The heat and rain have enabled the mosquitos to breed prolifically. Each night about 6.30 we need to light the citronella candles to deter them from coming inside.
Not quite sure why I like this farm building, but I was quite taken with it. I think it's the clean lines and simplicity. The building is typical of the area, very plain and simple, and in their way quite stylish. They have to withstand the most extreme weather (note the colour of the sky) and be earthquake proof. The landscape is very bleak with no large trees, the tallest trees we saw were perhaps 2m, and skinny spindly things. Anything with any substance would be uprooted fairly fast in the frequent powerful winds.
The European Space Agency’s mission to discover Earth-like exoplanets, Plato, is now sealed in the Large Space Simulator (LSS) chamber at ESA’s Test Centre for a series of vital tests under space‑like conditions.
Engineers placed Plato in the LSS on 18 February, and since the beginning of March the spacecraft has been experiencing the extreme temperatures and vacuum of space. This photo captures the satellite standing in the centre of the simulator, moments before the chamber was bolted closed.
The picture was taken from the top opening of the LSS and gives us a direct view of Plato’s 26 ultrasensitive cameras. These are the special eyes that the mission will use to monitor more than 150 000 bright stars at the same time, hunting for terrestrial planets orbiting Sun-like stars.
The mission is expected to be ready for launch by the end of the year. Liftoff on an Ariane 6 is planned by Arianespace for January 2027.
But before launching a spacecraft, it is crucial to operate it and check all its functionalities in a space-like environment. The LSS offers just that.
A cylindrical container standing 15 m high and 10 m wide, the LSS is Europe's largest cryovacuum chamber. Equipped with a high-performance pump, the enclosure achieves a pressure a billion times lower than the sea-level atmospheric pressure, while liquid nitrogen circulating around its casing reproduces the extreme low temperatures of space.
Exposed to a grid of powerful heating elements (so-called ‘calrods’) that simulate the heat of the Sun, the backside of the spacecraft – with solar panels and sunshield – reaches a toasty 160 °C. At the same time, thanks to the sunshield and excellent insulation, the cameras and the optical bench facing the dark, cold part of the chamber are kept very cool at around –80 °C, as if facing deep space.
Plato will reemerge from the space simulator at the end of March.

On top of the spacecraft, we see the blue, shiny lenses of 26 large cameras. The cameras are mounted on a five‑stepped platform and arranged in four rows of six cameras, plus a top row with two cameras.]

With a simple pull of the lever, these decorative figures can open and close their jaws like authentic nutcrackers!
Both of these models were built in the recent weeks leading up to Christmas. The design was pretty straightforward, but two major issues were making the faces look good, and finally getting the hats right. In fact, the green nutcracker's crown took the longest to figure out, and was finally made with hinge plates.
As mentioned in the tutorial, although these can in fact function as real nutcrackers, they're somewhat rickety and best suited for holiday decorations.
Kmart #7120 opened on 9/9/1976 in a former Grant City store. This store was the last Kmart to have a fully functional restaurant in it. This Kmart ended up closing in September 2017.
I highlighted in my photo titled "Pass the Parcel - 2" that in Autumn 2015, Pembrokeshire County Council took on the lease of a Plaxton Centro-bodied VDL SB200 for contracted Service 322 (Haverfordwest & Withybush Hospital-Narberth-Whitland-St Clears-Carmarthen & Glangwili Hospital) on behalf of the then contractor, Silcox.
Silcox had been regularly using a UVG-bodied Dennis Javelin, P780 WDE, on the contract, which had replaced an 08-plate Alexander Dennis Enviro300. January 2016 was the deadline for single-deck service buses used on registered local bus services to comply with the Public Service Vehicle Accessibility Regulations 2000 (PSVAR), which no doubt prompted the Council's actions in leasing the VDL.
Whilst Silcox had built up a sizeable fleet of former MoD vehicles, P780 WDE had been purchased new, presumably as as a cheaper option than a buying a standard coach.

The Volkswagen Beetle (officially the Volkswagen Type 1, informally in Germany the Volkswagen Käfer, in Poland the Volkswagen Garbus and in the U.S. the Volkswagen Bug) is a two-door, four passenger, rear-engine economy car manufactured and marketed by German automaker Volkswagen (VW) from 1938 until 2003.
The need for this kind of car, and its functional objectives, was formulated by the leader of Nazi Germany, Adolf Hitler, who wanted a cheap, simple car to be mass-produced for his country's new road network. Hitler contracted Ferdinand Porsche in 1934 to design and build it. Porsche and his team took until 1938 to finalise the design. The influence on Porsche's design of other contemporary cars, such as the Tatra V570 and the work of Josef Ganz remains a subject of dispute. The result was one of the first rear-engined cars since the Brass Era. With 21,529,464 produced, the Beetle is the longest-running and most-manufactured car of a single platform ever made.
Although designed in the 1930s, the Beetle was only produced in significant numbers from 1945 on (mass production had been put on hold during the Second World War) when the model was internally designated the Volkswagen Type 1, and marketed simply as the Volkswagen (or "People's Car"). Later models were designated Volkswagen 1200, 1300, 1500, 1302 or 1303, the former three indicating engine displacement, the latter two derived from the type number. The model became widely known in its home country as the Käfer (German for "beetle") and was later marketed as such in Germany, and as the Volkswagen in other countries. For example, in France it was known as the Coccinelle (French for ladybug).
The original 25 hp Beetle was designed for a top speed around 100 km/h, which would be a viable speed on the Reichsautobahn system. As Autobahn speeds increased in the postwar years, its output was boosted to 36, then 40 hp, the configuration that lasted through 1966 and became the "classic" Volkswagen motor. The Beetle ultimately gave rise to variants, including the Karmann Ghia, Type 2 and external coachbuilders. The Beetle marked a significant trend, led by Volkswagen, Fiat, and Renault, whereby the rear-engine, rear-wheel drive layout increased from 2.6 percent of continental Western Europe's car production in 1946 to 26.6 percent in 1956. The 1948 Citroën 2CV and other European models marked a later trend to front-wheel drive in the European small car market, a trend that would come to dominate that market. In 1974, Volkswagen's own front-wheel drive Golf model succeeded the Beetle. In 1994, Volkswagen unveiled the Concept One, a "retro"-themed concept car with a resemblance to the original Beetle, and in 1998 introduced the "New Beetle", built on the contemporary Golf platform with styling recalling the original Type 1. It remained in production through 2010, being succeeded in 2011 by the more aggressively styled Beetle (A5).
In the 1999 Car of the Century competition, to determine the world's most influential car in the 20th century, the Type 1 came fourth, after the Ford Model T, the Mini, and the Citroën DS.
HISTORY
THE PEOPLES CAR
In April 1934, Adolf Hitler gave the order to Ferdinand Porsche to develop a Volkswagen (literally, "people's car" in German, pronounced [ˈfɔlksvaːɡən]). The epithet Volks- literally, "people's-" had been applied to other Nazi-sponsored consumer goods such as the Volksempfänger ("people's radio").
In May 1934, at a meeting at Berlin’s Kaiserhof Hotel, Chancellor Hitler insisted on a basic vehicle that could transport two adults and three children at 100 km/h while not using more than 7 litres of fuel per 100 km (32 mpg US/39 mpg UK). The engine had to be powerful for sustained cruising on Germany’s new Autobahnen. Everything had to be designed to ensure parts could be quickly and inexpensively exchanged. The engine had to be air-cooled because, as Hitler explained, not every country doctor had his own garage (ethylene glycol antifreeze was only just beginning to be used in high-performance liquid-cooled aircraft engines. In general, radiators filled with water would freeze unless the vehicle was kept in a heated building overnight or drained and refilled each morning).
The "People's Car" would be available to citizens of Nazi Germany through a savings scheme, or Sparkarte (savings booklet), at 990 Reichsmark, about the price of a small motorcycle. (The average weekly income was then around 32RM.)
DEVELOPMENT
Ferdinand Porsche developed the Type 12, or "Auto für Jedermann" (car for everybody) for Zündapp in 1931. Porsche already preferred the flat-four engine, and selected a swing axle rear suspension (invented by Edmund Rumpler), while Zündapp insisted on a water-cooled five-cylinder radial engine. In 1932, three prototypes were running.[20] All of those cars were lost during World War II, the last in a bombing raid in Stuttgart in 1945.
The Zündapp prototypes were followed by the Porsche Type 32, designed in 1933 for NSU Motorenwerke AG, another motorcycle company. The Type 32 was similar in design to the Type 12, but it had a flat-four engine. NSU's exit from car manufacturing resulted in the Type 32 being abandoned at the prototype stage.
Initially designated Type 60 by Porsche, the design team included Erwin Komenda and Karl Rabe. In October 1935, the first two Type 60 prototypes, known as the V1 and V2 (V for Versuchswagen, or "test car"), were ready. In 1936, testing began of three further V3 prototypes, built in Porsche's Stuttgart shop. A batch of thirty W30 development models, produced for Porsche by Daimler-Benz, underwent 2,900,000 km of further testing in 1937. All cars had the distinctive round shape and the air-cooled, rear-mounted engine. Included in this batch was a rollback soft top called the Cabrio Limousine. A further batch of 44 VW38 pre-production cars produced in 1938 introduced split rear windows; both the split window and the dash were retained on production Type 1s until 1953. The VW38 cars were followed by another batch of 50 VW39 cars, completed in July 1939.
The car was designed to be as simple as possible mechanically. The air-cooled 25 hp (19 kW) 995 cc motors' built-in oil cooler and flat-four engine configuration's superior performance was also effective for the German Afrika Korps in Africa's desert heat. The suspension design used compact torsion bars instead of coil or leaf springs. The Beetle is nearly airtight and will briefly float.
THE FACTORY
On 26 May 1938, Hitler laid the cornerstone for the Volkswagen factory in Fallersleben. He gave a speech, in which he named the car Kraft-durch-Freude-Wagen ("Strength Through Joy Car", usually abbreviated to KdF-Wagen). The name refers to Kraft durch Freude ('Strength Through Joy'), the official leisure organization of Nazi Germany. The model village of Stadt des KdF-Wagens was created near Fallersleben in Lower Saxony in 1938 for the benefit of the workers at the newly built factory.
The factory had only produced a handful of cars by the start of the war in 1939; the first volume-produced versions of the car's chassis were military vehicles, the Type 82 Kübelwagen (approximately 52,000 built) and the amphibious Type 166 Schwimmwagen (about 14,000 built).
The first Beetles were produced on a small scale in 1941.
WARTIME PRODUCTION
A handful of KdF-Wagen (Typ 60) were produced primarily for the Nazi elite from 1941 to 1944, but production figures were small because the factories were concentrating on production of the Kübelwagen (Typ 82), the beetle for the Wehrmacht (Typ 82 E), the Schwimmwagen (Typ 166), and a handful of other variants. The factory produced another wartime vehicle: the Kommandeurswagen (Typ 87); a Beetle body mounted on a 4WD Schwimmwagen chassis. The Kommandeurswagen had widened fenders to accommodate its Kronprinz all-terrain tires. 564 Kommandeurswagen were produced up to 1944, when all production was halted because of heavy damage to the factory by Allied air raids. Much of the essential equipment had already been moved to underground bunkers for protection, which let production resume quickly after hostilities ended. Due to gasoline shortages late in the war, a few "Holzbrenner" Beetles were built powered by pyrolysis gas producers located under the front hood.
POST-WAR PRODUCTION AND BOOM
In occupied Germany, the Allies followed the Morgenthau plan to remove all German war potential by complete or partial pastoralization. As part of this, in the Industrial plans for Germany, the rules for which industry Germany was to be allowed to retain were set out. German car production was set at a maximum of 10% of the 1936 car production numbers.
Mass production of civilian VW cars did not start until post-war occupation. The Volkswagen factory was handed over by the Americans to British control in 1945; it was to be dismantled and shipped to Britain. Thankfully for Volkswagen, no British car manufacturer was interested in the factory; an official report included the phrases "the vehicle does not meet the fundamental technical requirement of a motor-car ... it is quite unattractive to the average buyer ... To build the car commercially would be a completely uneconomic enterprise." The factory survived by producing cars for the British Army instead. Allied dismantling policy changed in late 1946 to mid-1947, although heavy industry continued to be dismantled until 1951. In March 1947, Herbert Hoover helped change policy by stating
There is the illusion that the New Germany left after the annexations can be reduced to a "pastoral state". It cannot be done unless we exterminate or move 25,000,000 people out of it.
The re-opening of the factory is largely accredited to British Army officer Major Ivan Hirst. Hirst was ordered to take control of the heavily bombed factory, which the Americans had captured. His first task was to remove an unexploded bomb that had fallen through the roof and lodged itself between some pieces of irreplaceable production equipment; if the bomb had exploded, the Beetle's fate would have been sealed. Knowing Germany needed jobs and the British Army needed vehicles. Hirst persuaded the British military to order 20,000 cars, and by March 1946 the factory was producing 1,000 cars a month (in Army khaki, under the name Volkswagen Type 1), which Hirst said "was the limit set by the availability of materials". During this period, the car reverted to its original name of Volkswagen and the town was renamed Wolfsburg. The first 1,785 Type 1s were made in 1945.
After World War II, it was officially designated the Volkswagen Type 1, but was more commonly known as the Beetle.Following the British Army-led restart of productio
n and Hirst's establishment of sales network and exports to Netherlands, former Opel manager (and formerly a detractor of the Volkswagen) Heinz Nordhoff was appointed director of the Volkswagen factory in 1949. Under Nordhoff, production increased dramatically over the following decade, with the one-millionth car coming off the assembly line by 1955. During this post-war period, the Beetle had superior performance in its category with a top speed of 115 km/h and 0–100 km/h in 27.5 seconds with fuel consumption of 6.7 l/100 km (36 mpg) for the standard 25 kW (34 hp) engine. This was far superior to the Citroën 2CV, which was aimed at a low speed/poor road rural peasant market, and Morris Minor, designed for a market with no motorways / freeways; it was even competitive with more advanced small city cars like the Austin Mini.
In Small Wonder, Walter Henry Nelson wrote:
"The engine fires up immediately without a choke. It has tolerable road-handling and is economical to maintain. Although a small car, the engine has great elasticity and gave the feeling of better output than its small nominal size."
There were other, less-numerous models, as well. The Hebmüller cabriolet (officially Type 14A), a sporty two-seater, was built between 1949 and 1953; it numbered 696. The Type 18A, a fixed-top cabriolet, was produced by Austro-Tatra as a police and fire unit; 203 were assembled between January 1950 and March 1953.
The chassis became a technological and parts donor to Volkswagen Type 2 (also known as Bulli) and external coachbuilders like Rometsch, Dannenhauer & Stauss, Wilhelm Karmann, Enzmann, Beutler, Ghia-Aigle, Hebmüller & Söhne, Drews, Wendler.
On 17 February 1972, when Beetle No. 15,007,034 was produced, Beetle production surpassed that of the previous record holder, the Ford Model T. By 1973, total production was over 16 million, and by 23 June 1992, over 21 million had been produced.
DECLINE
Though extremely successful in the 1960s, the Beetle was increasingly faced with stiff competition from more modern designs globally. The Japanese had refined rear-wheel-drive, water-cooled, front-engine small cars including the Datsun 510 and Toyota Corona, whose sales in the North American market grew rapidly at the expense of Volkswagen in the late 1960s. Honda introduced the N600, based on the space-efficient transverse-engine, front-wheel-drive layout of the original Austin Mini, to the North American market in late 1969, and upgraded the model to the Honda Civic in 1972. The Japanese "big three" would soon dominate compact auto sales in North America. In 1971 Ford introduced its Pinto, which had some market impact as a low cost alternative. As the 1960s came to a close, Volkswagen faced increasingly stiff competition from European cars as well. The Beetle was faced with competition from new designs like the Fiat 127 and Renault 5, and more robust designs based on the Austin Mini layout such as the Superminis. German competitors, Ford and Opel also enjoyed strong sales of modern smaller cars like the Ford Escort and Opel Kadett. Volkswagen's attempts to boost the power of their air-cooled motor to meet the demands of higher highway speeds in the late 1960s, then comply with new pollution control regulations, caused problems for reliability and fuel efficiency that impaired the reputation of the aging design. Safety issues with the Beetle came under increasing scrutiny, culminating in the 1972 release of a rather scathing report. During the early 1970s, sales of the Beetle in Europe and North America plummeted.
There were other models introduced to supplement the Beetle in the VW product line throughout the 1960s; the Type 3, Type 4, and the NSU-based and larger K70. None of these models, aimed at more upscale markets, achieved the level of success as the Beetle. The over-reliance on a single model, now in decline, meant that Volkswagen was in financial crisis by 1974. It needed German government funding to produce the Beetle's replacement.
Production lines at Wolfsburg switched to the new water-cooled, front-engined, front-wheel drive Golf designed by Giorgetto Giugiaro in 1974, sold in North America at the time as the "Rabbit". The Golf would eventually become Volkswagen's most successful model since the Beetle. The Golf would be periodically redesigned over its lifetime, entering its seventh generation in 2012, with only a few components carried over between generations, while the Beetle had only minor refinements of its original design.
The Golf did not kill Beetle production, nor did the smaller Polo which was launched a year later. Production of the Beetle continued in smaller numbers at other German factories until 19 January 1978, when mainstream production shifted to Brazil and Mexico: markets where low operating cost was an important factor. However, this shift in production did not completely end sales of the Beetle in Europe, although after this date sales of the Beetle in Europe were very low. Beetle sedans were produced for U.S. markets until July 1977 and for European markets until 1985, with private companies continuing to import cars produced in Mexico after 1985. The Beetle convertible/Cabriolet ended production (as 1979 models) as of January 31, 1980.
The last Beetle was produced in Puebla, Mexico, in July 2003. The final batch of 3,000 Beetles were sold as 2004 models and badged as the Última Edición, with whitewall tires, a host of previously discontinued chrome trim, and the choice of two special paint colors taken from the New Beetle. Production in Brazil ended in 1986, then started again in 1993 and continued until 1996.
The Beetle outlasted most other cars which had adopted the rear air-cooled engine layout such as those by Subaru, Fiat, and General Motors. Porsche's 356 series which originally used some Volkswagen sourced parts, continued to use the classic rear engine layout (which later became water-cooled) in the Porsche 911 996 series, which remains competitive in the second decade of the 21st century.
WORLDWIDE END OF PRODUCTION
By 2002, over 21 million Type 1s had been produced, but by 2003, annual production had dropped to 30,000 from a peak of 1.3 million in 1971. VW announced the end of production in June 2003, citing decreasing demand, and the final original Type 1 VW Beetle (No. 21,529,464) rolled off the production line at Puebla, Mexico, on 30 July 2003 65 years after its original launch. This last Beetle, nicknamed El Rey (Spanish for "The King" after a legendary Mexican song by José Alfredo Jiménez) was delivered to the company's museum in Wolfsburg, Germany.
To celebrate the occasion, Volkswagen marketed a final special series of 3,000 Beetles marketed as "Última Edición" (Final Edition) in light blue (Aquarius Blue) or beige (Harvest Moon Beige). Each car included the 1.6 engine, whitewall tires, a CD player with four speakers, chrome bumpers, trim, hub caps and exterior mirrors, a Wolfsburg emblem above the front trunk's handle, chrome glove box badge, body coloured wheels, tinted glass, a rear parcel shelf, and VW Última Edición plaque.
A mariachi band serenaded production of the last car. In Mexico, there was an advertising campaign as a goodbye for the Beetle. In one of the ads was a very small parking space on the street, and many big cars tried to use it, but could not. After a while, a sign appears in that parking space saying: "Es increíble que un auto tan pequeño deje un vacío tan grande" (It is incredible that a car so small can leave such a large void). Another depicted the rear end of a 1954 Beetle (the year Volkswagen was established in Mexico) in the left side of the ad, reading "Erase una vez..." (Once upon a time...) and the last 2003 Beetle in the right side, reading "Fin" (The end). There were other ads with the same nostalgic tone.

PROTOTYPES
DIESEL
In 1951, Volkswagen prototyped a 1.3 L diesel engine. Volkswagen made only two of these air-cooled boxer diesel engines (not turbocharged), and installed one engine in a Type 1 and another in a Type 2. The diesel Beetle was time tested on the Nürburgring and achieved 0–100 km/h in 60 seconds.
DESIGN
The Beetle featured a rear-located, rear-wheel drive, air-cooled four-cylinder, boxer engine in a two-door bodywork featuring a flat front windscreen, accommodating four passengers and providing luggage storage under the front bonnet and behind the rear seat – and offering a coefficient of drag of 0.41; to this relatively good CD, the also streamlined rear of car was of help. The bodywork attached with eighteen bolts to its nearly flat chassis which featured a central structural tunnel. Front and rear suspension featured torsion bars along with front stabilizer bar – providing independent suspension at all wheels. Certain initial features were subsequently revised, including mechanical drum brakes, split-window rear windows, mechanical direction-indicators and the non-synchronized gearbox. Other features, including its distinctive overall shape, endured.
Its engine, transmission, and cylinder heads were constructed of light alloy. An engine oil cooler (located in the engine fan's shroud) ensured optimal engine operating temperature and long engine life, optimized by a thermostat that bypassed the oil cooler when the engine was cold. Later models of the carburetor featured an automatic choke. Engine intake air passed through a metallic filter, while heavier particles were captured by an oil bath. After 1960, steering featured a hydraulic damper that absorbed steering irregularities.
Indicative of the car's utilitarian design, the interior featured painted metal surfaces, a metal dash consolidating instruments in a single, circular binnacle, adjustable front seats, a fold-down rear seat, optional swing-out rear windows, front windows with pivoting vent windows, heating via air-to-air exchange manifolds operating off the engine's heat, and a windshield washer system that eschewed the complexity and cost of an additional electric pump and instead received its pressurization from the car's spare tire (located in the front luggage compartment) which was accordingly overinflated to accommodate the washer function.
Throughout its production, VW marketed the Beetle with a four-speed manual transmission. From 1961 (and almost exclusively in Europe), VW offered an optional version of the Saxomat semi-automatic transmission: a regular 4-speed manual transaxle coupled to an electromagnetic clutch with a centrifugal clutch used for idle. Subsequently (beginning in 1967 in Europe and 1968 in the United States), VW offered an optional semi-automatic transmission (marketed as Automatic Stick Shift and also called AutoStick[citation needed]), which was a 3-speed manual coupled to an electro-pneumatic clutch and torque converter.
While the overall appearance of the Beetle changed little over its life span, it received over 78,000 incremental changes during its production.
EVOLUTION AND DESIGN CHANGES
BEETLE CABRIOLET
It was in 1948 that Wilhelm Karmann first bought a VW Beetle sedan and converted it into a four-seated convertible. The Beetle Cabriolet began production in 1949 by Karmann in Osnabrück. After successfully presenting it at VW in Wolfsburg, production started in 1949.
The convertible was more than a Beetle with a folding top. To compensate for the strength lost in removing the roof, the sills were reinforced with welded U-channel rails, a transverse beam was fitted below the front edge of the rear seat cushion, and the side cowl-panels below the instrument panel were double-wall. In addition, the lower corners of the door apertures had welded-in curved gussets, and the doors had secondary alignment wedges at the B-pillar.
The top was cabriolet-style with a full inner headliner hiding the folding mechanism and crossbars. In between the two top layers was 25 mm of insulation. The rear window was tempered safety glass, and after 1968, heated. Due to the thickness of the top, it remained quite tall when folded. To enable the driver to see over the lowered top, the inside rearview was mounted on an offset pivot. By twisting the mirror 180 degrees on a longitudinal axis, the mirror glass would raise approximately 5.1 cm.
The convertible was generally more lavishly equipped than the sedan with dual rear ashtrays, twin map pockets, a visor vanity mirror on the passenger side, rear stone shields, and through 1969, wheel trim rings. Many of these items did not become available on other Beetles until the advent of the optional "L" (Luxus) Package of 1970.
After a number of stylistic and technical alterations made to the Karmann cabriolet, (corresponding to the many changes VW made to the Beetle throughout its history), the last of 331,847 cabriolets came off the production line on 10 January 1980.
1950–1959 MODELS
During this period, a myriad of changes were made throughout the vehicle beginning with the availability of hydraulic brakes and a folding fabric sunroof in 1950. The rear window of the VW Beetle evolved from a divided or "split" oval, to a singular oval. The change occurred between October 1952 and March 1953. Beetles built during this time were known as a "Zwitter", or "hybrid", as they used the split-window bodyshell with oval-model chrome trim, vent windows and dashboard.
1953 models received a redesigned instrument panel. The one-piece “Pope's Nose” combination license plate/brake light was replaced by a smaller flat-bottomed license plate light. The brake light function was transferred to new heart-shaped lamps located in the top of the taillight housings.
In 1954, Volkswagen added 2 mm to the cylinder bore, increasing the displacement from 1,131 (1100) cc to 1,192 (1200) cc. This coincided with upgrades to various key components including a redesign of the crankshaft. This increased power from 30 hp (22 kW; 30 PS) to 36 hp (27 kW; 36 PS) and improved the engine's free revving abilities without compromising torque at lower engine speeds. At the same time, compression ratios were progressively raised as, little by little, the octane ratings of available fuel was raised in major markets during the 1950s and 1960s.
In 1955, the separate brake lights were discontinued and were combined into a new larger taillight housing. The traditional VW semaphore turn signals were replaced by conventional flashing directional indicator lamps for North America.
For 1956, the Beetle received what would become one of its more distinctive features, a set of twin chrome tailpipes. Models for North America gained taller bumper guards and tubular overrider bars.
For 1958, the Beetle received a revised instrument panel, and a larger rectangular rear window replaced the previous oval design.
1960–1969 MODELS
1960 models received a front sway bar along with a hydraulic steering damper.
For 1961, significant technical advances occurred in the form of a new engine and transmission. The engine remained at 1200cc but the power increased to 40 hp (30 kW; 41 PS) primarily due to an increase in compression ratio to 7.1:1. The carburetor received an electric automatic choke and the transmission was now synchronized on all forward gears. The traditional semaphore turns signals were replaced by conventional flashing directional indicators worldwide.
For 1962, the Beetle received a mechanical fuel level gauge in place of the former fuel tap. At the rear, larger tail lights were introduced incorporating a separate amber turn signal section to meet new European standards (these turn signals remained red in the US market until 1973). The former hand-pump style windscreen washer was replaced by a new design using compressed air. A Schrader valve located on the washer fluid tank allowed the system to be charged at a filling station to the recommended 35 psi (2.4 bar).
1964 models could be identified by a widened light housing on the engine lid over the rear license plate.
The largest change to date for the Beetle was in 1965: the majority of the body stampings were revised, which allowed for significantly larger windows. The windshield increased in area by 11% and was now slightly curved, rather than flat. Door windows increased accordingly by 6% (and door vent window edges were canted slightly back), rear side windows 17.5%, and the rear window 19.5%. The result was a more open, airy, modern look.
For 1966, the big news was an optional new 1300cc 50 hp (37 kW; 51 PS) engine in lieu of the previous 1200cc engine that had been the sole engine since 1954. Models so equipped carried a "1300" badge on the engine lid. The 1300cc engine was standard for North America.
For 1967, a yet-again larger-displacement engine was made available: 1500cc, 53 hp (40 kW; 54 PS) at 4,200 rpm. 1200 and 1300 engines continued to be available, as many markets based their taxation on engine size. 1500cc Beetles were equipped with front disc brakes and were identified with a "VW 1500" badge on the engine lid. North America received the 1500 engine as standard equipment, but did not receive front disc brakes. These models were identified by a "Volkswagen" badge on the engine lid.
The rear suspension was significantly revised including a widened track, softer torsion bars and the addition of a unique Z-configuration equalizing torsion spring. On US, UK and Ireland models, the generator output was increased from 180 to 360 watts, and the entire electrical system was upgraded from 6 volts to 12 volts. The clutch disc also increased in size and changes were made to the flywheel. New equipment included a driver's armrest on the door and locking buttons on both doors. Safety improvements included two-speed windscreen wipers, reversing lights (in some markets), and a driver's side mirror. In accord with the newly enacted US Federal Motor Vehicle Safety Standard 108, North American models received a dual-circuit brake system, the clear glass headlamp covers were deleted; the headlamps were brought forward to the leading edge of the front fenders, and the sealed-beam units were exposed and surrounded by chrome bezels.
1968 was a year of major change. The most noticeable of which were the new larger, higher mounted C-section bumpers. At the rear, new larger taillamps were adopted and were able to accommodate backup lamps, which were previously separate bumper-mounted units. Beetles worldwide received the '67 North American style vertical headlamp placement, but with replaceable-bulb headlamps compliant with ECE regulations rather than the US sealed beams. Other improvements were a new outside gas filler with spring-loaded flap, eliminating the need to open the trunk to refuel. The fuel gauge was integrated with the speedometer and was now electrically-actuated rather than cable-operated. The windscreen washer was now pressured by the spare tire, which was to be maintained at a pressure of 42 psi (2.9 bar). A pressure valve in the connecting hose closed airflow to the fluid reservoir if spare tire pressure fell below 30 psi (2.1 bar), which was above the recommended pressures for the road tires. A ventilation system was introduced, which drew fresh air into the cabin from louvres on the front decklid. For improved shifting, the shift lever was shortened, stiffened and moved rearward by
78 mm.
A number of safety improvements were made in order to comply with new American safety regulations: these included trigger-operated outside door handles, a secondary front hood latch, collapsing steering column, soft vent window latches, rotary glove compartment latch and instrument panel knobs labeled with pictographs. US models received a padded instrument panel that was optional in other markets. To meet North American head restraint requirements, VW developed the industry's first high-back bucket seat.
A new 3-speed semi-automatic gear box with torque converter and vacuum-operated clutch became available mid-production year. The semi-automatic models received a vastly improved semi-trailing-arm rear suspension (also known as "Independent Rear Suspension" although the earlier swing axle Beetles were also independent) and eliminated the need for the equalizing torsion spring. This new rear suspension layout would eventually become an option on later models. Beetles equipped with the automatic were identified with a "VW Automatic" badge on the engine lid and a matching decal in the rear window. In North America, the badging and decal were later revised to read, "Automatic Stick Shift".
For 1969, the only exterior change was the fuel filler flap no longer had a finger indentation due to a new interior-mounted fuel door release. For North America, the Beetle received a heated rear window, day/night mirror and the semi-trailing, independent rear-arm suspension as standard equipment.
1970–1979 MODELS
In 1970, A new "L" (Luxus) Package was introduced including, among other items, twin map pockets, dual rear ashtrays, full carpeting, a passenger-side visor vanity mirror, and rubber bumper moldings. The optional 1500 cc engine now came with an engine lid having two rows of cooling louvers, while the convertible's engine lid gained two additional sets for a total of four. For North America, the 1500 cc engine was enlarged to 1600 cc engine and produced 57 hp (43 kW; 58 PS)
For 1971, for the first time there were two Beetles, the familiar standard Beetle and a new larger version that was different from the windscreen forward. All Beetles received an engine upgrade: the optional 1500 cc engine was replaced by a 1600 cc version with twin-port cylinder heads and a larger, relocated oil cooler. The new engine produced 60 hp (45 kW; 61 PS). The ventilation system was improved with the original dash-top vents augmented by a second pair aimed directly at the driver and passenger. For the first time the system was a flow-through design with crescent-shaped air exits fitted behind the rear quarter windows. Airflow could be increased via an optional 2-speed fan. The standard Beetle was now badged as the VW 1300; when equipped with the 1600 engine, it was badged 1300 S, to avoided confusion with the Type 3, which wore VW 1600 badges.
The new larger Beetle was sold as the 1302/1302 S, offering nearly 50% increased luggage capacity. A new MacPherson strut front suspension was incorporated, similar to what was used in the Type 4, and the front track was widened. The new suspension layout allowed the spare tire to be positioned flat under the trunk floor, although the car had to be lengthened slightly to accomplish this. This also allowed a reduction in turning radius. To gain additional trunk volume, the under-dash panel was lowered, allowing the fuel tank to be shifted rearward. From the windscreen back the big Beetle was identical to its smaller progenitor, except for having the semi-trailing arm rear suspension as standard equipment. Overall, the big Beetle was 50 mm longer in length and 35 mm wider and rode on a 20 mm longer wheelbase than the standard model. Both Beetles were available with or without the L Package. The convertible was now based on the 1302 body. In North America, the 1302 was marketed as the Super Beetle and came only with the L Package and 1600 cc engine. While it lacked the front disc brakes that normally accompanied the larger motor, it was fitted with brake drums that were slightly larger than the standard Beetle. With the Super Beetle being sold as the premium model in North America, the standard Beetle, while retaining the same 1600 cc engine, was stripped of many of its earlier features in order to reduce the selling price. Bright window and running board moldings disappeared, along with the day/night mirror, horn ring, map pocket, locking glove box and miscellaneous other items.
1972 models had an 11% larger rear window 40 mm taller, larger front brakes[citation needed] and the convertible engine lid with four rows of louvres was now used on all Beetles. Inside the vehicle, a four-spoke energy-absorbing steering wheel was introduced, the windshield wiper/washer knob was replaced in favor of a steering column stalk, and intermittent wipers were a new option available in selected markets. An engine compartment socket for the proprietary VW Diagnosis system was also introduced. The rear luggage area was fitted with a folding parcel shelf. A limited-edition Commemorative model was launched in celebration of the Beetle's passing the record of the Ford Model T as the world's most-produced automobile. The Commemorative Beetle was a 1302 LS finished in a special Marathon Blue Metallic paint and unique 4.5 x 15 styled steel wheels. In the U.S., it was marketed as the Super Beetle Baja Champion SE.
1973 models featured significantly-enlarged "elephant foot" taillamps mounted in reshaped rear fenders. In the engine bay, the oil-bath air cleaner gave way to a dry element filter, and the generator was replaced with an alternator. The 1302/Super became the 1303 with a new taller wrap-around windscreen. The changes to the cowl and windshield resulted in slight redesign of the front hood. The instrument panel, formerly shared with the standard Beetle, was all-new and incorporated a raised speedometer pod, rocker-style switches and side-window defrosters. The limited-edition GSR (Gelb-Schwarz Rennen) was a 1303 S available only in Saturn Yellow paint equipped with special 140 mm wide sport wheels fitted with 175/70-15 Pirelli Cinturato CN36 high-performance radial tires. Front and rear deck lids were finished in matte black, as was all exterior trim with the exception of the chrome headlamp bezels. Inside were corduroy and leatherette high-bolstered sport seats and a small diameter three-spoke steering wheel with padded leather rim and a small red VW logo on the bottom spoke. In North America, the GSR was sold as the Super Beetle Sports Bug. The North American model had body-color deck lids and was available in Marathon Blue Metallic in addition to Saturn Yellow. In some markets, the sport wheels (in both 4.5-inch and 5.5-inch widths), sport steering wheel and sport seats became available as stand-alone options.
For 1974, North American models received newly required 8.0 km/h impact bumpers mounted on self-restoring energy absorbers, which added approximately 25 mm to the car's overall length. On the Super Beetle, the steering knuckle, and consequently the lower attachment point of the strut, was redesigned to improve handling and stability in the event of a tire blowout. A limited-edition Big Beetle was introduced based on the 1303 LS. Available in unique metallic paint colors, the car featured styled-steel 5.5 in (140 mm) wide sport wheels wrapped in 175/70-15 tires, corduroy seat inserts, upgraded loop-pile carpet, wood-look instrument panel trim and a padded steering wheel with bright accents. In the North American market, a limited-edition Sun Bug was introduced as a standard Beetle or Super Beetle. Both were finished in metallic gold and featured styled-steel 4.5 in (110 mm)-wide sport wheels. Inside were brown corduroy and leatherette seats, loop-pile carpet, and padded four-spoke deluxe steering wheel. The Super Beetle Sun Bug included a sliding-steel sunroof.
In 1975, front turn indicators were moved from the top of the front fenders down into the bumper. At the rear, the license plate light housing was now molded of plastic with a ribbed top surface. To comply with tightening emission standards, the 1600 cc engine in Japanese and North American markets received Bosch L-Jetronic fuel injection, a derivative of the Bosch D-Jetronic system formerly used in the VW Type 3 and Type 4. The injected engine received a new muffler and in California a catalytic converter. This necessitated a bulge in the rear apron under the rear bumper and replaced the distinctive twin "pea shooter" tailpipes with a single offset pipe, making injected models identifiable at a glance. 5 mph (8.0 km/h) bumper-equipped North American models retained fender-top front indicators. The 1303 received rack and pinion steering. In North America, the 1303/Super Beetle sedan was moved upmarket and was now christened La Grande Bug. Similar to the Big Beetle of 1974, La Grande Bug was available in blue or green metallic paint in the U.S. and blue, green or gold metallic in Canada and was equipped with the same features as the 1974 Sun Bug. Mid-year, the Love Bug was introduced for North America: based on the standard Beetle, it was available only in Phoenix Red or Ravenna Green (both colors shared with the VW-Porsche 914) with all exterior trim finished in matte black. A price leader, the Love Bug retailed for less than a standard Beetle. The "Volkswagen" script on the engine lid of all North American Beetles was replaced with a "Fuel Injection" badge.
In 1976, the 1303/La Grande Bug was discontinued, with the larger body continuing only in convertible form. To make up for the loss in North American markets, the standard Beetle was upgraded, regaining some of the features that were removed in 1971. In addition, the 2-speed ventilation fan was included, previously available in North America only on the larger Beetle. The automatic stickshift option was discontinued as well.
1977 models received new front seats with separate head restraints. This was the final model year for the Beetle sedan in North America. The convertible was offered in a Champagne Edition in triple white with the padded deluxe steering wheel, burled elm-grain dash trim and (110 mm wide sport wheels. Approximately 1,000 Champagne Editions were produced.

Pasted from Wikipedia: Bell-Boeing V-22 Osprey
• • • • •
The Bell-Boeing V-22 Osprey is a multi-mission, military, tiltrotor aircraft with both a vertical takeoff and landing (VTOL), and short takeoff and landing (STOL) capability. It is designed to combine the functionality of a conventional helicopter with the long-range, high-speed cruise performance of a turboprop aircraft.
The V-22 originated from the U.S. Department of Defense Joint-service Vertical take-off/landing Experimental (JVX) aircraft program started in 1981. It was developed jointly by the Bell Helicopter, and Boeing Helicopters team, known as Bell Boeing, which produce the aircraft.[4] The V-22 first flew in 1989, and began years of flight testing and design alterations.
The United States Marine Corps began crew training for the Osprey in 2000, and fielded it in 2007. The Osprey's other operator, the U.S. Air Force fielded their version of the tiltrotor in 2009. Since entering service with the U.S. Marine Corps and Air Force, the Osprey has been deployed for combat operations in Iraq and Afghanistan.

Development
Early development
The failure of the Iran hostage rescue mission in 1980 demonstrated to the United States military a need[5] for "a new type of aircraft, that could not only take off and land vertically but also could carry combat troops, and do so at speed."[6] The U.S. Department of Defense began the Joint-service Vertical take-off/landing Experimental (JVX) aircraft program in 1981, under U.S. Army leadership. Later the U.S. Navy/Marine Corps took the lead.[7][8] The JVX combined requirements from the Marine Corps, Air Force, Army and Navy.[9][10] A request for proposals (RFP) was issued in December 1982 for JVX preliminary design work. Interest in the program was expressed by Aérospatiale, Bell Helicopter, Boeing Vertol, Grumman, Lockheed, and Westland. The DoD pushed for contractors to form teams. Bell partnered with Boeing Vertol. The Bell Boeing team submitted a proposal for a enlarged version of the Bell XV-15 prototype on 17 February 1983. This was the only proposal received and a preliminary design contract was awarded on 26 April 1983.[11][12]
The JVX aircraft was designated V-22 Osprey on 15 January 1985; by March that same year the first six prototypes were being produced, and Boeing Vertol was expanded to deal with the project workload.[13][14] Work has been split evenly between Bell and Boeing. Bell Helicopter manufactures and integrates the wing, nacelles, rotors, drive system, tail surfaces, and aft ramp, as well as integrates the Rolls-Royce engines and performs final assembly. Boeing Helicopters manufactures and integrates the fuselage, cockpit, avionics, and flight controls.[4][15] The USMC variant of the Osprey received the MV-22 designation and the Air Force variant received CV-22; reversed from normal procedure to prevent Marine Ospreys from having a conflicting designation with aircraft carriers (CV).[16] Full-scale development of the V-22 tilt-rotor aircraft began in 1986.[2] On 3 May 1986 the Bell-Boeing partnership was awarded a $1.714 billion contract for V-22 aircraft by the Navy, thus at this point the project had acquisition plans with all four arms of the U.S. military.[17]
The first V-22 was rolled out with significant media attention in May 1988.[18][19] However the project suffered several political blows. Firstly in the same year, the Army left the program, citing a need to focus its budget on more immediate aviation programs.[20] The project also faced considerable dialogue in the Senate, surviving two votes that both could have resulted in cancellation.[21][22] Despite the Senate's decision, the Department of Defense instructed the Navy not to spend more money on the Osprey.[23] At the same time, the Bush administration sought the cancellation of the project.[23]
Flight testing and design changes
The first of six MV-22 prototypes first flew on 19 March 1989 in the helicopter mode,[24] and on 14 September 1989 as a fixed-wing plane.[25] The third and fourth prototypes successfully completed the Osprey's first Sea Trials on the USS Wasp in December 1990.[26] However, the fourth and fifth prototypes crashed in 1991-92.[27] Flight tests were resumed in August 1993 after changes were incorporated in the prototypes.[2] From October 1992 until April 1993, Bell and Boeing redesigned the V-22 to reduce empty weight, simplify manufacture and reduce production costs. This redesigned version became the B-model.[28]
Flight testing of four full-scale development V-22s began in early 1997 when the first pre-production V-22 was delivered to the Naval Air Warfare Test Center, Naval Air Station Patuxent River, Maryland. The first EMD flight took place on 5 February 1997. The first of four low rate initial production aircraft, ordered on 28 April 1997, was delivered on 27 May 1999. Osprey number 10 completed the program's second Sea Trials, this time from the USS Saipan in January 1999.[2] During external load testing in April 1999, Boeing used a V-22 to lift and transport the M777 howitzer.[29] In 2000, Boeing announced that the V-22 would be fitted with a nose-mounted GAU-19 Gatling gun,[30] but the GAU-19 gun was later canceled.[31]
In 2000, there were two further fatal crashes, killing a total of 19 Marines, and the production was again halted while the cause of these crashes was investigated and various parts were redesigned.[32] The V-22 completed its final operational evaluation in June 2005. The evaluation was deemed successful; events included long range deployments, high altitude, desert and shipboard operations. The problems identified in various accidents had been addressed.[33]
Controversy
The V-22's development process has been long and controversial, partly due to its large cost increases.[34] When the development budget, first planned for $2.5 billion in 1986, increased to a projected $30 billion in 1988, then-Defense Secretary Dick Cheney tried to zero out its funding. He was eventually overruled by Congress.[32] As of 2008, $27 billion have been spent on the Osprey program and another $27.2 billion will be required to complete planned production numbers by the end of the program.[2]
The V-22 squadron's former commander at Marine Corps Air Station New River, Lt. Colonel Odin Lieberman, was relieved of duty in 2001 after allegations that he instructed his unit that they needed to falsify maintenance records to make the plane appear more reliable.[2][35] Three officers were later implicated in the falsification scandal.[34]
The aircraft is incapable of autorotation, and is therefore unable to land safely in helicopter mode if both engines fail. A director of the Pentagon's testing office in 2005 said that if the Osprey loses power while flying like a helicopter below 1,600 feet (490 m), emergency landings "are not likely to be survivable". But Captain Justin (Moon) McKinney, a V-22 pilot, says that this will not be a problem, "We can turn it into a plane and glide it down, just like a C-130".[31] A complete loss of power would require the failure of both engines, as a drive shaft connects the nacelles through the wing; one engine can power both proprotors.[36] While vortex ring state (VRS) contributed to a deadly V-22 accident, the aircraft is less susceptible to the condition than conventional helicopters and recovers more quickly.[5] The Marines now train new pilots in the recognition of and recovery from VRS and have instituted operational envelope limits and instrumentation to help pilots avoid VRS conditions.[32][37]
It was planned in 2000 to equip all V-22s with a nose-mounted Gatling gun, to provide "the V-22 with a strong defensive firepower capability to greatly increase the aircraft's survivability in hostile actions."[30] The nose gun project was canceled however, leading to criticism by retired Marine Corps Commandant General James L. Jones, who is not satisfied with the current V-22 armament.[31] A belly-mounted turret was later installed on some of the first V-22s sent to the War in Afghanistan in 2009.[38]
With the first combat deployment of the MV-22 in October 2007, Time Magazine ran an article condemning the aircraft as unsafe, overpriced, and completely inadequate.[31] The Marine Corps, however, responded with the assertion that much of the article's data were dated, obsolete, inaccurate, and reflected expectations that ran too high for any new field of aircraft.[39]
Recent development
On 28 September 2005, the Pentagon formally approved full-rate production for the V-22.[40] The plan is to boost production from 11 a year to between 24 and 48 a year by 2012. Of the 458 total planned, 360 are for the Marine Corps, 48 for the Navy, and 50 for the Air Force at an average cost of $110 million per aircraft, including development costs.[2] The V-22 had an incremental flyaway cost of $70 million per aircraft in 2007,[3] but the Navy hopes to shave about $10 million off that cost after a five-year production contract starts in 2008.[41]
The Bell-Boeing Joint Project Office in Amarillo, Texas will design a new integrated avionics processor to resolve electronics obsolescence issues and add new network capabilities.[42]
Design
The Osprey is the world's first production tiltrotor aircraft, with one three-bladed proprotor, turboprop engine, and transmission nacelle mounted on each wingtip. It is classified as a powered lift aircraft by the Federal Aviation Administration.[43] For takeoff and landing, it typically operates as a helicopter with the nacelles vertical (rotors horizontal). Once airborne, the nacelles rotate forward 90° in as little as 12 seconds for horizontal flight, converting the V-22 to a more fuel-efficient, higher-speed turboprop airplane. STOL rolling-takeoff and landing capability is achieved by having the nacelles tilted forward up to 45°. For compact storage and transport, the V-22's wing rotates to align, front-to-back, with the fuselage. The proprotors can also fold in a sequence taking 90 seconds.[44]
Most Osprey missions will use fixed wing flight 75 percent or more of the time, reducing wear and tear on the aircraft and reducing operational costs.[45] This fixed wing flight is higher than typical helicopter missions allowing longer range line-of-sight communications and so improved command and control.[2] Boeing has stated the V-22 design loses 10% of its vertical lift over a Tiltwing design when operating in helicopter mode because of airflow resistance due to the wings, but that the Tiltrotor design has better short takeoff and landing performance.[46]
The V-22 is equipped with a glass cockpit, which incorporates four Multi-function displays (MFDs) and one shared Central Display Unit (CDU), allowing the pilots to display a variety of images including: digimaps centered or decentered on current position, FLIR imagery, primary flight instruments, navigation (TACAN, VOR, ILS, GPS, INS), and system status. The flight director panel of the Cockpit Management System (CMS) allows for fully-coupled (aka: autopilot) functions which will take the aircraft from forward flight into a 50-foot hover with no pilot interaction other than programming the system.[47] The glass cockpit of the canceled CH-46X was derived from the V-22.[48]
The V-22 is a fly-by-wire aircraft with triple-redundant flight control systems.[49] With the nacelles pointing straight up in conversion mode at 90° the flight computers command the aircraft to fly like a helicopter, with cyclic forces being applied to a conventional swashplate at the rotor hub. With the nacelles in airplane mode (0°) the flaperons, rudder, and elevator fly the aircraft like an airplane. This is a gradual transition and occurs over the rotation range of the nacelles. The lower the nacelles, the greater effect of the airplane-mode control surfaces.[50] The nacelles can rotate past vertical to 97.5° for rearward flight.[51][52]
The Osprey can be armed with one M240 7.62x51mm NATO (.308 in caliber) or M2 .50 in caliber (12.7 mm) machine gun on the loading ramp, that can be fired rearward when the ramp is lowered. A GAU-19 three-barrel .50 in gatling gun mounted below the V-22's nose has also been studied for future upgrade.[31][53] BAE Systems developed a remotely operated turreted weapons system for the V-22,[54] which was installed on half of the first V-22s deployed to Afghanistan in 2009.[38] The 7.62 mm belly gun turret is remotely operated by a gunner inside the aircraft, who acquires targets with a separate pod using color television and forward looking infrared imagery.
U.S. Naval Air Systems Command is working on upgrades to increase the maximum speed from 250 knots (460 km/h; 290 mph) to 270 knots (500 km/h; 310 mph), increase helicopter mode altitude limit from 10,000 feet (3,000 m) to 12,000 feet (3,700 m) or 14,000 feet (4,300 m), and increase lift performance.[55]
Operational history
US Marine Corps
Marine Corps crew training on the Osprey has been conducted by VMMT-204 since March 2000. On 3 June 2005, the Marine Corps helicopter squadron Marine Medium Helicopter 263 (HMM-263), stood down to begin the process of transitioning to the MV-22 Osprey.[56] On 8 December 2005, Lieutenant General Amos, commander of the II MEF, accepted the delivery of the first fleet of MV-22s, delivered to HMM-263. The unit reactivated on 3 March 2006 as the first MV-22 squadron and was redesignated VMM-263. On 31 August 2006, VMM-162 (the former HMM-162) followed suit. On 23 March 2007, HMM-266 became Marine Medium Tiltrotor Squadron 266 (VMM-266) at Marine Corps Air Station New River, North Carolina.[57]
The Osprey has been replacing existing CH-46 Sea Knight squadrons.[58] The MV-22 reached initial operational capability (IOC) with the U.S. Marine Corps on 13 June 2007.[1] On 10 July 2007 an MV-22 Osprey landed aboard the Royal Navy aircraft carrier, HMS Illustrious in the Atlantic Ocean. This marked the first time a V-22 had landed on any non-U.S. vessel.[59]
On 13 April 2007, the U.S. Marine Corps announced that it would be sending ten V-22 aircraft to Iraq, the Osprey's first combat deployment. Marine Corps Commandant, General James Conway, indicated that over 150 Marines would accompany the Osprey set for September deployment to Al-Asad Airfield.[60][61] On 17 September 2007, ten MV-22Bs of VMM-263 left for Iraq aboard the USS Wasp. The decision to use a ship rather than use the Osprey's self-deployment capability was made because of concerns over icing during the North Atlantic portion of the trip, lack of available KC-130s for mid-air refueling, and the availability of the USS Wasp.[62]
The Osprey has provided support in Iraq, racking up some 2,000 flight hours over three months with a mission capable availability rate of 68.1% as of late-January 2008.[63] They are primarily used in Iraq's western Anbar province for routine cargo and troop movements, and also for riskier "aero-scout" missions. General David Petraeus, the top U.S. military commander in Iraq, used one to fly around Iraq on Christmas Day 2007 to visit troops.[64] Then-presidential candidate Barack Obama also flew in Ospreys during his high profile 2008 tour of Iraq.[65]
The only major problem has been obtaining the necessary spare parts to maintain the aircraft.[66] The V-22 had flown 3,000 sorties totaling 5,200 hours in Iraq as of July 2008.[67] USMC leadership expect to deploy MV-22s to Afghanistan in 2009.[66][68] General George J. Trautman, III praised the increased range of the V-22 over the legacy helicopters in Iraq and said that "it turned his battle space from the size of Texas into the size of Rhode Island."[69]
Naval Air Systems Command has devised a temporary fix for sailors to place portable heat shields under Osprey engines to prevent damage to the decks of some of the Navy's smaller amphibious ships, but they determined that a long term solution to the problem would require these decks be redesigned with heat resistant deck coatings, passive thermal barriers and changes in ship structure in order to operate V-22s and F-35Bs.[70]
A Government Accountability Office study reported that by January 2009 the Marines had 12 MV-22s operating in Iraq and they managed to successfully complete all assigned missions. The same report found that the V-22 deployments had mission capable rates averaging 57% to 68% and an overall full mission capable rate of only 6%. It also stated that the aircraft had shown weakness in situational awareness, maintenance, shipboard operations and the ability to transport troops and external cargo.[71] That study also concluded that the "deployments confirmed that the V-22’s enhanced speed and range enable personnel and internal cargo to be transported faster and farther than is possible with the legacy helicopters it is replacing".[71]
The MV-22 saw its first offensive combat mission, Operation Cobra's Anger on 4 December 2009. Ospreys assisted in inserting 1,000 Marines and 150 Afghan troops into the Now Zad Valley of Helmand Province in southern Afghanistan to disrupt communication and supply lines of the Taliban.[38] In January 2010 the MV-22 Osprey is being sent to Haiti as part of Operation Unified Response relief efforts after the earthquake there. This will be the first use the Marine V-22 in a humanitarian mission.[72]
US Air Force
The Air Force's first operational CV-22 Osprey was delivered to the 58th Special Operations Wing (58th SOW) at Kirtland Air Force Base, New Mexico on 20 March 2006. This and subsequent aircraft will become part of the 58th SOW's fleet of aircraft used for training pilots and crew members for special operations use.[73] On 16 November 2006, the Air Force officially accepted the CV-22 in a ceremony conducted at Hurlburt Field, Florida.[74]
The US Air Force's first operational deployment of the Osprey sent four CV-22s to Mali in November 2008 in support of Exercise Flintlock. The CV-22s flew nonstop from Hurlburt Field, Florida with in-flight refueling.[5] AFSOC declared that the 8th Special Operations Squadron reached Initial Operational Capability on 16 March 2009, with six of its planned nine CV-22s operational.[75]
In June 2009, CV-22s of the 8th Special Operations Squadron delivered 43,000 pounds (20,000 kg) of humanitarian supplies to remote villages in Honduras that were not accessible by conventional vehicles.[76] In November 2009, the 8th SO Squadron and its six CV-22s returned from a three-month deployment in Iraq.[77]
The first possible combat loss of an Osprey occurred on 9 April, 2010, as a CV-22 went down near Qalat, Zabul Province, Afghanistan, killing four.[78][79]
Potential operators
In 1999 the V-22 was studied for use in the United Kingdom's Royal Navy,[80] it has been raised several times as a candidate for the role of Maritime Airborne Surveillance and Control (MASC).[81]
Israel had shown interest in the purchase of MV-22s, but no order was placed.[82][83] Flightglobal reported in late 2009 that Israel has decided to wait for the CH-53K instead.[84]
The V-22 Osprey is a candidate for the Norwegian All Weather Search and Rescue Helicopter (NAWSARH) that is planned to replace the Westland Sea King Mk.43B of the Royal Norwegian Air Force in 2015.[85] The other candidates for the NAWSARH contract of 10-12 helicopters are AgustaWestland AW101 Merlin, Eurocopter EC225, NHIndustries NH90 and Sikorsky S-92.[86]
Bell Boeing has made an unsolicited offer of the V-22 for US Army medical evacuation needs.[87] However the Joint Personnel Recovery Agency issued a report that said that a common helicopter design would be needed for both combat recovery and medical evacuation and that the V-22 would not be suitable for recovery missions because of the difficulty of hoist operations and lack of self-defense capabilities.[88]
The US Navy remains a potential user of the V-22, but its role and mission with the Navy remains unclear. The latest proposal is to replace the C-2 Greyhound with the V-22 in the fleet logistics role. The V-22 would have the advantage of being able to land on and support non-carriers with rapid delivery of supplies and people between the ships of a taskforce or to ships on patrol beyond helicopter range.[89] Loren B. Thompson of the Lexington Institute has suggested V-22s for use in combat search and rescue and Marine One VIP transport, which also need replacement aircraft.[90]
Variants
• V-22A
•• Pre-production full-scale development aircraft used for flight testing. These are unofficially considered A-variants after 1993 redesign.[91]
• HV-22
•• The U.S. Navy considered an HV-22 to provide combat search and rescue, delivery and retrieval of special warfare teams along with fleet logistic support transport. However, it chose the MH-60S for this role in 1992.[92]
• SV-22
•• The proposed anti-submarine warfare Navy variant. The Navy studied the SV-22 in the 1980s to replace S-3 and SH-2 aircraft.[93]
• MV-22B
•• Basic U.S. Marine Corps transport; original requirement for 552 (now 360). The Marine Corps is the lead service in the development of the V-22 Osprey. The Marine Corps variant, the MV-22B, is an assault transport for troops, equipment and supplies, capable of operating from ships or from expeditionary airfields ashore. It is replacing the Marine Corps' CH-46E[57] and CH-53D.[94]
• CV-22B
•• Air Force variant for the U.S. Special Operations Command (USSOCOM). It will conduct long-range, special operations missions, and is equipped with extra fuel tanks and terrain-following radar.[95][96]

Notable accidents
Main article: Accidents and incidents involving the V-22 Osprey
From 1991 to 2000 there were four significant crashes, and a total of 30 fatalities, during testing.[32] Since becoming operational in 2007, the V-22 has had one possible combat loss due to an unknown cause, no losses due to accidents, and seven other notable, but minor, incidents.
• On 11 June 1991, a mis-wired flight control system led to two minor injuries when the left nacelle struck the ground while the aircraft was hovering 15 feet (4.6 m) in the air, causing it to bounce and catch fire.[97]
• On 20 July 1992, a leaking gearbox led to a fire in the right nacelle, causing the aircraft to drop into the Potomac River in front of an audience of Congressmen and other government officials at Quantico, killing all seven on board and grounding the aircraft for 11 months.[98]
• On 8 April 2000, a V-22 loaded with Marines to simulate a rescue, attempted to land at Marana Northwest Regional Airport in Arizona, stalled when its right rotor entered vortex ring state, rolled over, crashed, and exploded, killing all 19 on board.[37]
• On 11 December 2000, after a catastrophic hydraulic leak and subsequent software instrument failure, a V-22 fell 1,600 feet (490 m) into a forest in Jacksonville, North Carolina, killing all four aboard. This caused the Marine Corps to ground their fleet of eight V-22s, the second grounding that year.[99][100]

Tutorial on Instructables: www.instructables.com/id/Functional-LEGO-Nutcrackers/
With a simple pull of the lever, these decorative figures can open and close their jaws like authentic nutcrackers!
Both of these models were built in the recent weeks leading up to Christmas. The design was pretty straightforward, but two major issues were making the faces look good, and finally getting the hats right. In fact, the green nutcracker's crown took the longest to figure out, and was finally made with hinge plates.
As mentioned in the tutorial, although these can in fact function as real nutcrackers, they're somewhat rickety and best suited for holiday decorations.
The design and modular functionality of this set is unparalleled. The two cockpits detached from the center leaving a base behind. The top two sections also detached and could be reattached to the cockpits creating two ships with a little finagling of the tires. There was so much that you could do with this set. I toyed around (pun intended) with doing a whole Febrovery month based on this single set….but I figured I would wait for a 28 day Febrovery for that. This set is a perfect companion to the Alien Moon Stalker released the following year. I love the color scheme on both of them.
F225 universal agricultural tractor as of 1962. Includes two cylinder engine, two speed transmission, drive shafts, working steering, lifting arrangement. Can be configured as tipper, front loader with digger or fork. There was also a sowing machine and a mower for it.
Editor's Note: Hey Flickr friends, I thought all of you would like this one. The text from NASA goes into some great detail about new methods of photography from the Space Station. Happy weekend!
A test photo of British Columbia's snow-capped west coast mountains is the first official image taken from the International Space Station's new Window Observational Research Facility, or WORF.
The image was taken to test the functionality of the control computer and camera associated with EarthKAM, an educational outreach project that allows Earth bound middle school students to take pictures of our home planet from the unique perspective of the space station, 220 miles above the Earth's surface. WORF was delivered to the station on the STS-131 mission of space shuttle Discovery in April 2010.
EarthKAM uses a Nikon D2X digital camera, and was set up in the WORF by Expedition 26 NASA flight engineer Cady Coleman on Jan. 17. EarthKAM ground controllers took the test photo. Expedition 26 also includes Commander Scott Kelly of NASA, European Space Agency astronaut Paolo Nespoli, and Russian cosmonauts Oleg Skripochka, Alexander Kaleri and Dmitry Kontratyev.
The test photo, designated ISS EarthKAM Image Winter 2011 #9362, is of an area of British Columbia, Canada, just north of Vancouver Island. The center point of the photo is 51 degrees, 48 minutes north and 127 degrees, 54 minutes west. Visible in the photo are Calvert and Hecate Islands on the Canadian coast and the southern portion of Hunter Island. Also visible are glaciers of the Ha-iltzuk Icefield near the 8,720-foot-tall -- 2,658-meter-tall -- Mount Somolenko. Mount Somolenko is a volcanic peak in southwestern British Columbia, that lies in a circular volcanic depression in the Pacific Ranges of the Coast Mountains called the Silverthrone Caldera.
While this isn't a particularly unique Earth observation image, it is notable that even though it was taken with a wider angle, 50mm lens and covers an area 124 miles/200 kilometers, by 83 miles/134 kilometers, it can be enlarged by more than 400 percent while keeping features in the photo identifiable. This is made possible by the high-quality optics of the Earth-facing window of the Destiny Laboratory, which was launched on Feb. 7, 2001.
The installation of WORF allowed removal of an internal "scratch pane" that has reduced the quality of images taken though the window. WORF also provides a highly stable mounting platform to hold cameras and sensors rock steady at the window, as well as the power, command, data, and cooling connections needed for their operation.
"With the WORF finally in place we can now for the first time make full use of the investment we made in having an optical quality window onboard the station for Earth science and observation," said former astronaut Mario Runco, who was part of the design and development teams for the Destiny window and WORF, and now serves as NASA's lead for Spacecraft Window Optics and Window/WORF Utilization at NASA's Johnson Space Center, Houston.
"We are very excited to have a new camera system that appears to be functional and taking incredible images," said Karen Flammer, who manages EarthKAM operations at the University of California, can Diego. "The first student images were taken by Parkview Montessori in the Jackson-Madison County (Tenn.) School System, and Public School 229 - Dyker in Brooklyn, N.Y., part of the New York City Department of Education.
Parkview teacher Vickie LeCroy's students plan to study landforms, such as islands, mountains and deserts in the image they took of Mexico, and Dyker teacher Camille Fratantoni’s students plan to enrich their studies of earth science and learn more about NASA missions.
In addition to their educational outreach role with EarthKAM, the combination of the window and WORF adds to the station's capabilities as an Earth science remote sensing platform for high-resolution cameras and multi and hyperspectral imagers. Images from space have many applications, such as in the study of climate and meteorology; oceanography; geology and volcanology; coastal, agricultural, ranch and forestry management; and disaster assessments and management.
