircraft, Wichita, Kansas and delivered to the Air Force on June 5, 1957. During the Vietnam Conflict, it flew 175 combat missions in 41 months from November 1966 to October 1973. In 1975, it was involved in a ground mishap at March AFB that resulted in a broken wing spar permanently grounding the aircraft. 55-0679 last served as a weapons loading trainer before it was declared surplus and assigned to the museum. This aircraft is on loan from the NMUSAF

The Belfast was developed to meet a Royal Air Force operational requirement (ASR.371) for a freighter capable of carrying a wide range of military loads over long ranges. The military loads envisaged included artillery, more than 200 troops, helicopters, and guided missiles. Shorts' design was based on studies they had worked on in the late 1950s and the project started as the SC.5/10 in February 1959. From that design, the prototype Belfast first flew on 5 January 1964.

 

The Belfast was notable for being only the second aircraft type to be built equipped with autoland blind landing equipment.

 

To meet the demands of the specification the Belfast used a high wing carrying four Rolls-Royce Tyne turboprops. The cargo deck, 64 ft long (20 m) in a fuselage over 18 ft in diameter (5.5 m) (roomy enough for two single-deck buses), was reached through a "beaver tail" with rear loading doors and integral ramp. The main undercarriage was two 8-wheel bogies and a 2-wheel nose. The Belfast was capable of a maximum takeoff weight (MTOW) of over 220,500 lb (100 tonnes) - less than the contemporaneous 250-tonne Antonov An-22 and the 128-tonne Douglas C-133 Cargomaster, but more than the C-130 Hercules. It could carry 150 troops with full equipment, or a Chieftain tank or two Westland Wessex helicopters or six Westland Scout helicopters.

 

The original RAF requirement had foreseen a fleet of 30 aircraft, but this number was to be significantly curtailed as a result of the Sterling Crisis of 1965. The United Kingdom government needed to gain support for its loan application to the International Monetary Fund, which the United States provided. However, one of the alleged clauses for this support was that the RAF purchase Lockheed C-130 Hercules aircraft. With a surplus of airlifting capacity the original order was reduced to 10. The Belfast entered service with No. 53 Squadron RAF in January 1966 based at RAF Fairford. By May the following year they had been moved to RAF Brize Norton.

 

Following entry to RAF service it became apparent that a major drag problem was preventing the initial five aircraft attaining Short’s desired performance. Suction drag on the tail and rear fuselage was so severe that the RAF personnel gave the aircraft the nicknames "The Dragmaster", "Slug" and "Belslow". Modifications and testing were carried out, particularly on aircraft SH1818 (which was at the time perfecting the RAF’s requirement for CAT 3 automated landings at RAE Bedford) and a new rear fairing was built improving the fleet’s cruising speed by 40 mph.

 

The reorganisation of the new RAF Strike Command was to have repercussions on the RAF’s Belfast fleet and ushered in the retirement of a number of aircraft types, including the Bristol Britannia and De Havilland Comet in 1975. By the end of 1976 the Belfast fleet had been retired and flown to RAF Kemble for storage.

 

TAC HeavyLift then purchased five of them for commercial use in 1977 and operated three of them from 1980 after they had received work so they could be certificated to civil standards. Ironically, some of them were later chartered during the Falklands war, with some sources suggesting that this cost more than keeping all the aircraft in RAF service until the 1990s. HeavyLift's Belfasts were again contracted to support the RAF during the first Gulf War, transporting vehicles and helicopters too large to be carried by the Hercules fleet.

 

Alternative to other CSC offerings, this capable camera made by the most evolving electronics company is a interesting offering now, when the NX300 is here. Large APS-C sensor with usable ISO 3200, easy handling, very solid build, many functions for both amateur and advanced photographers, full controls, WiFi connectivity, 8 fps, and very good lenses. The 18-55 is really nice, and firmware modifications made the auto focus faster and raw files smaller. Now when the production life of the NX210 comes to an end, some local resellers run crazy and the price is falling like a stone - I found this one for $250 with some benefits. For that money it´s a quite powerful and handy camera.

Almost ALL the sample photos of this camera do not capture what it is capable of. I took these photos on program mode. Sharpness for the majority of the images is bumped up one notch, but with a sensor this size, it does a nice job of in camera sharpening. This was with the kit lens. Saturation and contrast were both left at default. There may be one or two where I bumped up contrast on the humming bird feeder, but the rest are regular photos strait from program mode. I am convinced that the majority of photos of this camera posted to flickr have HDR set to ON which is the camera default. So it is set to OFF on all the photos which may account for why there is more observed contrast.

 

This camera is fast. Ive owned the the Epm2, the canon t1i, the GF6 and this is by far my favorite camera. My camera search has after all these years officially ended. This is it.

 

I will say that when I first looked at the pictures, I looked at them on a dell laptop with a poor Intel graphics card. Even with a nice monitor viewed in windows viewer I was not all moved by the photos. Then I hooked that same external monitor (a dell s2340mc set on movie mode default) on a laptop with a good graphics card.... It looks fantastic. And Im positive its not just the monitor making the pictures look nice. Ive compared the pictures against other cameras. The sensor on this camera is outstanding. Ive compared the Nikon 3200, and several other DSLRs and still prefer this. it keeps good contrast and the black/contrast ratio in my opinion is one of the larger factors in bringing photos to life.

 

And THANK YOU Sony for NOT programming auto focus to fix on the nearest subject like canon does. I once used a Canon T1i, and that thing focused on everything CLOSE to the subject. It also overexposed everything. In fact that was one of the reasons I looked at this camera. The whole rebel series...even the upper rebels over all these years tend to overexpose everything on almost every mode with the ones Ive used. This one has a very very good metering system. Just overall very impressed. Fast speed. fast autofocus, good contrast ratio (OFF HDR MODE unlike the majority of uploads of this camera to flickr), defiantly a great camera. AND as an added bonus, there are hundreds of INEXPENSIVE lenses, including all the non-MD Minoltas

In 1937, the Imperial Japanese Navy issued a requirement for a replacement for the Mitsubishi A5M then entering service. The IJN wanted a carrier-capable fighter with a top speed of 300 mph, an endurance of eight hours, cannon armament, good maneuverability, with a wingspan less than 40 feet—the width of elevators on Japanese aircraft carriers. All of this had to be done with an existing powerplant.

 

Nakajima promptly declared that the IJN was asking the impossible and did not bother trying to submit a design. Mitsubishi’s chief designer, Jiro Horikoshi, felt differently and began working on a prototype. Using the Nakajima Sakae 12 as the powerplant, he lightened his design as much as physically possible, leaving off all crew armor and self-sealing fuel tanks, and using a special kind of light but brittle duralumin in its construction. Though it delayed production, the wing and fuselage were constructed as a single piece for better durability. Using flush riveting also made for an aerodynamically clean design; it had a stall speed below that of any contemporary fighter at 70 mph. Its wide tracked landing gear also made it fairly simple to recover on both carriers and land on unimproved airstrips. Horikoshi had delivered, and the IJN accepted the new fighter into service in July 1940 as the A6M Rei-sen (Type 0), referring to the Imperial calendar date used by the Emperor of Japan; 1940 was Imperial year 2400. Both friend and foe would refer to the A6M simply as the Zero.

 

The Zero had its first combat encounter with Chinese Polikarpov I-16s in September 1940, a fighter that was the equal of the A5Ms and Ki-27s then in Japanese service, yet 13 Zeroes were easily able to handle 27 I-16s, shooting all of them down without loss in three minutes. Claire Chennault, the American advisor to the Chinese Nationalists, sent reports of this amazing new fighter to the United States, but he was ignored. The Allies would therefore learn of the Zero’s prowess first-hand on 7 December 1941 at Pearl Harbor. Making matters worse for the Allies was that the Zeroes they encountered were flown by IJN pilots, who were among the best in the world. Teaming elite pilots with a supremely maneuverable fighter was a deadly combination that seemed unstoppable in 1942, when Zeroes over New Guinea sustained a kill ratio of 12 to 1 over Allied opponents.

 

Even at this dark stage of the war for the Allies, however, their pilots were learning the Zero’s weaknesses. Hirokoshi’s sacrifices had given the Japanese a fast, maneuverable, and very long-ranged fighter, but it had come at a price. P-40 and F4F Wildcat pilots in China and the Pacific learned that the Zero, lacking any sort of armor or self-sealing fuel tanks, was very prone to catching fire and exploding with only a few hits. They also learned that the best defense against a Zero was to dive away from it, as Japanese pilots could not keep up with either the P-40 or the F4F in a dive, as it would tear their fragile fighter apart. These sort of tactics allowed Allied pilots to survive and learn how to deal with the Japanese fighter. Japanese pilots also learned that the rifle-caliber 7.7mm machine guns in the Zero’s cowl were ineffective aganst armored Allied fighters, and the 20mm cannon often had poor fusing on the shells. The Allies gave the Zero the reporting name “Zeke,” while later models were codenamed “Hamp” and floatplane A6M2-Ns were codenamed “Rufe,” but most pilots continued to call it the Zero.

 

As World War II continued, the Allies began drawing on those lessons in fighter design, helped immensely when an intact A6M2 was captured in the Aleutians in summer 1942. First to arrive was the F4U Corsair, which still could not turn with the Zero but was faster and better in a climb; the second was the F6F Hellcat, which was also faster and better in the vertical, but could stay with the Zero in a sustained turn. The Allies also benefited from the Japanese losing so many experienced pilots in battles such as Midway and the Guadalcanal campaign: the IJN’s pilot replacement program was too selective, and could not replace the heavy losses of 1942 and 1943. Japanese industry was also slow to come up with a replacement for the A6M.

 

As a result, by late 1943, the Zero menace had been reduced drastically; the Battle of the Philippine Sea—which US Navy pilots named the “Great Marianas Turkey Shoot”—brought this out dramatically, when nearly 700 Japanese aircraft, a significant number of which were A6Ms, were shot down with less than 40 losses among the Americans. While the Zero was still deadly in the hands of a good pilot, these pilots were increasingly scarce by 1945. Though Mitsubishi kept upgrading the Zero throughout World War II, the design simply was too specialized to do much with. By 1945, it was being used mainly as a kamikaze suicide aircraft, flown by half-trained former college students. While the kamikazes did a great deal of damage and killed thousands of Allied sailors, it was a desperation tactic that only lengthened a war that Japan had already lost. The Zero had exacted a price, however: it was responsible for the loss of 1550 Allied aircraft, a conservative estimate.

 

By war’s end, 10, 939 A6Ms had been built and Mitsubishi was working on a replacement, the similar A7M Reppu. Of these, the aircraft that survived the war were mostly scrapped and few preserved, and no flyable aircraft were left; directors attempting to make World War II movies were forced to convert a number of T-6 Texan trainers to look something like Zeroes. A few have since been restored to flying condition. Today, about 17 Zeroes remain, though some are being recovered from wartime wreck sites and restored to museum display.

 

This A6M3 belongs to the Flying Heritage Collection of Everett, Washington, and is one of the few flyable Zeroes left today. It was originally assigned to the 251st Kokutai at Babo, New Guinea, but was destroyed in an Allied bombing raid in 1943. In the early 1990s, the Zero was recovered by the Santa Monica Museum of Flying, and in 1994 sent to Russia to be restored. Many of the parts needed to be machined from scratch, and it uses a modified Pratt and Whitney R-1830 Twin Wasp engine (ironically, the same engine used by the F4F Wildcat). Following restoration, it was bought by the FHC and is now part of their collection. It is painted overall light olive drab, with dark green stripes for camouflage; the silver spinner and propeller blades indicate a Mitsubishi-built aircraft.

 

The SPAD S.XIII was one of the most capable fighters of World War One. The type first flew in April 1917 and 8,472 had been built by the end of the War. Many well-known pilots flew the type in combat, including French pilots Georges Guynemer and Rene Fonk, Italian Francesco Baracca and Americans Eddie Rickenbacker and Frank Luke.

Several saw Belgian service after March 1918 with the last not being retired until 1928.

This is a genuine Belgian example which was gifted to the museum in 1920/1921. Since restored, it remains on display at what is known as the Brussels Air Museum, although it is actually the Air and Space Section of the Royal Museum of the Armed Forces and Military History.

The Merlin is a large, three-engined helicopter capable of long-range autonomous operations. There are three main versions for naval, military and civilian use. The only version currently in Royal Navy use is the Merlin HM MK1 (formerly Merlin EH101), this is an Anti-Submarine (ASW) variant of the EH101 helicopter. The first aircraft was delivered in December 1998, to begin the replacement of the ageing ASW Sea King (Mk6), and the last of the 44 on order was somewhat belatedly delivered in late 2003.

 

Merlin is designed to operate in all weathers from the flight decks of both large and small ships (Invincible class aircraft carriers and Type 23 frigates). It is powered by three Rolls Royce RTM 322 engines, is capable of speeds of up to 150 knots and has a range of 200 nautical miles. It can carry up to four homing torpedoes or depth charges, for use against threat submarines and can provide targeting information via datalink for the prosecution of surface threats. The Merlin retains all the secondary role capability of its predecessor, the Sea King, including loadlifting (vertrep), casualty evacuation, troop carrying and Search and Rescue (SAR).

The Dynamic Desktop is capable of interacting with countless items thanks to conductive materials and Ideum's GestureWorks software. The Desktop can now tell the difference between post-its, keyboards, thermoses, and anything else you could possibly need on hand while working.

Mission

The C-17 Globemaster III is the newest, most flexible cargo aircraft to enter the airlift force. The C-17 is capable of rapid strategic delivery of troops and all types of cargo to main operating bases or directly to forward bases in the deployment area. The aircraft can perform tactical airlift and airdrop missions and can also transport litters and ambulatory patients during aeromedical evacuations when required. The inherent flexibility and performance of the C-17 force improve the ability of the total airlift system to fulfill the worldwide air mobility requirements of the United States.

 

The ultimate measure of airlift effectiveness is the ability to rapidly project and sustain an effective combat force close to a potential battle area. Threats to U.S. interests have changed in recent years, and the size and weight of U.S.-mechanized firepower and equipment have grown in response to improved capabilities of potential adversaries. This trend has significantly increased air mobility requirements, particularly in the area of large or heavy outsize cargo. As a result, newer and more flexible airlift aircraft are needed to meet potential armed contingencies, peacekeeping or humanitarian missions worldwide. The C-17 is capable of meeting today's demanding airlift missions.

 

Features

Reliability and maintainability are two outstanding benefits of the C-17 system. Current operational requirements impose demanding reliability and maintainability. These requirements include an aircraft mission completion success probability rate of 92 percent, only 20 aircraft maintenance man-hours per flying hour, and full and partial mission availability rates of 74.7 and 82.5 percent, respectively. The Boeing warranty assures these figures will be met.

 

The C-17 measures 174 feet long (53 meters) with a wingspan of 169 feet, 10 inches (51.75 meters). The aircraft is powered by four, fully reversible, Federal Aviation Administration-certified F117-PW-100 engines (the military designation for the commercial Pratt & Whitney PW2040), currently used on the Boeing 757. Each engine is rated at 40,440 pounds of thrust. The thrust reversers direct the flow of air upward and forward to avoid ingestion of dust and debris. Maximum use has been made of off-the-shelf and commercial equipment, including Air Force-standardized avionics.

 

The aircraft is operated by a crew of three (pilot, copilot and loadmaster), reducing manpower requirements, risk exposure and long-term operating costs. Cargo is loaded onto the C-17 through a large aft door that accommodates military vehicles and palletized cargo. The C-17 can carry virtually all of the Army's air-transportable equipment.

 

Maximum payload capacity of the C-17 is 170,900 pounds (77,519 kilograms), and its maximum gross takeoff weight is 585,000 pounds (265,352 kilograms). With a payload of 169,000 pounds (76,657 kilograms) and an initial cruise altitude of 28,000 feet (8,534 meters), the C-17 has an unrefueled range of approximately 2,400 nautical miles. Its cruise speed is approximately 450 knots (.76 Mach). The C-17 is designed to airdrop 102 paratroopers and equipment.

 

The design of the aircraft allows it to operate through small, austere airfields. The C-17 can take off and land on runways as short as 3,500 feet (1,064 meters) and only 90 feet wide (27.4 meters). Even on such narrow runways, the C-17 can turn around using a three-point star turn and its backing capability.

 

Background

The C-17 made its maiden flight on Sept. 15, 1991, and the first production model was delivered to Charleston Air Force Base, S.C., June 14, 1993. The first squadron of C-17s, the 17th Airlift Squadron, was declared operationally ready Jan. 17, 1995. The Air Force originally programmed to buy a total of 120 C-17s, with the last one being delivered in November 2004. Current budget plans involve purchasing 190 aircraft.

 

The original 120 C-17s were based at Charleston AFB; McChord AFB, Wash., (first aircraft arrived in July 1999); Altus AFB, Okla.; and at an Air National Guard unit in Jackson, Miss. In August 2005, March Air Reserve Base, Calif., began basing the first of eight aircraft. In February 2006, Hickam AFB, Hawaii, received its first C-17.

 

The C-17 is operated by the Air Mobility Command at the 60th Airlift Wing and the 349th Air Mobility Wing (Associate Reserve) at Travis AFB, Calif.; 62nd Airlift Wing and 446th Airlift Wing (Associate Reserve) at McChord AFB, Wash.; 437th Airlift Wing and 315th Airlift Wing (Associate Reserve) at Charleston AFB, S.C.; the 305th Air Mobility Wing, McGuire AFB, N.J.; and the 172nd Airlift Wing, Mississippi ANG. Additionally, Air Force Materiel Command operates two C-17s at Edwards AFB, Calif., and Pacific Air Forces operates eight aircraft each at Elmendorf AFB, Alaska and Hickam AFB, Hawaii (Associate Guard). The Air Force Reserve Command operates eight aircraft at March Air Reserve Base, Calif; and Air Education and Training Command has 12 aircraft at Altus AFB, Okla.

 

The FH-5 series are capable of measuring Micro/Macro Vickers, Knoop and Brinell scales of hardness, from HV 0.02 to HV 50, up to a maximum of 62.5kg load. The FH5 is a digital tester with a fine loadcell based force feedback control loop for fast, reliable and repeatable measurements and also allows a huge selection of test loads and test rates for almost any test condition. In addition, the tester has a four position turret that can be customised by using different indentors, objectives, stages or vision systems, making the FH5 extremely flexible.

Aeroscopia is a French aeronautical museum located in Blagnac (Haute-Garonne), near the AéroConstellation site, and notably hosts two copies of the Concorde, which opened on January 14, 2015

 

The south tarmac of the museum can only accommodate three large aircraft. The installation of the devices was definitively finished after the first prototype of the A400M-180 arrived there on July 16, 2015, despite the possibility of 360,000 euros in VAT.

In 1937, the Imperial Japanese Navy issued a requirement for a replacement for the Mitsubishi A5M then entering service. The IJN wanted a carrier-capable fighter with a top speed of 300 mph, an endurance of eight hours, cannon armament, good maneuverability, with a wingspan less than 40 feet—the width of elevators on Japanese aircraft carriers. All of this had to be done with an existing powerplant.

 

Nakajima promptly declared that the IJN was asking the impossible and did not bother trying to submit a design. Mitsubishi’s chief designer, Jiro Horikoshi, felt differently and began working on a prototype. Using the Nakajima Sakae 12 as the powerplant, he lightened his design as much as physically possible, leaving off all crew armor and self-sealing fuel tanks, and using a special kind of light but brittle duralumin in its construction. Though it delayed production, the wing and fuselage were constructed as a single piece for better durability. Using flush riveting also made for an aerodynamically clean design; it had a stall speed below that of any contemporary fighter at 70 mph. Its wide tracked landing gear also made it fairly simple to recover on both carriers and land on unimproved airstrips. Horikoshi had delivered, and the IJN accepted the new fighter into service in July 1940 as the A6M Rei-sen (Type 0), referring to the Imperial calendar date used by the Emperor of Japan; 1940 was Imperial year 2400. Both friend and foe would refer to the A6M simply as the Zero.

 

The Zero had its first combat encounter with Chinese Polikarpov I-16s in September 1940, a fighter that was the equal of the A5Ms and Ki-27s then in Japanese service, yet 13 Zeroes were easily able to handle 27 I-16s, shooting all of them down without loss in three minutes. Claire Chennault, the American advisor to the Chinese Nationalists, sent reports of this amazing new fighter to the United States, but he was ignored. The Allies would therefore learn of the Zero’s prowess first-hand on 7 December 1941 at Pearl Harbor. Making matters worse for the Allies was that the Zeroes they encountered were flown by IJN pilots, who were among the best in the world. Teaming elite pilots with a supremely maneuverable fighter was a deadly combination that seemed unstoppable in 1942, when Zeroes over New Guinea sustained a kill ratio of 12 to 1 over Allied opponents.

 

Even at this dark stage of the war for the Allies, however, their pilots were learning the Zero’s weaknesses. Hirokoshi’s sacrifices had given the Japanese an excellent and very long-ranged fighter (A6Ms regularly made the round trip between Rabaul and Guadalcanal in 1942), but it had come at a price. P-40 and F4F Wildcat pilots in China and the Pacific learned that the Zero, lacking any sort of armor or self-sealing fuel tanks, was very prone to catching fire and exploding with only a few hits. They also learned that the best defense against a Zero was to dive away from it, as Japanese pilots could not keep up with either the P-40 or the F4F in a dive, as it would tear their fragile fighter apart. While trying to dogfight a Zero was suicide, Allied pilots could use the vertical to their advantage. Japanese pilots also learned that the rifle-caliber 7.7mm machine guns in the Zero’s cowl were ineffective against armored Allied fighters, and the 20mm cannon often had poor fusing on the shells. The Allies gave the Zero the reporting name “Zeke,” while later models were codenamed “Hamp” and floatplane A6M2-Ns were codenamed “Rufe,” but most pilots continued to call it the Zero.

 

As World War II continued, the Allies began drawing on those lessons in fighter design, helped immensely when an intact A6M2 was captured in the Aleutians in summer 1942. First to arrive was the F4U Corsair, which still could not turn with the Zero but was faster and better in a climb; the second was the F6F Hellcat, which was also faster and better in the vertical, but could stay with the Zero in a sustained turn. The Allies also benefited from the Japanese losing so many experienced pilots in battles such as Midway and the Guadalcanal campaign: the IJN’s pilot replacement program was too selective, and could not replace the heavy losses of 1942 and 1943. Japanese industry was also slow to come up with a replacement for the A6M. As a result, by late 1943, the Zero menace had been reduced drastically; the Battle of the Philippine Sea—which US Navy pilots named the “Great Marianas Turkey Shoot”—brought this out dramatically, when nearly 700 Japanese aircraft, a significant number of which were A6Ms, were shot down with less than 40 losses among the Americans. While the Zero was still deadly in the hands of a good pilot, these pilots were increasingly scarce by 1945.

 

Though Mitsubishi kept upgrading the Zero throughout World War II, the design simply was too specialized to do much with. By 1945, it was being used mainly as a kamikaze suicide aircraft, flown by half-trained former college students. While the kamikazes did a great deal of damage and killed thousands of Allied sailors, it was a desperation tactic that only lengthened a war that Japan had already lost. The Zero had exacted a price, however: it was responsible for the loss of 1550 Allied aircraft, a conservative estimate.

 

By war’s end, 10, 939 A6Ms had been built and Mitsubishi was working on a replacement, the similar A7M Reppu. Of these, the aircraft that survived the war were mostly scrapped and few preserved, and no flyable aircraft were left; directors attempting to make World War II movies were forced to convert a number of T-6 Texan trainers to look something like Zeroes. A few have since been restored to flying condition. Today, about 17 Zeroes remain, though some are being recovered from wartime wreck sites and restored to museum display.

 

The Zero seen here is a late war A6M5, painted as an Imperial Japanese Army Air Force aircraft with dark green over light gray; as indicated by the brown propeller blades, this aircraft is one of many manufactured by Nakajima under license during the war. HK-102 was captured intact at Truk, tested in the US, and went through various collectors until acquired by the Planes of Fame museum in California. It is not currently flyable, though it could be quickly restored to flying condition; as of this writing, it is only a display aircraft at the Flying Heritage Collection in Everett, WA. The FHC acquired HK-102 in 2001.

NEOBALLS / ZEN MAGNETS - Neodymium Magnetic Balls (@4205) - Starcraft II's Massive Thor

 

This is my most complex and largest build to date.

 

It was designed in parts: Cockpit body, then legs, then arms, then rear guns. Then I had to redesign parts when it came time to assemble it together because of incorrect bonding assumptions and misalignment of magnet fields.

 

Experimented with x-beam coupled bonds to get the maximum lateral strength with reinforcements on the sides. This proved to be very string. Created a X-Beam using similar methods producing a very strong leg structure. It was capable of support the entire weight of the cockpit body w/o a problem. Had to redesign the leg to cockpit body mount point from the earlier concept because the bond was not completely coupled.

 

Next up were the arm/guns ... the weight was too much for the cockpit body to support so I fashioned a pair of lego-platforms for them to rest on and take the weight off of the central body.

 

Finally ... the rear guns ... these were a challenge in that their original mount point design had to be reworked also to make them fit correctly into the rear of the cockpit body. I changed the mount points on the guns to fit the space on both sides and added a few support balls to improve the mount point bonds. I was very surprised how they were balanced and supported only by two point sections to the body. The guns stayed in place for a small series of photos.

 

The design flaw was in the side bonds of the beam to the legs. The coupled field held nicely for a short amount of time and would have held if it didn't have the weight of the rear guns to support. When they were standing upright and straight, all was good. As soon as I attempted to move the platform forward (to take a video), the rear guns tilted slightly backwards and and that was the end of the leg to body support bonds ... and created the dreaded implosion.

 

The rear gun weight caused the entire central body section to rotate backwards and fall back on the rear guns ... taking the arms in the process. Perhaps I should have created a Lego-support structure for the rear guns to remove the pendulum force backwards ... but that would have created another view blocker like the side Lego-platforms obstructed the view of the legs and feet. Not sure if I can recreate it for a rotational video ... this took over a week (on/off to design and assemble).

 

Overall ... I was very happy with the result ... hope I captured enough detail to warrant some visual recognition as a Starcraft II Thor reproduction/interpretation.

 

This was design and built for the Zen Magnets Contest 26: The Massive Thor

Wildland Firefighters on Rappel capable crews, come from all over the nation each spring to train at the National Helicopter Rappel Program’s Rappel Academy at Salmon AirBase, in Salmon, Idaho.

Wildland fire aircraft play a critical role in supporting firefighters on wildland fires. Helicopters also deliver aerial crews called Heli-Rappellers to wildland fires. These are specially trained firefighters that rappel from helicopters in order to effectively and quickly respond to fires in remote terrain.

Heli-Rappellers may land near a wildfire but if there is no landing zone close by they can utilize their skills to rappel from the hovering helicopter. Once on the ground, crews build firelines using hand tools, chainsaws, and other firefighting tools. (Forest Service photo by Charity Parks)

The Corsair is widely considered the most capable of all carrier-based fighter aircraft of World War Two. Designed and originally built by Chance Vought, it was also manufactured under license by Goodyear at the height of production during the Second World War. Its distinctive "bent" wings were designed to keep the landing gear short and robust for carrier landings and give clearance for the enormous 13' 4" diameter propeller required to pull her to over 400 MPH - the first American fighter to do so. It was considered the performance equal to many other fighters like the Mustang but its short range kept it either carrier-based or land-based in the South Pacific war close to the action. The Corsair continued to be operated by the USN and the Marines after the war and saw considerable action during the Korean War.

 

Corsairs were first operated from carriers by the Fleet Air Arm of the Royal Navy. Trained in the US, RNFAA pilots including Canadian Lt. Robert Hampton Gray were deployed on carriers such as HMS Formidable and Victorious and carried out daring fighter escort and attack operations in the North Atlantic. This included the famous raids against the holed-up German battleship Tirpitz. HMS Formidable also fought in the Pacific theatre later in the war where Lt. Gray won the Victoria Cross. The Vintage Wings of Canada Corsair, presently in standard U.S. “shipyard blue” markings, will be painted in markings to honour Hampton Gray.

 

In 1937, the Imperial Japanese Navy issued a requirement for a replacement for the Mitsubishi A5M then entering service. The IJN wanted a carrier-capable fighter with a top speed of 300 mph, an endurance of eight hours, cannon armament, good maneuverability, with a wingspan less than 40 feet—the width of elevators on Japanese aircraft carriers. All of this had to be done with an existing powerplant.

 

Nakajima promptly declared that the IJN was asking the impossible and did not bother trying to submit a design. Mitsubishi’s chief designer, Jiro Horikoshi, felt differently and began working on a prototype. Using the Nakajima Sakae 12 as the powerplant, he lightened his design as much as physically possible, leaving off all crew armor and self-sealing fuel tanks, and using a special kind of light but brittle duralumin in its construction. Though it delayed production, the wing and fuselage were constructed as a single piece for better durability. Using flush riveting also made for an aerodynamically clean design; it had a stall speed below that of any contemporary fighter at 70 mph. Its wide tracked landing gear also made it fairly simple to recover on both carriers and land on unimproved airstrips. Horikoshi had delivered, and the IJN accepted the new fighter into service in July 1940 as the A6M Rei-sen (Type 0), referring to the Imperial calendar date used by the Emperor of Japan; 1940 was Imperial year 2400. Both friend and foe would refer to the A6M simply as the Zero.

 

The Zero had its first combat encounter with Chinese Polikarpov I-16s in September 1940, a fighter that was the equal of the A5Ms and Ki-27s then in Japanese service, yet 13 Zeroes were easily able to handle 27 I-16s, shooting all of them down without loss in three minutes. Claire Chennault, the American advisor to the Chinese Nationalists, sent reports of this amazing new fighter to the United States, but he was ignored. The Allies would therefore learn of the Zero’s prowess first-hand on 7 December 1941 at Pearl Harbor. Making matters worse for the Allies was that the Zeroes they encountered were flown by IJN pilots, who were among the best in the world. Teaming elite pilots with a supremely maneuverable fighter was a deadly combination that seemed unstoppable in 1942, when Zeroes over New Guinea sustained a kill ratio of 12 to 1 over Allied opponents.

 

Even at this dark stage of the war for the Allies, however, their pilots were learning the Zero’s weaknesses. Hirokoshi’s sacrifices had given the Japanese an excellent and very long-ranged fighter (A6Ms regularly made the round trip between Rabaul and Guadalcanal in 1942), but it had come at a price. P-40 and F4F Wildcat pilots in China and the Pacific learned that the Zero, lacking any sort of armor or self-sealing fuel tanks, was very prone to catching fire and exploding with only a few hits. They also learned that the best defense against a Zero was to dive away from it, as Japanese pilots could not keep up with either the P-40 or the F4F in a dive, as it would tear their fragile fighter apart. While trying to dogfight a Zero was suicide, Allied pilots could use the vertical to their advantage. Japanese pilots also learned that the rifle-caliber 7.7mm machine guns in the Zero’s cowl were ineffective against armored Allied fighters, and the 20mm cannon often had poor fusing on the shells. The Allies gave the Zero the reporting name “Zeke,” while later models were codenamed “Hamp” and floatplane A6M2-Ns were codenamed “Rufe,” but most pilots continued to call it the Zero.

 

As World War II continued, the Allies began drawing on those lessons in fighter design, helped immensely when an intact A6M2 was captured in the Aleutians in summer 1942. First to arrive was the F4U Corsair, which still could not turn with the Zero but was faster and better in a climb; the second was the F6F Hellcat, which was also faster and better in the vertical, but could stay with the Zero in a sustained turn. The Allies also benefited from the Japanese losing so many experienced pilots in battles such as Midway and the Guadalcanal campaign: the IJN’s pilot replacement program was too selective, and could not replace the heavy losses of 1942 and 1943. Japanese industry was also slow to come up with a replacement for the A6M. As a result, by late 1943, the Zero menace had been reduced drastically; the Battle of the Philippine Sea—which US Navy pilots named the “Great Marianas Turkey Shoot”—brought this out dramatically, when nearly 700 Japanese aircraft, a significant number of which were A6Ms, were shot down with less than 40 losses among the Americans. While the Zero was still deadly in the hands of a good pilot, these pilots were increasingly scarce by 1945.

 

Though Mitsubishi kept upgrading the Zero throughout World War II, the design simply was too specialized to do much with. By 1945, it was being used mainly as a kamikaze suicide aircraft, flown by half-trained former college students. While the kamikazes did a great deal of damage and killed thousands of Allied sailors, it was a desperation tactic that only lengthened a war that Japan had already lost. The Zero had exacted a price, however: it was responsible for the loss of 1550 Allied aircraft, a conservative estimate.

 

By war’s end, 10, 939 A6Ms had been built and Mitsubishi was working on a replacement, the similar A7M Reppu. Of these, the aircraft that survived the war were mostly scrapped and few preserved, and no flyable aircraft were left; directors attempting to make World War II movies were forced to convert a number of T-6 Texan trainers to look something like Zeroes. A few have since been restored to flying condition. Today, about 17 Zeroes remain, though some are being recovered from wartime wreck sites and restored to museum display.

 

This is the Smithsonian Air and Space Museum's A6M5, originally assigned to the 261st Kokutai on Saipan. Captured in flyable condition in 1944, the Zero was brought back to the United States and tested until 1946. It was then donated to the Smithsonian, which at the time lacked the space to display it. It was restored in 1975 and finally went on display that year. The green over gray camouflage was typical for Imperial Japanese Army Air Force; the black cowling was typical for a Zero, and the yellow leading edges were for recognition purposes. The brown hub and propeller blades indicated a Nakajima-built Zero; Nakajima built several hundred under license.

NEOBALLS / ZEN MAGNETS - Neodymium Magnetic Balls (@4205) - Starcraft II's Massive Thor

 

This is my most complex and largest build to date.

 

It was designed in parts: Cockpit body, then legs, then arms, then rear guns. Then I had to redesign parts when it came time to assemble it together because of incorrect bonding assumptions and misalignment of magnet fields.

 

Experimented with x-beam coupled bonds to get the maximum lateral strength with reinforcements on the sides. This proved to be very string. Created a X-Beam using similar methods producing a very strong leg structure. It was capable of support the entire weight of the cockpit body w/o a problem. Had to redesign the leg to cockpit body mount point from the earlier concept because the bond was not completely coupled.

 

Next up were the arm/guns ... the weight was too much for the cockpit body to support so I fashioned a pair of lego-platforms for them to rest on and take the weight off of the central body.

 

Finally ... the rear guns ... these were a challenge in that their original mount point design had to be reworked also to make them fit correctly into the rear of the cockpit body. I changed the mount points on the guns to fit the space on both sides and added a few support balls to improve the mount point bonds. I was very surprised how they were balanced and supported only by two point sections to the body. The guns stayed in place for a small series of photos.

 

The design flaw was in the side bonds of the beam to the legs. The coupled field held nicely for a short amount of time and would have held if it didn't have the weight of the rear guns to support. When they were standing upright and straight, all was good. As soon as I attempted to move the platform forward (to take a video), the rear guns tilted slightly backwards and and that was the end of the leg to body support bonds ... and created the dreaded implosion.

 

The rear gun weight caused the entire central body section to rotate backwards and fall back on the rear guns ... taking the arms in the process. Perhaps I should have created a Lego-support structure for the rear guns to remove the pendulum force backwards ... but that would have created another view blocker like the side Lego-platforms obstructed the view of the legs and feet. Not sure if I can recreate it for a rotational video ... this took over a week (on/off to design and assemble).

 

Overall ... I was very happy with the result ... hope I captured enough detail to warrant some visual recognition as a Starcraft II Thor reproduction/interpretation.

 

This was design and built for the Zen Magnets Contest 26: The Massive Thor

The Eurocopter EC135 is a twin-engine civil helicopter produced by Eurocopter, widely used amongst police and ambulance services and for executive transport. It is capable of flight under instrument flight rules (IFR) and is outfitted with digital flight controls. Entering service in 1996, over a thousand aircraft have been produced to date.

 

The EC135 started development prior to the formation of Eurocopter under Messerschmitt-Bölkow-Blohm (MBB) under the designation Bo 108 by MBB in the 1970s. Working in partnership with Aerospatiale, the Bo 108 was initially intended to be a technology demonstrator, combining attributes of the successful MBB Bo 105 with new advances and an aerodynamically streamlined design.[2] Technologies included on the Bo 108 included the first full-authority digital engine controls (FADEC) on a helicopter, a bearingless main rotor, and the adoption of a new transmission.[2] The first prototype made its first flight on 17 October 1988, powered by two Allison 250-C20R/1 engines. A second BO 108 followed on 5 June 1991, this time with two Turboméca TM319-1B Arrius engines; unlike later production aircraft, both technology demonstrators flew with conventional tail rotors.

 

In the late 1990s, the design was revised with the introduction of the Fenestron tail rotor system, an advanced rigid main rotor, composite materials, and resonance isolation systems.[2] It was decided to pursue a full certification program, resulting in the production of two pre-production prototypes, under the new designation EC135 to correspond with the newly created Eurocopter company.[3] At this point, it was decided that the EC135 should be developed with two competing engines, the Turboméca Arrius 2B and the Pratt & Whitney Canada PW206B engines; both engines proved to be successful and either is available as options on production EC135s.[4]

 

The EC135 made its first public appearance in January 1995 at the Heli-Expo at Las Vegas.[2] European JAA certification was achieved on 16 June 1996, with FAA approval following on 31 July.

Built by the Schiffswerks Rieherst company in Hamburg, the Umbria was launched on December 30th 1911 with the name of Bahia Blanca. It was a large freighter by that time, 150 meters long, with a power capable of providing a speed of 14 knots that could carry 9,000 tons of cargo and up to 2,000 passengers. In 1912 it began operating the Hamburg-America line doing different jobs between Europe and Argentina until the outbreak of World War I, when it was based in Buenos Aires. In 1918 the ship was acquired by the Argentinian government and it was not until 1935 when the ship was taken over by the Italian government and renamed again: the Umbria. From that moment its trips were to transport troops and during the following two years carried several thousand soldiers to the Italian colonies in East Africa.

  

The loss of the Umbria

 

In May 1940, when Italy was still neutral in World War II, the Umbria was secretly loaded with 360,000 bombs between 15 kg and 100 kg, 60 boxes of detonators, building materials and three Fiat Lunga cars, carrying a total 8,600 tons of weapons towards the East Africa. The explosives had destination Massawa and Assab, Eritrea, that was Italian colony by then, and the rest of the cargo was heading different locations in Asia. Italy's entry into the war was imminent and this shipment was destined to the defense of the colonies against the Allies and to the possible expansion of its African territories.

   

On 3rd June 1940 the Umbria reached Port Said, northern Egypt, where loaded with 1,000 tons of coal and water in a movement to fool the Allies, trying to look like a harmless freighter. The port, controlled by the Royal Navy, and its authorities allowed the ship enter on the Red Sea three days after arrival. The British delayed the departure of the Umbria knowing that Italy's entry into the war was imminent and that the cargo of Umbria had devastating power that sooner or later would be used against the Allies and why not, to get a great load to fight fascism. But Italy, as a neutral country that it was, had every right to transport weapons much like any other cargo to its colonies.

   

Having met the deadline to be retained, the Umbria crossed the Suez Canal on June 6th but with the escort of the HMS Grimsby. The importance and destructive capacity of the cargo required it. Three days later the Umbria entered in Sudan waters and the HMS Grimsby ordered the Umbria captain to anchor on Wingate Reef under the pretext of searching for contraband. Moments later the British warship HMS Leander arrived with a group of 20 sailors who boarded the Umbria. After thoroughly searching the ship and finding nothing, the captain ordered the British troops to remain the night aboard the Umbria.

The next morning Lorenzo Muiesan, Umbria captain, was in his cabin listening to the radio when Mussolini announced the entry of Italy into the World War II. Hostilities would begin at midnight of that day. Muiesan, a very patriotic captain with long experience, was the only one in the area who had heard the news and knew immediately that both Umbria and the burden would be used by the Allies against their own country. He had no option to disable both. In a move of extraordinary intelligence, as the hours passed retained by the British who did not yet know that Italy was officially the enemy, the captain ordered his crew conducting a rescue simulation... that was more real than the British thought. This maneuver, which the English soldiers agreed as they believed it would serve to further delay the departure of the Umbria. While the Italians occupied the lifeboats, the chief engineers, following Muiesan´s orders, opened all the valves and drown the ship to the bottom of the reef. With the crew safe, the British only had time to get on their ship and watch the freighter slid slowly.

When the captain of HMS Grimsby asked why he had done that Muiesan confirmed the declaration of war from Italy to Britain. The next day Muiesan and the rest of Umbria crew departed detainees to India, where they spent four years in prison.

  

CARGO:

The Umbria was carrying 360,000 individual aircraft bombs ranging in size from 15, 50 and 100 kg. The vessel also carried a large quantity of fuses, ammunition and detonators as well as other traditional cargo. The captain knew these bombs would be confiscated and used by the enemy against his country should they ever discover them which was why he made the call to sink the ship.

The Umbria had sailed in June 1940 with 6,000 tons of bombs, 60 boxes detonators, explosives, weapons and three Fiat 1100 Lunga from Genoa via Livorno and Naples in the Suez Canal and on the way via Massaua and Assab to Calcutta.

The Indian peafowl (Pavo cristatus), also known as the common peafowl, and blue peafowl, is a peafowl species native to the Indian subcontinent. It has been introduced to many other countries. Male peafowl are referred to as peacocks, and female peafowl are referred to as peahens, although both sexes are often referred to colloquially as a "peacock".

 

Indian peafowl display a marked form of sexual dimorphism. The peacock is brightly coloured, with a predominantly blue fan-like crest of spatula-tipped wire-like feathers and is best known for the long train made up of elongated upper-tail covert feathers which bear colourful eyespots. These stiff feathers are raised into a fan and quivered in a display during courtship. Despite the length and size of these covert feathers, peacocks are still capable of flight. Peahens lack the train, have a white face and iridescent green lower neck, and dull brown plumage. The Indian peafowl lives mainly on the ground in open forest or on land under cultivation where they forage for berries, grains but also prey on snakes, lizards, and small rodents. Their loud calls make them easy to detect, and in forest areas often indicate the presence of a predator such as a tiger. They forage on the ground in small groups and usually try to escape on foot through undergrowth and avoid flying, though they fly into tall trees to roost.

 

The function of the peacock's elaborate train has been debated for over a century. In the 19th century, Charles Darwin found it a puzzle, hard to explain through ordinary natural selection. His later explanation, sexual selection, is widely but not universally accepted. In the 20th century, Amotz Zahavi argued that the train was a handicap, and that males were honestly signalling their fitness in proportion to the splendour of their trains. Despite extensive study, opinions remain divided on the mechanisms involved.

 

The bird is celebrated in Hindu and Greek mythology, and is the national bird of India. The Indian peafowl is listed as of Least Concern on the IUCN Red List.

 

Taxonomy and naming

Carl Linnaeus in his work Systema Naturae in 1758 assigned to the Indian peafowl the technical name of Pavo cristatus (means "crested peafowl" in classical Latin).

 

The earliest usage of the word in written English is from around 1300 and spelling variants include pecok, pekok, pecokk, peacocke, peacock, pyckock, poucock, pocok, pokok, pokokke, and poocok among others. The current spelling was established in the late 17th century. Chaucer (1343–1400) used the word to refer to a proud and ostentatious person in his simile "proud a pekok" in Troilus and Criseyde (Book I, line 210).

 

The Sanskrit, later Pali, and modern Hindi term for the animal is maur. It is debated that the nomenclature of the Maurya Empire, whose first emperor Chandragupta Maurya was raised and influenced by peacock farmers was named after the terminology.

 

The Greek word for peacock was taos and was related to the Persian "tavus" (as in Takht-i-Tâvus for the famed Peacock Throne). The Ancient Hebrew word tuki (plural tukkiyim) has been said to have been derived from the Tamil tokei but sometimes traced to the Egyptian tekh. In modern Hebrew the word for peacock is "tavas". In Sanskrit, the peacock is known as Mayura and is associated with the killing of snakes.

 

Description

 

Male neck detail

Peacocks are a larger sized bird with a length from bill to tail of 100 to 115 cm (39 to 45 in) and to the end of a fully grown train as much as 195 to 225 cm (77 to 89 in) and weigh 4–6 kg (8.8–13.2 lb). The females, or peahens, are smaller at around 95 cm (37 in) in length and weigh 2.75–4 kg (6.1–8.8 lb). Indian peafowl are among the largest and heaviest representatives of the Phasianidae. So far as is known, only the wild turkey grows notably heavier. The green peafowl is slightly lighter in body mass despite the male having a longer train on average than the male of the Indian species. Their size, colour and shape of crest make them unmistakable within their native distribution range. The male is metallic blue on the crown, the feathers of the head being short and curled. The fan-shaped crest on the head is made of feathers with bare black shafts and tipped with bluish-green webbing. A white stripe above the eye and a crescent shaped white patch below the eye are formed by bare white skin. The sides of the head have iridescent greenish blue feathers. The back has scaly bronze-green feathers with black and copper markings. The scapular and the wings are buff and barred in black, the primaries are chestnut and the secondaries are black. The tail is dark brown and the "train" is made up of elongated upper tail coverts (more than 200 feathers, the actual tail has only 20 feathers) and nearly all of these feathers end with an elaborate eye-spot. A few of the outer feathers lack the spot and end in a crescent shaped black tip. The underside is dark glossy green shading into blackish under the tail. The thighs are buff coloured. The male has a spur on the leg above the hind toe.

 

The adult peahen has a rufous-brown head with a crest as in the male but the tips are chestnut edged with green. The upper body is brownish with pale mottling. The primaries, secondaries and tail are dark brown. The lower neck is metallic green and the breast feathers are dark brown glossed with green. The remaining underparts are whitish. Downy young are pale buff with a dark brown mark on the nape that connects with the eyes. Young males look like the females but the wings are chestnut coloured.

 

The most common calls are a loud pia-ow or may-awe. The frequency of calling increases before the Monsoon season and may be delivered in alarm or when disturbed by loud noises. In forests, their calls often indicate the presence of a predators such as the tiger. They also make many other calls such as a rapid series of ka-aan..ka-aan or a rapid kok-kok. They often emit an explosive low-pitched honk! when agitated.

 

Mutations and hybrids

This leucistic mutation is commonly mistaken for an albino.

There are several colour mutations of Indian peafowl. These very rarely occur in the wild, but selective breeding has made them common in captivity. The black-shouldered or Japanned mutation was initially considered as a subspecies of the Indian peafowl (P. c. nigripennis) (or even a separate species (P. nigripennis)) and was a topic of some interest during Darwin's time. Others had doubts about its taxonomic status, but the English naturalist and biologist Charles Darwin (1809–1882) presented firm evidence for it being a variety under domestication, which treatment is now well established and accepted. It being a colour variation rather than a wild species was important for Darwin to prove, as otherwise it could undermine his theory of slow modification by natural selection in the wild. It is, however, only a case of genetic variation within the population. In this mutation, the adult male is melanistic with black wings. Young birds with the nigripennis mutation are creamy white with fulvous-tipped wings. The gene produces melanism in the male and in the peahen it produces a dilution of colour with creamy white and brown markings. Other forms include the pied and white mutations, all of which are the result of allelic variation at specific loci.

 

Crosses between a male green peafowl (Pavo muticus) and a female Indian peafowl (P. cristatus) produce a stable hybrid called a "Spalding", named after Mrs. Keith Spalding, a bird fancier in California. There can be problems if birds of unknown pedigree are released into the wild, as the viability of such hybrids and their offspring is often reduced (see Haldane's rule and outbreeding depression).

 

Distribution and habitat

The Indian peafowl is a resident breeder across the Indian subcontinent and inhabits the drier lowland areas of Sri Lanka. In the Indian subcontinent, it is found mainly below an elevation of 1,800 m (5,900 ft) and in rare cases seen at about 2,000 m (6,600 ft). It is found in moist and dry-deciduous forests, but can adapt to live in cultivated regions and around human habitations and is usually found where water is available. In many parts of northern India, they are protected by religious practices and will forage around villages and towns for scraps. Some have suggested that the peacock was introduced into Europe by Alexander the Great, while others say the bird had reached Athens by 450 BCE and may have been introduced even earlier. It has since been introduced in many other parts of the world and has become feral in some areas.

 

The Indian peafowl has been introduced to the United States, the United Kingdom, United Arab Emirates, France, Mexico, Honduras, Costa Rica, Colombia, Guyana, Suriname, Brazil, Uruguay, Argentina, South Africa, Spain, Portugal, Greece, Italy, Madagascar, Mauritius, Réunion, Indonesia, Papua New Guinea, Australia, New Zealand, Croatia and the island of Lokrum.

 

Genome sequencing

The first whole-genome sequencing of Indian peafowl identified a total of 15,970 protein-coding sequences, along with 213 tRNAs, 236 snoRNAs, and 540 miRNAs. The peacock genome was found to have less repetitive DNA (8.62%) than that of the chicken genome (9.45%). PSMC analysis suggested that the peacock suffered at least two bottlenecks (around four million years ago and again 450,000 years ago), which resulted in a severe reduction in its effective population size.

 

Behaviour and ecology

Peafowl are best known for the male's extravagant display feathers which, despite actually growing from their back, are thought of as a tail. The "train" is in reality made up of the enormously elongated upper tail coverts. The tail itself is brown and short as in the peahen. The colours result not from any green or blue pigments but from the micro-structure of the feathers and the resulting optical phenomena. The long train feathers (and tarsal spurs) of the male develop only after the second year of life. Fully developed trains are found in birds older than four years. In northern India, these begin to develop each February and are moulted at the end of August. The moult of the flight feathers may be spread out across the year.

 

Peafowl forage on the ground in small groups, known as musters, that usually have a cock and 3 to 5 hens. After the breeding season, the flocks tend to be made up only of females and young. They are found in the open early in the mornings and tend to stay in cover during the heat of the day. They are fond of dust-bathing and at dusk, groups walk in single file to a favourite waterhole to drink. When disturbed, they usually escape by running and rarely take to flight.

 

Peafowl produce loud calls especially in the breeding season. They may call at night when alarmed and neighbouring birds may call in a relay like series. Nearly seven different call variants have been identified in the peacocks apart from six alarm calls that are commonly produced by both sexes.

 

Peafowl roost in groups during the night on tall trees but may sometimes make use of rocks, buildings or pylons. In the Gir forest, they chose tall trees in steep river banks. Birds arrive at dusk and call frequently before taking their position on the roost trees. Due to this habit of congregating at the roost, many population studies are made at these sites. The population structure is not well understood. In a study in northern India (Jodhpur), the number of males was 170–210 for 100 females but a study involving evening counts at the roost site in southern India (Injar) suggested a ratio of 47 males for 100 females.

 

Sexual selection

The colours of the peacock and the contrast with the much duller peahen were a puzzle to early thinkers. Charles Darwin wrote to Asa Gray that the "sight of a feather in a peacock's tail, whenever I gaze at it, makes me sick!" as he failed to see an adaptive advantage for the extravagant tail which seemed only to be an encumbrance. Darwin developed a second principle of sexual selection to resolve the problem, though in the prevailing intellectual trends of Victorian Britain, the theory failed to gain widespread attention.

 

The American artist Abbott Handerson Thayer tried to show, from his own imagination, the value of the eyespots as disruptive camouflage in a 1907 painting. He used the painting in his 1909 book Concealing-Coloration in the Animal Kingdom, denying the possibility of sexual selection and arguing that essentially all forms of animal colouration had evolved as camouflage. He was roundly criticised in a lengthy paper by Theodore Roosevelt, who wrote that Thayer had only managed to paint the peacock's plumage as camouflage by sleight of hand, "with the blue sky showing through the leaves in just sufficient quantity here and there to warrant the author-artists explaining that the wonderful blue hues of the peacock's neck are obliterative because they make it fade into the sky."

 

In the 1970s a possible resolution to the apparent contradiction between natural selection and sexual selection was proposed. Amotz Zahavi argued that peacocks honestly signalled the handicap of having a large and costly train. However, the mechanism may be less straightforward than it seems – the cost could arise from depression of the immune system by the hormones that enhance feather development.

  

Male courting female

The ornate train is believed to be the result of sexual selection by the females. Males use their ornate trains in a courtship display: they raise the feathers into a fan and quiver them. However, recent studies have failed to find a relation between the number of displayed eyespots and mating success. Marion Petrie tested whether or not these displays signaled a male's genetic quality by studying a feral population of peafowl in Whipsnade Wildlife Park in southern England. She showed that the number of eyespots in the train predicted a male's mating success, and this success could be manipulated by cutting the eyespots off some of the male's ornate feathers.

 

Although the removal of eyespots makes males less successful in mating, eyespot removal substantially changes the appearance of male peafowls. It is likely that females mistake these males for sub-adults, or perceive that the males are physically damaged. Moreover, in a feral peafowl population, there is little variation in the number of eyespots in adult males. It is rare for adult males to lose a significant number of eyespots. Therefore, females' selection might depend on other sexual traits of males' trains. The quality of train is an honest signal of the condition of males; peahens do select males on the basis of their plumage. A recent study on a natural population of Indian peafowls in the Shivalik area of India has proposed a "high maintenance handicap" theory. It states that only the fittest males can afford the time and energy to maintain a long tail. Therefore, the long train is an indicator of good body condition, which results in greater mating success. While train length seems to correlate positively with MHC diversity in males, females do not appear to use train length to choose males. A study in Japan also suggests that peahens do not choose peacocks based on their ornamental plumage, including train length, number of eyespots and train symmetry. Another study in France brings up two possible explanations for the conflicting results that exist. The first explanation is that there might be a genetic variation of the trait of interest under different geographical areas due to a founder effect and/or a genetic drift. The second explanation suggests that "the cost of trait expression may vary with environmental conditions," so that a trait that is indicative of a particular quality may not work in another environment.

 

Fisher's runaway model proposes positive feedback between female preference for elaborate trains and the elaborate train itself. This model assumes that the male train is a relatively recent evolutionary adaptation. However, a molecular phylogeny study on peacock-pheasants shows the opposite; the most recently evolved species is actually the least ornamented one. This finding suggests a chase-away sexual selection, in which "females evolve resistance to male ploys". A study in Japan goes on to conclude that the "peacocks' train is an obsolete signal for which female preference has already been lost or weakened".

 

However, some disagreement has arisen in recent years concerning whether or not female peafowl do indeed select males with more ornamented trains. In contrast to Petrie's findings, a seven-year Japanese study of free-ranging peafowl came to the conclusion that female peafowl do not select mates solely on the basis of their trains. Mariko Takahashi found no evidence that peahens expressed any preference for peacocks with more elaborate trains (such as trains having more ocelli), a more symmetrical arrangement, or a greater length. Takahashi determined that the peacock's train was not the universal target of female mate choice, showed little variance across male populations, and, based on physiological data collected from this group of peafowl, do not correlate to male physical conditions. Adeline Loyau and her colleagues responded to Takahashi's study by voicing concern that alternative explanations for these results had been overlooked, and that these might be essential for the understanding of the complexity of mate choice. They concluded that female choice might indeed vary in different ecological conditions.

 

A 2013 study that tracked the eye movements of peahens responding to male displays found that they looked in the direction of the upper train of feathers only when at long distances and that they looked only at the lower feathers when males displayed close to them. The rattling of the tail and the shaking of the wings helped in keeping the attention of females.

 

Breeding

Peacocks are polygamous, and the breeding season is spread out but appears to be dependent on the rains. Peafowls usually reach sexual maturity at the age of 2 to 3 years old. Several males may congregate at a lek site and these males are often closely related. Males at leks appear to maintain small territories next to each other and they allow females to visit them and make no attempt to guard harems. Females do not appear to favour specific males. The males display in courtship by raising the upper-tail coverts into an arched fan. The wings are held half open and drooped and it periodically vibrates the long feathers, producing a ruffling sound. The cock faces the hen initially and struts and prances around and sometimes turns around to display the tail. Males may also freeze over food to invite a female in a form of courtship feeding. Males may display even in the absence of females. When a male is displaying, females do not appear to show any interest and usually continue their foraging.

 

The peak season in southern India is April to May, January to March in Sri Lanka and June in northern India. The nest is a shallow scrape in the ground lined with leaves, sticks and other debris. Nests are sometimes placed on buildings and, in earlier times, have been recorded using the disused nest platforms of the white-rumped vultures. The clutch consists of 4–8 fawn to buff white eggs which are incubated only by the female. The eggs take about 28 days to hatch. The chicks are nidifugous and follow the mother around after hatching. Downy young may sometimes climb on their mothers' back and the female may carry them in flight to a safe tree branch. An unusual instance of a male incubating a clutch of eggs has been reported.

 

Feeding

Peafowl are omnivorous and eat seeds, insects (including termites), worms, fruits, small mammals, frogs, and reptiles (such as lizards). They feed on small snakes but keep their distance from larger ones. In the Gir forest of Gujarat, a large percentage of their food is made up of the fallen berries of Zizyphus. They also feed on tree and flower buds, petals, grain, and grass and bamboo shoots. Around cultivated areas, peafowl feed on a wide range of crops such as groundnut, tomato, paddy, chili and even bananas. Around human habitations, they feed on a variety of food scraps and even human excreta. In the countryside, it is particularly partial to crops and garden plants.

 

Mortality factors

Large animals such as leopards, dholes, golden jackals, and tigers can ambush adult peafowls. However, only leopards regularly prey upon peafowls as adult peafowls are difficult to catch since they can usually escape ground predators by flying into trees. They are also sometimes hunted by large birds of prey such as the changeable hawk-eagle and rock eagle-owl. Chicks are somewhat more prone to predation than adult birds. Adults living near human habitations are sometimes hunted by domestic dogs or by humans in some areas (southern Tamil Nadu) for folk remedies involving the use of "peacock oil".

 

Foraging in groups provides some safety as there are more eyes to look out for predators. They also roost on high tree tops to avoid terrestrial predators, especially leopards.

 

In captivity, birds have been known to live for 23 years but it is estimated that they live for only about 15 years in the wild.

 

Conservation and status

Indian peafowl are widely distributed in the wild across South Asia and protected both culturally in many areas and by law in India. Conservative estimates of the population put them at more than 100,000. Illegal poaching for meat, however, continues and declines have been noted in parts of India. Peafowl breed readily in captivity and as free-ranging ornamental fowl. Zoos, parks, bird-fanciers and dealers across the world maintain breeding populations that do not need to be augmented by the capture of wild birds.

 

Poaching of peacocks for their meat and feathers and accidental poisoning by feeding on pesticide treated seeds are known threats to wild birds. Methods to identify if feathers have been plucked or have been shed naturally have been developed, as Indian law allows only the collection of feathers that have been shed.

 

In parts of India, the birds can be a nuisance to agriculture as they damage crops. Its adverse effects on crops, however, seem to be offset by the beneficial role it plays by consuming prodigious quantities of pests such as grasshoppers. They can also be a problem in gardens and homes where they damage plants, attack their reflections (thereby breaking glass and mirrors), perch and scratch cars or leave their droppings. Many cities where they have been introduced and gone feral have peafowl management programmes. These include educating citizens on how to prevent the birds from causing damage while treating the birds humanely.

 

In culture

Prominent in many cultures, the peacock has been used in numerous iconic representations, including being designated the national bird of India in 1963. The peacock, known as mayura in Sanskrit, has enjoyed a fabled place in India since and is frequently depicted in temple art, mythology, poetry, folk music and traditions. A Sanskrit derivation of mayura is from the root mi for kill and said to mean "killer of snakes". It is also likely that the Sanskrit term is a borrowing from Proto-Dravidian *mayVr (whence the Tamil word for peacock மயில் (mayil)) or a regional Wanderwort. Many Hindu deities are associated with the bird, Krishna is often depicted with a feather in his headband, while worshippers of Shiva associate the bird as the steed of the God of war, Kartikeya (also known as Skanda or Murugan). A story in the Uttara Ramayana describes the head of the Devas, Indra, who unable to defeat Ravana, sheltered under the wing of peacock and later blessed it with a "thousand eyes" and fearlessness from serpents. Another story has Indra who after being cursed with a thousand ulcers was transformed into a peacock with a thousand eyes and this curse was removed by Vishnu.

 

In Buddhist philosophy, the peacock represents wisdom. Peacock feathers are used in many rituals and ornamentation. Peacock motifs are widespread in Indian temple architecture, old coinage, textiles and continue to be used in many modern items of art and utility. A folk belief found in many parts of India is that the peacock does not copulate with the peahen but that she is impregnated by other means. The stories vary and include the idea that the peacock looks at its ugly feet and cries whereupon the tears are fed on by the peahen causing it to be orally impregnated while other variants incorporate sperm transfer from beak to beak. Similar ideas have also been ascribed to Indian crow species. In Greek mythology the origin of the peacock's plumage is explained in the tale of Hera and Argus. The main figure of the Yazidi religion Yezidism, Melek Taus, is most commonly depicted as a peacock. Peacock motifs are widely used even today such as in the logos of the US NBC and the PTV television networks and the Sri Lankan Airlines.

 

These birds were often kept in menageries and as ornaments in large gardens and estates. In medieval times, knights in Europe took a "Vow of the Peacock" and decorated their helmets with its plumes. In several Robin Hood stories, the titular archer uses arrows fletched with peacock feathers. Feathers were buried with Viking warriors and the flesh of the bird was said to cure snake venom and many other maladies. Numerous uses in Ayurveda have been documented. Peafowl were said to keep an area free of snakes. In 1526, the legal issue as to whether peacocks were wild or domestic fowl was thought sufficiently important for Cardinal Wolsey to summon all the English judges to give their opinion, which was that they are domestic fowl.

 

In Anglo-Indian usage of the 1850s, to peacock meant making visits to ladies and gentlemen in the morning. In the 1890s, the term "peacocking" in Australia referred to the practice of buying up the best pieces of land ("picking the eyes") so as to render the surrounding lands valueless. The English word "peacock" has come to be used to describe a man who is very proud or gives a lot of attention to his clothing.

 

Main article: Di Goldene Pave

A golden peacock (in Yiddish, Di Goldene Pave) is considered by some as a symbol of Ashkenazi Jewish culture, and is the subject of several folktales and songs in Yiddish. Peacocks are frequently used in European heraldry. Heraldic peacocks are most often depicted as facing the viewer and with their tails displayed. In this pose, the peacock is referred to as being "in his pride". Peacock tails, in isolation from the rest of the bird, are rare in British heraldry, but see frequent use in German systems.

 

The American television network NBC uses a stylized peacock as a legacy of its early introduction of color television, alluding to the brilliant color of a peacock, and continues to promote the bird as a trademark of its broadcasting and streaming services.

Capable of producing 8,850 kilowatts, the Consumers Energy Croton hydroelectric plant, on the Muskegon River, began operating in 1907. With two units, Croton became the first facility in the world to transmit electricity at more than 110,000 volts. It was listed in the National Register of Historic Places on Aug. 16, 1979.

The Convair B-58 Hustler was the first operational supersonic jet bomber, and the first capable of Mach 2 flight. The aircraft was developed for the United States Air Force for service in the Strategic Air Command (SAC) during the 1960s. Originally intended to fly at high altitudes and speeds to avoid Soviet fighters, the introduction of highly accurate Soviet surface-to-air missiles forced the B-58 into a low-level penetration role that severely limited its range and strategic value. This led to a brief operational career between 1960 and 1969. Its specialized role was succeeded by other American supersonic bombers, such as the FB-111A and the later B-1B Lancer.

 

The B-58 received a great deal of notoriety due to its sonic boom, which was often heard by the public as it passed overhead in supersonic flight.

 

This aircraft flew from Los Angeles to New York and back on 5 March 1962, setting three separate speed records, and earning the crew the Bendix Trophy and the Mackay Trophy for 1962. The aircraft was flown to the Museum on 1 March 1969.

The F-105 Thunderchief, which would become a legend in the history of the Vietnam War, started out very modestly as a proposal for a large, supersonic replacement for the RF-84F Thunderflash tactical reconnaissance fighter in 1951. Later this was expanded by Republic’s famous chief designer, Alexander Kartveli, to a nuclear-capable, high-speed, low-altitude penetration tactical fighter-bomber which could also replace the F-84 Thunderstreak.

 

The USAF liked the idea, as the F-84 had shown itself to be at a disadvantage against Chinese and Soviet-flown MiG-15s over Korea, and ordered 200 of the new design before it was even finalized. This order was reduced to only 37 aircraft with the end of the Korean War, but nonetheless the first YF-105A Thunderchief flew in October 1955. Although it was equipped with an interim J57 engine and had drag problems, it still achieved supersonic speed. When the design was further refined as the YF-105B, with the J75 engine and area ruling, it went over Mach 2. This was in spite of the fact that the design had mushroomed in size from Kartveli’s initial idea to one of the largest and heaviest fighter ever to serve with the USAF: fully loaded, the F-105 was heavier than a B-17 bomber. The USAF ordered 1800 F-105s, though this would be reduced to 830 examples.

 

Almost immediately, the F-105 began to be plagued with problems. Some of the trouble could be traced to the normal teething problems of any new aircraft, but for awhile it seemed the Thunderchief was too hot to handle, with a catastrophically high accident rate. This led to the aircraft getting the nickname of “Thud,” supposedly for the sound it made when hitting the ground, along with other not-so-affectionate monikers such as “Ultra Hog” and “Squat Bomber.” Despite its immense size and bad reputation, however, the F-105 was superb at high speeds, especially at low level, was difficult to stall, and its cockpit was commended for its ergonomic layout. Earlier “narrow-nose” F-105Bs were replaced by wider-nosed, radar-equipped F-105Ds, the mainline version of the Thunderchief, while two-seat F-105Fs were built as conversion trainers.

 

Had it not been for the Vietnam War, however, the F-105 might have gone down in history as simply another 1950s era mildly successful design. Deployed to Vietnam at the beginning of the American involvement there in 1964, the Thunderchief was soon heading to North Vietnam to attack targets there in the opening rounds of Operation Rolling Thunder; this was in spite of the fact that the F-105 was designed primarily as a low-level (and, as its pilots insisted, one-way) tactical nuclear bomber. Instead, F-105s were heading north festooned with conventional bombs.

 

As Rolling Thunder gradually expanded to all of North Vietnam, now-camouflaged Thuds “going Downtown” became iconic, fighting their way through the densest concentration of antiaircraft fire in history, along with SAMs and MiG fighters. The F-105 now gained a reputation for something else: toughness, a Republic hallmark. Nor were they defenseless: unlike the USAF’s primary fighter, the F-4 Phantom II, the F-105 retained an internal 20mm gatling cannon, and MiG-17s which engaged F-105s was far from a foregone conclusion, as 27 MiGs were shot down by F-105s for the loss of about 20. If nothing else, Thud pilots no longer burdened with bombs could simply elect to head home at Mach 2 and two thousand feet, outdistancing any MiG defenders.

 

If the Thud had any weakness, it was its hydraulic system, which was found to be extremely vulnerable to damage. However, it was likely more due to poor tactics and the restrictive Rules of Engagement, which sent F-105s into battle on predictable routes (namely from the northeast, down the Red River Valley to Hanoi and over Tam Do Mountain—renamed by American pilots “Thud Ridge”), unable to return fire on SAM sites until missiles were launched at them, and their F-4 escorts hamstrung by being forced to wait until MiGs were on attack runs before engaging them. The tropical climate also took a toll on man and machine, with the end result that 382 F-105s were lost over Vietnam, nearly half of all Thuds ever produced and the highest loss rate of any USAF aircraft.

 

The combination of a high loss rate and the fact that the F-105 really was not designed to be used in the fashion it was over Vietnam led to the type’s gradual withdrawal after 1968 in favor of more F-4s and a USAF version of the USN’s A-7 Corsair II. An improved all-weather bombing system, Thunderstick II, was given to a few of the F-105D survivors, but this was not used operationally. The Thud soldiered on another decade in Air National Guard and Reserve units until February 1984, when the type was finally retired in favor of the F-16, and its spiritual successor, the A-10 Thunderbolt II.

 

Dad got to be friends with a well-known Thud pilot of the Vietnam War, Ben Allen. Allen, a native of Texas, flew one of the first camouflaged F-105s on his tour and named his bird the "Lone Star Special." Dad built Allen a 1/48 scale model of his F-105, which Dad regarded as a challenge, as it would require painting it in "reverse camouflage." Allen's Thud was painted in the correct Southeast Asia pattern worn by F-105s after 1966, but for some reason the colors were applied in reverse--greens where browns were normally used, and vice-versa. A few other F-105s were painted in this fashion as well.

 

"The Lone Star Special" is configured for working against surface-to-air missile sites, with six Mk 84 750-pound bombs, two external fuel tanks, an AGM-45 Shrike antiradar missile, and an ALQ-87 electronic countermeasures pod. Allen flew before tailcodes were adopted in Vietnam, so it only carries a tail number. Allen completed his 100 missions and came home safely, but 61-0140 was not as lucky. It was shot down on 7 August 1966 near Hanoi; the pilot ejected, was captured, and finished the war as a POW. The model is, to the best of my knowledge, still in the possession of Mr. Allen.

First time seeing the very capable AT-802 alive and running. Not just the one but three were in action.

 

Wednesday the 6th of March saw quite a bit of movement out of the Mansfield DELWP Fire Bombing base. Amongst the movements, Bombers 352, 353 (Field Air) and 358 (Pays) were busy making runs out to the various fires in the region.

Young Grebes are capable of swimming and diving almost after hatching.The adult teach these skills to their young by carrying them at their back and diving,leaving the chicks to float on the surface,they then re-emerge a few feet away,so that the chicks may swim back onto them.

The red wasp is a social insect, with each nest occupied by a single queen that lays eggs and similar looking female workers who are her daughters. Males, born only later in the season, perform the sole duty of mating with future queens.

 

Red wasps are considered beneficial because they consume caterpillars. The adults actually eat nectar from flowers, but they spend much of their time hunting in order to feed the grubs developing in their nest. If a wasp finds a caterpillar that is too large to carry away, it will cut it up on the spot and sometimes eat some and carry back just a portion to the nest. The bits of flesh are chewed up before being fed to the developing grubs. It is surprising how quickly the wasps are capable of disposing of a caterpillar after they locate it.

 

The females are capable of giving a painful sting but males cannot, as the stinger is actually a modified ovipositor. While red wasps are not particularly aggressive, they tend to build their nests in hidden locations and will sting when these are disturbed.

Jumping spider

 

The jumping spider family (Salticidae) contains more than 500 described genera and about 5,000 described species, making it the largest family of spiders with about 13% of all species. Jumping spiders have some of the best vision among arthropods and use it in courtship, hunting, and navigation. Although they normally move unobtrusively and fairly slowly, most species are capable of very agile jumps, notably when hunting, but sometimes in response to sudden threats. Both their book lungs and the tracheal system are well-developed, and they use both systems (bimodal breathing). Jumping spiders are generally recognized by their eye pattern. All jumping spiders have four pairs of eyes with one pair being their particularly large anterior median eyes.

  

Distinguishing characteristics

 

Jumping spiders are among the easiest to distinguish from similar spider families because of the shape of the cephalothorax and their eye patterns. The families closest to Salticidae in general appearance are the Corinnidae (distinguished also by prominent spines on the back four legs), the Oxyopidae (the lynx spiders, distinguished by very prominent spines on all legs), and the Thomisidae (the crab spiders, distinguished by their front four legs, which are very long and powerful). None of these families however, has eyes that resemble those of the Salticidae. Conversely, the legs of jumping spiders are not covered with any very prominent spines. Their front four legs generally are larger than the hind four, but not as dramatically so as those of the crab spiders, nor are they held in the outstretched-arms attitude characteristic of the Thomisidae. In spite of the length of their front legs, Salticidae depend on their rear legs for jumping. The generally larger front legs are used partly to assist in grasping prey, and in some species, the front legs and pedipalps are used in species-recognition signalling.

 

The jumping spiders, unlike the other families, have faces that are roughly rectangular surfaces perpendicular to their direction of motion. In effect this means that their forward-looking, anterior eyes are on "flat faces", as shown in the photographs. Their eye pattern is the clearest single identifying characteristic. They have eight eyes. Most diagnostic are the front row of four eyes, in which the anterior median pair are more dramatically prominent than any other spider eyes apart from the posterior median eyes of the Deinopidae. There is, however, a radical functional difference between the major (AME) eyes of Salticidae and the major (PME) eyes of the Deinopidae; the large posterior eyes of Deinopidae are adapted mainly to vision in dim light, whereas the large anterior eyes of Salticidae are adapted to detailed, three-dimensional vision for purposes of estimating the range, direction, and nature of potential prey, permitting the spider to direct its attacking leaps with great precision. The anterior lateral eyes, though large, are smaller than the AME and provide a wider forward field of vision.

 

The rear row of four eyes may be described as strongly bent, or as being rearranged into two rows, with two large posterior lateral eyes furthest back. They serve for lateral vision. The posterior median eyes also have been shifted out laterally, almost as far as the posterior lateral eyes. They are usually much smaller than the posterior lateral eyes and there is doubt about whether they are at all functional in many species.

Jumping spiders range in size from a body length of 1 to 22 mm.

 

In addition to using their silk for safety lines while jumping, they also build silken "pup tents", where they shelter from bad weather and sleep at night. They molt within these shelters, build and store egg cases within them, and also spend the winter in them

  

Vision

 

Jumping spiders have four pairs of eyes; three secondary pairs that are fixed and a principal pair that is movable.

 

The posterior median eyes (PME) are vestigial in many species, but in some primitive sub-families they are comparable in size with the other secondary eyes and help to detect motion.

 

The posterior lateral eyes (PLE) are wide-angle motion detectors which sense motions from the side and behind. Combined with the other eyes, it gives the spider a near 360-degree view of the world.

 

The anterior lateral eyes (ALE) have the best visual acuity and are the most complex of the secondary eyes.[9] It has been shown that they are able to distinguish some details as well, and without them no "looming response" will be triggered by motion.[10] Even with all the other pairs covered, jumping spiders in a study could still detect, stalk and attack flies, using the anterior lateral eyes only, which are also sufficiently widely spaced to provide stereoscopic vision.

 

The anterior median eyes (AME) have very good vision. This pair of eyes is built like a telescopic tube with a corneal lens in the front and a second lens in the back that focus images onto a four-layered retina, a narrow boomerang-shaped strip oriented vertically. Physiological experiments have shown they may have up to four different kinds of receptor cells, with different absorption spectra, giving them the possibility of up to tetrachromatic color vision, with sensitivity extending into the ultraviolet range. As the eyes are too close together to allow depth perception, and the animals do not make use of motion parallax, they have evolved a method called image defocus instead. Of the four photoreceptor layers in the retina, the first two closest to the surface contain ultraviolet-sensitive pigments while the two deepest contain green-sensitive pigments. The incoming green light is only focused on the deepest layer, while the other one receives defocused or fuzzy images. By measuring the amount of defocus from the fuzzy layer, it is possible to calculate the distance to the objects in front of them. In addition to receptor cells, also red filters have been detected, located in front of the cells that normally register green light. It seems that all salticids, regardless of whether they have two, three, or four kinds of color receptors, are highly sensitive to UV light. Some species (for example, Cosmophasis umbratica) are highly dimorphic in the UV spectrum, suggesting a role in sexual signaling (Lim & Li, 2005). Color discrimination has been demonstrated in behavioral experiments.

 

The principal, anterior median, eyes have high resolution (11 min visual angle), but the field of vision is narrow, from 2 to 5°. The central region of the retina, where acuity is highest, is no more than six or seven receptor rows wide. However, the eye can scan objects off the direct axis of vision. As the lens is attached to the carapace, the eye's scanning movements are restricted to its retina through a complicated pattern of translations and rotations. This dynamic adjustment is a means of compensation for the narrowness of the static field of vision. It is analogous to the way most primates move their eyes to focus images of interest onto the fovea centralis. Such movements within the jumping spider's eyes are visible from outside when the attention of the spider is directed to various targets.

  

Behavior

 

Jumping spiders are generally diurnal, active hunters. Their well-developed internal hydraulic system extends their limbs by altering the pressure of body fluid (hemolymph) within them. This enables the spiders to jump without having large muscular legs like a grasshopper. Most jumping spiders can jump several times the length of their bodies. When a jumping spider is moving from place to place, and especially just before it jumps, it tethers a filament of silk (or 'dragline') to whatever it is standing on to protect itself if the jump should fail. Should it fall, for example if the prey shakes it off, it climbs back up the silk tether. Some species, such as Portia, will actually let themselves down to attack prey such as a web spider apparently secure in the middle of its web. Like many other spiders that leave practically continuous silk trails, jumping spiders impregnate the silk line with pheromones that play a role in social and reproductive communication, and possibly in navigation.

 

Certain species of jumping spiders have been shown by experiment to be capable of learning, recognizing, and remembering colors, and adapting their hunting behavior accordingly.

  

Hunting

 

The hunting behaviour of the Salticidae is confusingly varied compared to that of most spiders in other families. Salticids hunt diurnally as a rule, which is consistent with their highly developed visual system. When it detects potential prey, a jumping spider typically begins orienting itself by swivelling its cephalothorax to bring the anterior median eyes to bear. It then moves its abdomen into line with its cephalothorax. After that, it might spend some time inspecting the object of its attention and determining whether a camouflaged or doubtful item of prey is promising, before it starts to stalk slowly forward. When close enough, the spider pauses to attach a dragline, then springs onto the prey.

 

There are, though, many variations on the theme and many surprising aspects. For one thing, salticids do not necessarily follow a straight path in approaching prey. They may follow a circuitous course, sometimes even a course that takes the hunter through regions from which the prey is not visible. Such complex adaptive behaviour is hard to reconcile with an organism that has such a tiny brain, but some jumping spiders, in particular some species of Portia, can negotiate long detours from one bush down to the ground, then up the stem of another bush to capture a prey item on a particular leaf. Such behaviour still is the subject of research.

 

Some salticid species are continually on the move, stopping periodically to look around for prey, which they then stalk immediately. Others spend more time scanning their surroundings from one position, actively stalking any prey they detect. Members of the genus Phaeacius take that strategy to extremes; they sit on a tree trunk, facing downwards and rarely do any stalking, but simply lunge down on any prey items that pass close before them.

 

Some Salticidae specialise in particular classes of prey. Ants comprise one such class. Most spiders, including most salticids, avoid worker ants, but several species not only eat them as a primary item in their diets, but also employ specialised attack techniques — Corythalia canosa for example, circles round to the front of the ant and grabs it over the back of its head. Such myrmecophagous species, however, will not necessarily refuse other prey items, and will routinely catch flies and similar prey in the usual salticid fashion, without the special precautions they apply in hunting dangerous prey such as ants. Ants offer the advantages of being plentiful prey items for which there is little competition from other predators, but it remains profitable to catch less hazardous prey when it presents itself.

 

Some of the most surprising hunting behaviour occurs among the araneophagous Salticidae, and it varies greatly in method. Many of the spider-hunting species quite commonly will attack other spiders, whether fellow salticids or not, in the same way as any other prey, but some kinds resort to web invasion; nonspecialists such as Phidippus audax sometimes attack prey ensnared in webs, basically in acts of kleptoparasitism — sometimes they leap onto and eat the web occupant itself, or simply walk over the web for that purpose.

 

Salticidae in the genera Brettus, Cyrba, Gelotia, and Portia display more advanced web-invasion behavior. They slowly advance onto the web and vibrate the silk with their pedipalps and legs. In this respect, their behaviour resembles that of the Mimetidae, probably the most specialised of the araneophagous spider families. If the web occupant approaches in the manner appropriate to dealing with ensnared prey, the predator attacks.

 

The foregoing examples present the Salticidae as textbook examples of active hunters; they would hardly seem likely to build webs other than those used in reproductive activities, and in fact, most species really do not build webs to catch prey. However, exceptions occur, though even those that do build capture webs generally also go hunting like other salticids. Some Portia species, for example, spin capture webs that are functional, though not as impressive as some orb webs of the Araneidae; Portia webs are of an unusual funnel shape and apparently adapted to the capture of other spiders. Spartaeus species, on the other hand, largely capture moths in their webs. In their review of the ethology of Salticidae, Richman and Jackson speculate on whether such web building is a relic of the evolution of this family from web-building ancestors.

In hunting, Salticidae also use their silk for a tether to enable them to reach prey that otherwise would be inaccessible. For example, by advancing towards the prey to less than the jumping distance, then retreating and leaping in an arc at the end of the tether line, many species can leap onto prey on vertical or even on inverted surfaces, which of course in a gravitational field would not be possible without such a tether.

Having made contact with the prey, hunting Salticidae administer a bite to inject rapidly acting venom that gives the victim little time to react. In this respect, they resemble the Mimetidae and Thomisidae, families that ambush prey that often are larger than the predator, and they do so without securing the victim with silk; they accordingly must immobilise it immediately and their venom is adapted accordingly.

  

Diet

 

Although jumping spiders are generally carnivorous, many species have been known to include nectar in their diets, and one species, Bagheera kiplingi, feeds primarily on plant matter. None is known to feed on seeds or fruit. Extrafloral nectaries on plants, such as the partridge pea, provide jumping spiders with nectar; the plant benefits accordingly when the spiders prey on whatever pests they find.

  

Reproduction

 

Jumping spiders use their vision in complex visual courtship displays. Males are often quite different in appearance from females, and may have plumose hairs, colored or iridescent hairs, front leg fringes, structures on other legs, and other, often bizarre, modifications. These are used in visual courtship in which the colored or iridescent parts of the body are displayed and complex sideling, vibrational, or zigzag movements are performed in a courtship "dance". If the female is receptive to the male, she will assume a passive, crouching position. In some species, the female may also vibrate her palps or abdomen. The male will then extend his front legs towards the female to touch her. If the female remains receptive, the male will climb on the female's back and inseminate her with his palps.

 

A 2008 study of the species Phintella vittatain in Current Biology suggests female spiders react to the males reflecting ultraviolet B light before mating, a finding that challenges the previously held assumption that animals did not register ultraviolet B light. It has recently been discovered that many jumping spiders seem to have auditory signals as well; amplified sounds produced by the males resemble buzzes or drum rolls.

  

Taxonomy and systematics

 

The monophyly of the family Salticidae is well established through both phylogenetic and morphological analyses, but no consensus exists on what other group of spiders are most closely related to the jumping spiders. Suggested sister groups have included the oxyopids (lynx spiders), thomisids (crab spiders), clubionoids (sac spiders), and web-building spiders.

 

Jumping spiders can be divided into three major lineages: the lyssomanines (subfamily Lyssomaninae), the spartaeines (subfamily Spartaeinae), and the salticoids (unranked clade Salticoida). Of these, the Salticoida account for over 90% of all jumping spider species. Salticoida can be further divided into numerous groups, including Amycoida, Astioida, Aelurilloida, Euophryinae, Heliophaninae, Marpissoida, and Plexippoida.

Models for mimicry

 

Some small insects are thought to have evolved an appearance or behavioural traits that resemble those of jumping spiders and this is suspected to prevent their predation, specifically from jumping spiders. Some examples appear to be provided by patterns on the wings of some Tephritid flies, nymph of a Fulgorid and possibly some moths.

  

Fossils

 

Very few jumping spider fossils have been found. Of those known, all are from Cenozoic era amber. The oldest fossils are from Baltic amber dating to the Eocene epoch, specifically, 54 to 42 million years ago. Other fossil jumping spiders have been found in Chiapan amber and Dominican amber.

The Harrier, informally referred to as the Jump Jet, is a family of military jet aircraft capable of vertical/short takeoff and landing (V/STOL) operations.

 

Historically the Harrier was developed in Britain to operate from ad-hoc facilities such as car parks or forest clearings, avoiding the need for large air bases vulnerable to tactical nuclear weapons. Later the design was adapted for use from aircraft carriers.

 

The Harrier is also distinct as being of the modern era, yet subsonic, contrasting with most of the major Western post-World War II-era attack aircraft, which tend to be supersonic.

 

The Vought F4U Corsair was a carrier-capable fighter aircraft that saw service primarily in World War II and the Korean War.

 

The Corsair served in the U.S. Navy, U.S. Marines and the U.S. navy., Fleet Air Arm, quickly becoming the most capable carrier-based fighter-bomber of World War II.

 

Some Japanese pilots reportedly regarded it as the most formidable American fighter of World War II, and the U.S. Navy counted an 11:1 kill ratio with the F4U Corsair.

 

As well as being an outstanding fighter, the Corsair proved to be an excellent fighter-bomber, serving almost exclusively in the latter role throughout the Korean War and during the French colonial wars in Indochina and Algeria.

 

The National Museum of the Marine Corps in Triangle (VA) is situated on a 135-acre site adjacent to the Marine Corps Base at Quantico, and is under the command of the Marine Corps University.

The Belfast was developed to meet a Royal Air Force operational requirement (ASR.371) for a freighter capable of carrying a wide range of military loads over long ranges. The military loads envisaged included artillery, more than 200 troops, helicopters, and guided missiles. Shorts' design was based on studies they had worked on in the late 1950s and the project started as the SC.5/10 in February 1959. From that design, the prototype Belfast first flew on 5 January 1964.

 

The Belfast was notable for being only the second aircraft type to be built equipped with autoland blind landing equipment.

 

To meet the demands of the specification the Belfast used a high wing carrying four Rolls-Royce Tyne turboprops. The cargo deck, 64 ft long (20 m) in a fuselage over 18 ft in diameter (5.5 m) (roomy enough for two single-deck buses), was reached through a "beaver tail" with rear loading doors and integral ramp. The main undercarriage was two 8-wheel bogies and a 2-wheel nose. The Belfast was capable of a maximum takeoff weight (MTOW) of over 220,500 lb (100 tonnes) - less than the contemporaneous 250-tonne Antonov An-22 and the 128-tonne Douglas C-133 Cargomaster, but more than the C-130 Hercules. It could carry 150 troops with full equipment, or a Chieftain tank or two Westland Wessex helicopters or six Westland Scout helicopters.

 

The original RAF requirement had foreseen a fleet of 30 aircraft, but this number was to be significantly curtailed as a result of the Sterling Crisis of 1965. The United Kingdom government needed to gain support for its loan application to the International Monetary Fund, which the United States provided. However, one of the alleged clauses for this support was that the RAF purchase Lockheed C-130 Hercules aircraft. With a surplus of airlifting capacity the original order was reduced to 10. The Belfast entered service with No. 53 Squadron RAF in January 1966 based at RAF Fairford. By May the following year they had been moved to RAF Brize Norton.

 

Following entry to RAF service it became apparent that a major drag problem was preventing the initial five aircraft attaining Short’s desired performance. Suction drag on the tail and rear fuselage was so severe that the RAF personnel gave the aircraft the nicknames "The Dragmaster", "Slug" and "Belslow". Modifications and testing were carried out, particularly on aircraft SH1818 (which was at the time perfecting the RAF’s requirement for CAT 3 automated landings at RAE Bedford) and a new rear fairing was built improving the fleet’s cruising speed by 40 mph.

 

The reorganisation of the new RAF Strike Command was to have repercussions on the RAF’s Belfast fleet and ushered in the retirement of a number of aircraft types, including the Bristol Britannia and De Havilland Comet in 1975. By the end of 1976 the Belfast fleet had been retired and flown to RAF Kemble for storage.

 

TAC HeavyLift then purchased five of them for commercial use in 1977 and operated three of them from 1980 after they had received work so they could be certificated to civil standards. Ironically, some of them were later chartered during the Falklands war, with some sources suggesting that this cost more than keeping all the aircraft in RAF service until the 1990s. HeavyLift's Belfasts were again contracted to support the RAF during the first Gulf War, transporting vehicles and helicopters too large to be carried by the Hercules fleet.

    

History Of The Gatlin Guns

 

In 1861, Doctor Richard Gatling patented the Gatling Gun, a six-barreled weapon capable of firing a (then) phenomenal 200 rounds per minute. The Gatling gun was a hand-driven, crank-operated, multi-barrel, machine gun. The first machine gun with reliable loading, the Gatling gun had the ability to fire sustained multiple bursts.

 

Richard Gatling created his gun during the American Civil War, he sincerely believed that his invention would end war by making it unthinkable to use due to the horrific carnage possible by his weapons.

 

At the least, the Gatling Gun's power would reduce the number of soldiers required to remain on the battlefield.

 

The 1862 version of the gatling gun had reloadable steel chambers and used percussion caps. It was prone to occasional jamming. In 1867, Gatling redesigned the Gatling gun again to use metallic cartridges - this version was bought and used by the United States Army.

  

Born September 12, 1818 in Hertford Count, North Carolina, Richard Gatling was the son of planter and inventor, Jordan Gatling, who held two patents of his own. Besides the Gatling gun, Richard Gatling also patented a seed-sowing rice planter in 1839 that was later adapted into a successful wheat drill.

 

In 1870, Richard Gatling and his family moved to Hartford, Connecticut, home of the Colt Armory where the Gatling gun was being manufactured.

GATLIN 4x20 kilowatt laser cannon

 

The ultimate laser cannon:

 

'Gatling gun' can focus multiple beams to create super powerful weapons

Demonstration showed four 20 kilowatt lasers fire simultaneously.German firm behind it says an 'unlimited' number can be combined.Expected to initially be used to shoot drones out of the sky

 

A German firm has revealed a powerful new laser 'gatling gun'.At the controversial defense and security expo in London German defense contractor Rheinmetall Defense Electronics unveiled the new sea based system.It says it can be mounted on ships as part of a new sea-based anti-drone laser system.

 

The four 20 kilowatt lasers fire simultaneously as a single powerful 80 kilowatt beam. The firm boasts units can even be combined for 'unlimited' power.

HOW IT WORKS

 

The four 20 kilowatt lasers fire simultaneously, in a technique known as superimposition which combines them into a single powerful 80 kilowatt beam.

 

The firm boasts units can even be combined to give 'unlimited' power.

The four 20 kilowatt lasers fire simultaneously, in a technique known as superimposition which combines them into a single powerful 80 kilowatt beam.

 

The Gatling laser can reportedly shoot down a drone at 500 meters.

 

Lasers can also detonate ammunition, explode artillery shells, blind the sensors of another ship, and even burn holes in smaller ships.

 

The firm boasts units can even be combined to give 'unlimited' power.

 

'The beam-forming unit provides diffraction-limited beam focusing, target imaging and fine tracking of the target,' it said.

 

'By using beam-superimposing technology, Rheinmetall has concentrated the power of single laser beams into one tiny spot.

 

This technology not only allows superimposition of multiple laser beams on a single gun platform, but also superimposition of multiple gun platforms.

 

'This enables an almost unlimited (e.g. 100kW and more) power output in line with the evolving air defence requirement.

 

At the London show, the firm demonstrated an Oerlikon Skyshield turret with integrated HELeffector as well as a newly developed powerful HEL effector for naval applications.

 

'Highly precise, scalable in effect, versatile in tactical situations, ready for deployment on land and at sea - high energy laser effectors will play a major role in future armament concepts,' the firm says

'With its unique concept of multiple high-energy laser beams superimposed and focused on one spot on the target, Rheinmetall leads the way among European defence contractors in this new field,' the firm said.

 

'After six years of continuously demonstrating a growing capability, a new Rheinmetall air defence application has emerged that is attracting interest worldwide - shooting drones.'

 

Dubbed the low, slow and small (LSS) threat, it has huge potential to create a highly unbalanced situation between conventional defenders and mainly asymmetrically operating attackers.

 

New missions, such as the defence of high visibility events, pose unsolved challenges for contemporary air defence systems that will only be manageable with high energy lasers serving as effectors.

 

The Gatling laser can reportedly shoot down a drone at 500 meters.

 

It uses an Oerlikon Skyshield or Skyguard fire control unit for target acquisition and weapon control, coupled with an Oerlikon highenergy laser gun using a revolver gun turret equipped with HEL effectors.Each HEL effector consists of one 10 kW fibre laser and a beam-forming unit.Commercial off the-shelf fibre lasers were modified for an air defence role. Variants of the same technology are also available for ground and naval operations.

 

The Samsung Omnia HD i8910 is mobile phones that have a razor sharp amoled display (16M color) with a set of multimedia features. This device is capable of capturing 720p HD-like video and 8 megapixel quality pictures plus with 8 /16GB built-in memory and it is also comes with a smart phone abilities.

Physically, Samsung Omnia HD i8910 is narrower than the iPhone but definitely it is better than over most mobile phone. Surprisingly, the thickness of Samsung Omnia HD i8910 is only 12.9mm and its weight is 149 gram but I still found it was comfortable to hold and operate it with one hand.

Omnia HD i8910 screen size is 3.7 inches diagonally with a 360 x 640 pixel (Touchscreen) and it comes with amoled displays. Amoled displays are the future of video displays where the colours jump off the screen so what you see is intensified, ultra wide viewing and superior brightness means you can read it in sunlight. Its screen dominates the entire front panel and its have only 3 self explanatory keys.

Omnia HD i8910 is the world’s first mobile phone with a real HD video camera built-in and if you shooting a video using Omnia HD i8910 you can realize that it can beat over any possible competition, even Nikon D1 recording video doesn’t come close to it. Comparatively, Omnia HD i8910 has three times more resolution than Nikon D1.

Omnia HD i8910 also comes with an 8-megapixel auto focus camera with LED flash, geo-tagging, face detection, Smile Shot, Blink Shot and panorama mode. The image output was awesome compared to other camera phone but the image looked well on the phone compared to when viewed on computer.
