...15 years younger. I haven't been on a plane yet. I was in college; I was dealing with Integrals, and control systems, and Fourier calculations, and a few classmates who's only forte was bragging -- and technical drawing, after the drawing classes were gone all they can do was look "cool"(aside from consistently dealing with failing grades) at least -- for the most of them; I only have 1% of the enemies that I have now, but I have more friends now though; No one has betrayed me yet; I have owned a film camera for three years when I last walked in this city; Dolphins greeted the boat as it approaches the city's port; There was less traffic; Some of my relatives told me the school in front of this obelisk is good, and it was even considered that maybe I can study here someday, but it was not to be; The only mall in this place was called Lim Ket Kai; I had a simpler life back then; The only money I earn is the bits of my daily allowance -- and the tuition fee refund I got from school; I was thinner, more physically fit, and maybe more deadly, and can outrun, out swim, outplay and out jump almost anyone I knew.
When I departed this city the last time, my relatives told me "balik balik unya pohon...", a Philippine dialect term for something like "come back here soon"... and now I realized, that "soon" was to be 15 years later. Times have changed now... and all those memories still percolating in my mind -- that was 15 years ago when time seemed to have been crawling all along. And the funny part of it is... all of my companions on this trip now were still in high school(probably elementary) during the time when I last came here.

Soybeans are grown as part of variety trials at the Fisher Delta Research Center.
The soils and topography of southeast Missouri offer researchers a unique opportunity to study cotton and rice production and irrigation. Researchers also are evaluating better soybean cropping systems, and weed, insect and disease-control systems. Three locations make up Fisher Delta Research Center’s 1,078 acres in a 12-county area that forms the Missouri Bootheel. Scientists at the center have gained recognition for developing improved soybean varieties, especially those with soybean cyst nematode resistance and maintain a regional soil and plant-testing laboratory.

NASA's Human Robotic Systems Project, part of the agency's Exploration Technology Development Program, focused on human and robotic mobility systems for the moon, but also looked at communication and command and control systems that will connect the explorers with Earth and each other. The Moses Lake dunes provided a wide variety of soil consistencies and terrain that allowed the team to put prototype scout robots, rovers, cargo carriers, cranes and spacesuits through tests in a harsh and changing environment.
The prototype tests will be used to inform developers of specific requirements needed in lunar surface support systems for the Constellation Program. The program is building the launch vehicles and spacecraft that will take a new generation of explorers to the moon, as well as lunar landers, habitats, life support systems, vehicles and robots to support them. A ground control team located thousands of miles away at Johnson operated the robots and coordinated the movements of the suited explorers.
NASA's Ames Research Center in Moffett Field, Calif., tested two K10 rovers that surveyed simulated lunar landing sites and built topographic and panoramic 3-D terrain models. One rover used a ground-penetrating radar to assess subsurface structures. The other used a 3-D scanning laser system known as LIDAR to create topographic maps. The scout robots are designed to perform highly repetitive and long-duration tasks, such as site mapping and science reconnaissance.JPL tested two ATHLETE cargo-moving rovers. Each rover has six legs capable of rolling or walking over extremely rough or steep terrain. This will allow robotic or human missions on the surface of the moon to load, manipulate, deposit and transport payloads to desired sites. The team includes members from Johnson, Ames, Stanford University and The Boeing Co. of Chicago.
NASA's Glenn Research Center in Cleveland, and Carnegie Mellon University of Pittsburgh tested an autonomous drilling rover that could be used to search for valuable resources under the lunar surface in the moon's polar regions. The team also includes members from Ames, Johnson, NASA's Kennedy Space Center, the Canadian Space Agency and the Centre for Advanced Technology Inc. in Sudbury, Ontario.

I have found it very difficult to get information on the ZF gearbox and its control system. ZF are not intrested in helping much and specialists are not willing to help unless they are being hired at cost to do the work. None of this was any use to me as I want to learn the systems of the bus and how to repair them myself as for me this is the bit I enjoy the most. After a lot of phoning I finally managed to get sent a wiring diagram for the ZF EST18 system. This allowed me to carefully trace the 12 chopped gear selector wires. Graham had recovered a working gear selector for the plug and he had the sense to locate and save the multiplug. Using the old plug I was able to buy new pins which will allow me to repair the wiring loom on the bus. This will mean the gear selector will simply plug in "IF" I get the wiring correct.
Update Dec. 21, 2021 - A composite showing these, as well as images in other wavelengths, that have been stacked and processed can be found the the link attached here - www.flickr.com/photos/homcavobservatory/51761604013/
With a storm last night which knocked out the power here, and another due to move into our area tonight and bring with it snow & ice; I was lucky to be able to catch the Sun during the short break between the cloud banks this morning.
Solar activity is beginning to increase again with the appearance of Active Regions 2907, 2908 & 2909 over the past few days forming a 'chain-like' line across the visible surface (left to right respectively) for what a quick estimate in comparison to the Sun's overall diameter seems to indicate is over 240,000 miles (nearly 400,000 km) long ! In addition, a new region (AR2911), has become visible on the upper left limb.
The attached composite of single frame images (grabbed from recorded videos) show an overall full disk 'reference image' and 'close-ups' of both the AR 2907-2908-2909 'chain' as well as the newly appearing AR2911.
They were shot thru homemade Baader (visual grade material) white-light solar filters on an 80mm, f/5 refractor and a vintage 1970, 8-inch, f/7 Criterion newtonian reflector. Both used a ZWO ASI290MC planetary camera / autoguider controlled by SharpCap Pro, and the scopes were mounted on & tracked via a Losmandy G-11 running a Gemini 2 control system.
With the seeing varying somewhere between horrible & terrible ;) , and the full disk being a composite of only two single frames (left & right halves) and
the 8-inch shots are individual single frames; they all contain quite a bit of noise. Having taken thousands of such frames today through both luminance filters as shown here, and with the 8-inch employing Ultraviolet, Infrared & Methane filters as well;
I'm looking forward to seeing what details I can pull out of the data once it is stacked & processed.
As is typical for most of my astronomical endeavors, once again today I've been enjoying musical accompaniment - in this case in the form of a wonderful concert by the Allman Brothers from the Fillmore East (shown here doing an excellent rendition of 'Whipping Post'). Having been a fan of their music for decades, I actually have this 'Live At The Fillmore East' double album in my vinyl collection (a digital version of which I am listening to as I type this :) ) . I was fortunate to catch them in concert back in the late 90's at a ski resort in our area where they put on a fabulous show (albeit given the jamming they are noted for, at times it seemed like one single three-hour long song :) ) !
As a side note it was reported that Active Region produced a M1 class solar flare at 0051 UT today. There are now several groups able to produce flares of this magnitude (or possibly higher if we're lucky ? ;) ) that should be moving into geomagnetic effective positions soon. In addition to my ever-present wish for Peace On Earth; it would be nice if Santa could bring us a wonderful auroral display for the holidays ;) - Stay Tuned !!!
The Erieye radar system is an Airborne Early Warning and Control System (AEW&C) developed by Saab Electronic Defence Systems (formerly Ericsson Microwave Systems) of Sweden. It uses active electronically scanned array (AESA) technology. The Erieye is used on a variety of aircraft platforms, such as the Saab 340 and Embraer R-99. It has recently been implemented on the Bombardier Global 6000 aircraft as the Globaleye.
The Erieye Ground Interface Segment (EGIS; not to be confused with the Aegis combat system) is a major component of the software used by the Erieye system.
The radar provides 300 degree coverage and has an instrumental range of 450 km and detection range of 350 km in a dense hostile electronic warfare environment—in heavy radar clutter and at low target altitudes. In addition to this, the radar is also capable of identifying friends or foes, and has a sea surveillance mode.
The Erieye system has full interoperability with NATO air defence command and control systems.
Design
The Erieye AEW&C mission system radar is an active, phased-array, pulse-doppler sensor that can feed an onboard operator architecture or downlink data (via an associated datalink subsystem) to a ground-based air defence network. The system employs a large aperture, dual-sided antenna array housed in a dorsal 'plank' fairing. The antenna is fixed, and the beam is electronically scanned, which provides for improved detection and significantly enhanced tracking performance compared with radar-dome antenna systems. Erieye detects and tracks air and sea targets out to the horizon, and sometimes beyond this due to anomalous propagation — instrumented range has been measured at 450 kilometres (280 mi). Typical detection range against fighter-sized targets is approximately 425 kilometres (264 mi), in a 150° broadside sector, both sides of the aircraft. Outside these sectors, performance is reduced in forward and aft directions.
Other system features include: Adaptive waveform generation (including digital, phase-coded pulse compression); Signal processing and target tracking; track while scan (TWS); low side lobe values (throughout the system's angular coverage); low- and medium-pulse repetition frequency operating modes; frequency agility; Air-to-air and sea surveillance modes; and target radar cross-section display.
The radar operates as a medium- to high-PRF pulse-Doppler, solid-state radar, in E/F-band (3 GHz), incorporating 192 two-way transmit/receive modules that combine to produce a pencil beam, steered as required within the operating 150° sector each side of the aircraft (one side at a time). It is understood that Erieye has some ability to detect aircraft in the 30° sectors fore and aft of the aircraft heading, but has no track capability in this sector.
14.septembrī Starptautiskajā lidostā “Rīga” nosēdās NATO agrīnās brīdināšanas un kontroles sistēmas (Airborne Warning & Control System) lidmašīna, kas ieradusies no Gaisa spēku bāzes Geilenkirhenē, Vācijā.
Latvijā ieradās Sabiedroto spēku augstākās virspavēlniecības Eiropā komandiera vietnieks ģenerālis sers Džeimss Everards (James Everard) un NATO agrīnās brīdināšanas un kontroles spēku komandiere ģenerālmajore Davna Danlopa (Dawn M. Dunlop), pirms tam veicot novērošanas un gaisa telpas kontroles lidojumu no Gaisa spēku bāzes Gailenkirhenē līdz Rīgai.
AWACS ir vienīgie NATO īpašumā esošie gaisakuģi. NATO neizmanto kopējo finansējumu, lai pirktu militāro spēju platformas, proti, kuģus un tankus, jo tā ir katras dalībvalsts individuāla izvēle un atbildība.
Geilenkirhene ir galvenā bāzes vieta Eiropā AWACS lidojumiem, jo no 19 lidmašīnām, kas Eiropā veic lidojumus, 16 bāzējas tieši Geilenkirhenē, vēl trīs atrodas Vašingtonā Lielbritānijā.
Kopš Krimas aneksijas 2014. gadā tiek novērota arī Latvijas gaisa telpa. Reaģējot uz situāciju Ukrainā, NATO Ziemeļatlantijas padome 2014. gada 10. martā ieviesa atbalsta pasākumu plānu, tādējādi demonstrējot alianses vienotību un apņēmību aizsargāt sabiedrotos. Trīs dienas vēlāk, 13. martā, NATO atbalsta pasākumu programmas ietvaros notika pirmais NATO agrīnās brīdināšanas un kontroles sistēmas lidojums no NATO bāzes Geilenkirhenē, Vācijā.
Latvijā AWACS lidmašīna viesojusies divas reizes — 2004. gadā, pirms Latvijas iestāšanās NATO. Savukārt 2016. gada 11. oktobrī, pirmo reizi kopš iestāšanās NATO, Starptautiskajā lidostā “Rīga” piezemējās AWACS lidmašīna, tādējādi demonstrējot pasaulei NATO klātbūtni un lojalitāti Latvijai, Lietuvai, Igaunijai, Polijai un Rumānijai.
AWACS lidmašīnas kopš 2014. gada pavasara ir veikušas vairāk nekā 1000 novērošanas un gaisa telpas kontroles lidojumus.
Par AWACS
“E-3A Sentry” uzbūvēta uz «Boeing 707» bāzes. Lidmašīnas astes galā atrodas radars (tā diametrs 9 m), kas apgādā apkalpi ar datiem, ko analizē datori un citas elektroniskās iekārtas lidmašīnā.
Parasti lidmašīnas lido astoņas stundas aptuveni 10 km augstumā, nosedzot vairāk nekā 400 km novērojamās platības.
Maksimālais ātrums — 853 km/h. Degvielas ietilpība — 89 610 litri. Spēja lidot bez papildu uzpildes — 11 h. Šī modeļa lidmašīnām iespējama uzpilde gaisā, ko veic ar gaisa tankkuģa KC-135 palīdzību. Arī šī lidmašīna izvietota Geilenkirhenē, nodrošinot ilgstošu AWACS uzdevumu izpildi.
Ekipāža — 2 piloti, 1 lidojuma inženieris, 1 navigators, 12 apkalpes locekļi, no kuriem vairāki atrodas taktiskajā operāciju centrā. Modernizētajā AWACS versijā pilotu kabīnē paredzētas 3 vietas, jo tehnoloģiskās inovācijas aizstāj navigatoru.
Gaisakuģa garums — 46,61 m, augstums — 12,73 m, tukšas lidmašīnas masa — 78 000 kg, ekipētas — 147 420 kg.
AWACS nodrošina plaša spektra uzdevumu izpildi, piemēram, gaisa kontroli, pretterorisma akciju atbalstu, evakuācijas, agrās brīdi¬nāšanas un krīzes reaģēšanas operācijas.
AWACS bija svarīga loma NATO operācijās ASV pēc 2001. gada 11. septembra terorakta, pēc viesuļvētras “Katrina” 2005. gadā. Arī 2010. gada zemestrīces Haiti un plūdu seku novēršanā Pakistānā 2010. gadā. AWACS sniedz gaisa atbalstu, lai padarītu drošākus NATO samitus un svarīgus starptautiskus pasākumus, piemēram, ASV prezidenta vizīti 2016. gadā Vācijā, arī Eiropas futbola čempionātu 2016. gadā Francijā.

Well Control System
This picture shows the Well Control System that I designed for this home water system.
Modern electrical components were used with this system. As is used with old fashioned well control systems, simple relay logic was not used here.
Mario has been very helpful.
The column of lights in the box above the main cabinet shows the detailed status of the important Well Control System functions. These status lights can be very helpful for diagnosing water supply issues.
The loudspeaker on the upper left emits a very loud and shrill sound when the water in the cistern is too low. This sound can be heard anywhere in the house. The system must be turned off and the problem must be resolved before the system can be used again.
The power control box on the upper right provides fusing and a method to turn the entire Well Control System on and off.

During the modernisation of the assembly hall, Colt installed 700 large Solarfin shading louvres to optimise the flow of light and heat energy into the building, offering a substantial saving with regards to energy costs on cooling during the summer months. The louvres are designed to follow the path of the sun, and are moved by a PIA control system.

"Apollo spacecraft simulator built by Honeywell for testing of its Apollo Stabilization and Control System (SCS) was described as the largest and most sensitive device of its kind. Cold-gas reaction jets maneuvered the huge circular platform at the company's Aeronautical Division, Minneapolis, as it simulated characteristics of the Apollo command module in flight to and from the moon. A single stainless steel bearing (center) resting on a paper-thin cushion of gas supported some eight metric tons (nine U.S. tons) of equipment, virtually isolating the platform from friction and vibration. Engineer Leonard Aske inspected one of the jets (upper right) while engineer Dick McKinley adjusted part of the bearing mechanism. Both SCS and simulator were developed for North American Aviation under NASA guidance."

“Strap-on solid fuel rockets would provide the additional boost needed for the Saturn IB to put a high-flying astronomical telescope into orbit in a future mission envisioned by Chrysler Corp. officials at Michoud [said].”
When you take a closer look at this, it’s really a beautiful & detailed work. Unfortunately, no signature is visible. And, if indeed by a Chrysler Corp. artist, identification will remain elusive, if not impossible.
Although...although...if by some chance it's a NASA work, there may be some similarity to Rosemary Dobbins' works:

Object Details: Sunspots (right) AR2740 & (left, on limb) AR2741 as they currently appear from our home's observatory in upstate, NY. Both are larger than the Earth and AR2740 is actually the return of the same region which transited a few weeks ago and has survived fairly intact. (Images of it from the previous rotation, when it was numbered as AR2738, can be found at the following links www.flickr.com/photos/homcavobservatory/46738306615/
www.flickr.com/photos/homcavobservatory/40615502103/ ).
Not very active during it's last transit, this one may differ in that although having just rotated into visibility during the last few days, it has already released an M1 class flare. Hopefully it, or AR2741, will become reasonably geo-effective and bring us an auroral display in the near future - stay tuned!
Update May 10, 2019 - Images taken on May 8, 2019 can be found at the attached link - www.flickr.com/photos/homcavobservatory/33943442198/
Image Details: Image Details: Taken by Jay Edwards at the HomCav Observatory on May 6, 2019 using a ZWO ASI290MC planetary camera / auto-guider through (left) an an Orion 80mm, f/6 carbon-fiber apochromatic triplet refractor (i.e. an ED80T CF). and (right) an 8-in, f/7 Criterion newtonian reflector. The 8-inch scope used a homemade off-axis Baader material white-light solar filter, while the 80mm was fitted with a full aperture Kendrick white-light filter. These scopes were tracked using a Losmandy G-11 mount running a Gemini 2 control system.
As presented here the images have been processed & cropped slightly colorized for aesthetics, and the entire composite has been resized down to HD resolution.
Object Details: Eight numbered sunspots are currently on the Sun's Earth facing side, the most in over 4 years. The attached composite shows how four of the largest appeared last Friday thru both a shorter focal length & a long focal-length scope, albeit with the seeing varying somewhere between terrible & horrible - lol.
At the time, the newest, AR2911, had just became visible on the limb and displayed quite a lot of faculae (i.e. the brighter, hotter areas surrounding the spot), while sunspots AR2907, AR2908 & AR2909 formed a 'chain' over 240,000 miles (nearly 400,000 km) long !
Image Details: Taken as short video clips from which selected frames are stacked and processed, given the camera sensor's crop factor, the 80mm 'full-disk' image is a composite of two fovs while that, and all the 8-inch images, are resized down to approximately half their original size / resolution.
In addition to the Baader white-light solar filters and luminance filters, as can be seen at bottom, I also utilized Methane (CH4), Ultraviolet, & Infrared filters (in place of the lum filter) for additional shots thru the 8-inch newt.
As is often the case in our observatory, the scopes were mounted on and tracked with a Losmandy G-11 running a Gemini 2 control system. Processed using a combination of Registax & Paint Shop Pro, as presented here the entire composite has been resized down to 3x HD resolution.
It should be noted that Spaceweather reported today (Dec. 21) that on December 20th at 11:36 UT sunspot AR2908 released an M1.9-class solar flare which seems to have produced a somewhat Earth-directed Coronal Mass Ejection. Impact from this CME is expected to make a glancing blow of Earth's magnetic field and thus MAY produce minor G1-class geomagnetic activity on December 23rd - stay tuned !
Wishing a Happy Solstice To All !!!

“E-3A Sentry” uzbūvēta uz «Boeing 707» bāzes. Lidmašīnas astes galā atrodas radars (tā diametrs 9 m), kas apgādā apkalpi ar datiem, ko analizē datori un citas elektroniskās iekārtas lidmašīnā.
Parasti lidmašīnas lido astoņas stundas aptuveni 10 km augstumā, nosedzot vairāk nekā 400 km novērojamās platības.
Maksimālais ātrums — 853 km/h. Degvielas ietilpība — 89 610 litri. Spēja lidot bez papildu uzpildes — 11 h. Šī modeļa lidmašīnām iespējama uzpilde gaisā, ko veic ar gaisa tankkuģa KC-135 palīdzību. Arī šī lidmašīna izvietota Geilenkirhenē, nodrošinot ilgstošu AWACS uzdevumu izpildi.
Ekipāža — 2 piloti, 1 lidojuma inženieris, 1 navigators, 12 apkalpes locekļi, no kuriem vairāki atrodas taktiskajā operāciju centrā. Modernizētajā AWACS versijā pilotu kabīnē paredzētas 3 vietas, jo tehnoloģiskās inovācijas aizstāj navigatoru.
Gaisakuģa garums — 46,61 m, augstums — 12,73 m, tukšas lidmašīnas masa — 78 000 kg, ekipētas — 147 420 kg.
AWACS nodrošina plaša spektra uzdevumu izpildi, piemēram, gaisa kontroli, pretterorisma akciju atbalstu, evakuācijas, agrās brīdi¬nāšanas un krīzes reaģēšanas operācijas.
AWACS bija svarīga loma NATO operācijās ASV pēc 2001. gada 11. septembra terorakta, pēc viesuļvētras “Katrina” 2005. gadā. Arī 2010. gada zemestrīces Haiti un plūdu seku novēršanā Pakistānā 2010. gadā. AWACS sniedz gaisa atbalstu, lai padarītu drošākus NATO samitus un svarīgus starptautiskus pasākumus, piemēram, ASV prezidenta vizīti 2016. gadā Vācijā, arī Eiropas futbola čempionātu 2016. gadā Francijā.

The threat of Soviet bomber attacks on the United States put the US Air Force into an unenviable position in the late 1940s: it lacked a jet all-weather interceptor. The only interceptor then in service was the F-82 Twin Mustang, which could not be expected to keep up with any jet bomber project the Soviet Union might be developing. Both Curtiss and Northrop were working on new aircraft, the XF-87 Blackhawk and XF-89 Scorpion, but the former was cancelled due to poor performance and the latter was plagued with problems. The USAF needed interceptors in a hurry, so a crash program was started to convert existing fighter designs, culminating in the F-95 (later F-86D) Sabre Dog and the F-94 Starfire.
Of the two, the F-94 was considered the easier conversion. The successful T-33A Shooting Star trainer would be the basis for the design, as it could easily accommodate the electronics needed for the all-weather interceptor mission. It lacked a radar, but this could be mounted in an extended nose; armament would be similar to the F-80 fighter, with four machine guns. As the design progressed, however, Lockheed’s chief designer, Clarence “Kelly” Johnson, realized that the J33 engine of the T-33 simply would not get the much heavier F-94 into the air. An afterburner had to be installed in the J33, which meant a complete redesign of the rear fuselage, which also meant lengthening the fuselage, enlarging the tail, and changing the nose profile. The result was indeed a completely new aircraft.
Nonetheless, it was ready nearly as quickly as hoped, with the first YF-94A flying in April 1949. After a few minor modifications to the engine, the Starfire was placed in production with an initial order of 109 aircraft; after the detonation of the first Soviet atomic bomb later that year, procurement was raised to 368 aircraft.
In service, the F-94A was loathed by its crews. The engine was subject to catastrophic failure, the fuel system was unreliable, and the fire control system was worse. Ejecting from the narrow-cockpit F-94A was often lethal, as the seats barely cleared the sides of the aircraft and sometimes did not clear the higher tail. Finally, the Starfire was difficult to control at altitude and had a tendency to go into spins. Luckily, the F-94B solved the majority of these problems, with an upgraded engine, better fire control, and wider cockpit. Performance was still limited, but it was all that was available.
When North Korean and Chinese propeller fighters began night harassment attacks against American bases in South Korea during the latter years of the Korean War, F-94Bs were deployed to Japan and South Korea to deal with these aircraft. While the Starfires were able to score some successes, they were simply too fast for the job: it was very difficult for a near-supersonic fighter to shoot down Polikarpov Po-2 biplanes that could barely reach a hundred miles an hour; one F-94 was lost when it accidentally collided with the Po-2 it was trying to shoot down. As a result, US Navy F4U Corsairs had to be brought in to finally end these attacks.
Since the gun armament of the F-94A/B was considered inadequate against large bombers, Lockheed proposed an all-rocket armed version, the F-94C. The company went further than revising the armament: it was virtually a new aircraft, with a thinner wing, revised tail, more fuel, upgraded radar, dragchute (the first fitted to an American aircraft), and most importantly, a much larger and efficient J48 engine. The 24 rockets were clustered around the radar.
At first, the USAF was not interested, as the F-89 and F-86D was entering service, but Lockheed persisted, developing the aircraft at the company’s own expense, and the performance of the prototype in January 1950 was enough for the USAF to purchase it as the F-97—though this was later changed back to F-94C to avoid the program being cut by Congress (which was more reluctant to fund a new aircraft). While the F-94C was not without its problems—the rockets tended to cause the engine to flame out when fired and would blind the pilot if fired at night—it benefited from all the lessons learned in the F-94A/B series, and was popular with its crews. To further increase its armament, two wing pods were added with yet more rockets, raising the number to 48.
F-94Cs replaced earlier variants beginning in 1951, and was reliable enough that it would serve for eight years, which was a considerably long time in the 1950s, when many aircraft did not serve for long due to the rapid progress of technology. It began to be retired in 1958 in favor of the F-102 and F-106, with the last F-94C leaving the Air National Guard in 1960. 855 Starfires were built; 17 survive today in museums and as gate guards.
49-2500 is a F-94A...sort of. It never served in any USAF frontline or ANG unit; it was delivered directly to the Air Research and Development Center (ARDC) at Wright-Patterson AFB, Ohio as a testbed, then loaned to Cornell University to test stability at high speeds--because the F-94A was so unstable, it was well suited to this work. Possibly for this reason, it was fitted with the nose and cockpit section of a T-33A, making 49-2500 a Frankenstein. During its time at Cornell, it was flown by several test pilots, including Neil Armstrong.
In 1958, no longer needed, 49-2500 was donated to the Buffalo, New York city government and turned into a playground. Some years later, it was salvaged and restored by the Niagara Falls Aerospace Museum, and was possibly also displayed at the Museum of Aviation at Robins AFB, Georgia. Finally, it made its way to the Castle Air Museum, where 49-2500 resides today.
At first I had no idea what this was--a T-33 with a F-94 tail, or a F-94 with a T-33 nose? Luckily for posterity, this odd aircraft has been preserved in the markings of ARDC.

Taken at Middlewood Ambulance Station Sheffield.
I work for Yorkshire Ambulance Service on the RRVs in and around the city of Sheffield in South Yorkshire.
It’s a great job and I feel very honoured to be able to help people at their point of need.
Check out the website for all sorts of info re YAS and the work we do.
Six advisory signs will operate through a central control system to provide real-time train crossing information — indicating if the crossing is open or closed — so drivers can make informed decisions for travel in Langley, Surrey and the Township of Langley. The signs will specify the train’s location and travel direction, enabling drivers to use alternate crossing options at adjacent railway overpasses, in order to avoid traffic delays. In addition to reducing traffic congestion and minimizing greenhouse gas emissions due to decreased vehicle idling times, the signs will increase travel efficiency and mobility for emergency vehicles.
From Ashley D:
Picture #1 tries to demonstrate the way in which the door access control systems, which is a stable artifact, in South Hall is, in my opinion, broken and not necessarily used in an uncommon way. The intent behind installing these devices is to restrict access to iSchool staff, faculty and students only. It is the only logical reason for investing in these devices.
As the intent is to restrict access, the 2 options available are to have human security personnel or these devices.
The advantage of these devices is that they are less intrusive and non-discriminatory. Hence, it seems reasonable to delegate this job to a non-human artifact.
However, the trade-off is that they do not fulfill their task as expected. It is very possible to allow access to outsiders, which is why at the start of each semester we get an email from Meg reminding us about our responsibilities towards taking care of the lounges. I think this demonstrates the 'shift of responsibility' aspect with an emphasis on each human entities moral values.
I use this example because in my previous place of employment a similar system was in place, but there were human guards, as well as machines, to ensure that each and every person swiped in before entering.
What (missing) entities must it be enrolled with to make it what it more typically is?
The missing entities that could be enrolled are both technical artifacts. Something like an automatic door and a sensor, like the one placed near the vending machine (Picture #2) to detect the presence of more than one person, could be used to supplement the social and moral responsibilities of the human entities thereby enforcing a moral code on everyone without discrimination. Something similar to the seat belt.
14.septembrī Starptautiskajā lidostā “Rīga” nosēdās NATO agrīnās brīdināšanas un kontroles sistēmas (Airborne Warning & Control System) lidmašīna, kas ieradusies no Gaisa spēku bāzes Geilenkirhenē, Vācijā.
Latvijā ieradās Sabiedroto spēku augstākās virspavēlniecības Eiropā komandiera vietnieks ģenerālis sers Džeimss Everards (James Everard) un NATO agrīnās brīdināšanas un kontroles spēku komandiere ģenerālmajore Davna Danlopa (Dawn M. Dunlop), pirms tam veicot novērošanas un gaisa telpas kontroles lidojumu no Gaisa spēku bāzes Gailenkirhenē līdz Rīgai.
AWACS ir vienīgie NATO īpašumā esošie gaisakuģi. NATO neizmanto kopējo finansējumu, lai pirktu militāro spēju platformas, proti, kuģus un tankus, jo tā ir katras dalībvalsts individuāla izvēle un atbildība.
Geilenkirhene ir galvenā bāzes vieta Eiropā AWACS lidojumiem, jo no 19 lidmašīnām, kas Eiropā veic lidojumus, 16 bāzējas tieši Geilenkirhenē, vēl trīs atrodas Vašingtonā Lielbritānijā.
Kopš Krimas aneksijas 2014. gadā tiek novērota arī Latvijas gaisa telpa. Reaģējot uz situāciju Ukrainā, NATO Ziemeļatlantijas padome 2014. gada 10. martā ieviesa atbalsta pasākumu plānu, tādējādi demonstrējot alianses vienotību un apņēmību aizsargāt sabiedrotos. Trīs dienas vēlāk, 13. martā, NATO atbalsta pasākumu programmas ietvaros notika pirmais NATO agrīnās brīdināšanas un kontroles sistēmas lidojums no NATO bāzes Geilenkirhenē, Vācijā.
Latvijā AWACS lidmašīna viesojusies divas reizes — 2004. gadā, pirms Latvijas iestāšanās NATO. Savukārt 2016. gada 11. oktobrī, pirmo reizi kopš iestāšanās NATO, Starptautiskajā lidostā “Rīga” piezemējās AWACS lidmašīna, tādējādi demonstrējot pasaulei NATO klātbūtni un lojalitāti Latvijai, Lietuvai, Igaunijai, Polijai un Rumānijai.

Very little is known about the Gundrarian Conglomerate. It is a very secretive faction within the galaxy, allowing almost no trade or travel within its borders. No military vessels belonging to another faction are known to have ever travelled into Gundrarian space and come out.
A Vamyr battle flotilla is known to have entered a Gundrarian-controlled system, but the Confederate scout ships reported none had exited. When any trade is made with the Gundrarian Conglomerate, it is usually for exceedingly rare items or materials, which are then put onto unmanned ships and sent into Conglomerate space, where they are never seen or heard from again. The Gundrarians always pay in full, upfront, for the enitre cargo AND the ship it is sent on. No one has yet to try and renege or cheat on a contract with the Gundrarian Conglomerate.
Consequently, what is known about the Traveler-class heavy frigate is known only through careful observation, mostly by the Confederation Of Republic Systems and the Royal Empire, both of which border the few systems occupied by the Gundrarian Conglomerate. Although sized like a destroyer, it has very few visible weapons, and so was classified as a heavy frigate. It was known to be very fast, however the strength of its defenses were not well known until the Skirmish at Adriak.
A wealthy trading outpost, Adriak was the site of a massive Vamyr attack, a full battle fleet intent on ransacking the outpost and destroying it, weaking the economic ties it had to the rest of the galaxy. A single Traveler was in-system, negotiating for a trade agreement, when the attack happened. By chance, two small battle groups, one each from the Royal Empire and the Confederation of Republic Systems, were conducting a military exercise in the system. They moved to engage the Vamyr ships and allow all civilian and private craft a chance to escape. However, they were too far away, and the Vamyr started opening fire, destroying everything in site, including the Adrika-1 space station, the lifeblood of the system. The sole Traveler-class, apparently to protect the fleeing civilian vessels, hung back, attracting the fire of the Vamyr ships.
It sustained a tremendous amount of firepower, more than even a larger ship than it with full power to shields should have been able to withstand, and did so for far longer than it should have, until the Allied ships came to the rescue, allowing it to escape. After the battle, with the Vamyr refusing to pay compensations, the Gundrarians offered to pay to rebuild the Adrika-1 for a discount on future trade agreements. The Adriak system's government readily agreed.
The Traveler-class is the only known Gundrarian ship type, and no Traveler has ever been observed to commit acts of aggression. While the peace between the Gundrarian Conglomerate and the rest of the galaxy is uneasy, it is most welcome.

"The deployment of the flag of the United States on the surface of the moon is captured on film during the first Apollo 11 lunar landing mission. Here, astronaut Neil A. Armstrong, commander, stands on the left at the flag's staff. Astronaut Edwin E. Aldrin Jr., lunar module pilot, is also pictured. The picture was taken from film exposed by the 16mm Data Acquisition Camera (DAC) which was mounted in the Lunar Module (LM). While astronauts Armstrong and Aldrin descended in the Lunar Module (LM) "Eagle" to explore the Sea of Tranquility region of the moon, astronaut Michael Collins, command module pilot, remained with the Command and Service Modules (CSM) "Columbia" in lunar orbit."

Apollo 14 closeout photo of Reaction Control System (RCS) Quadrant no. 4, LM-8 (Antares). Photograph was taken 27 January, 1971, inside the Spacecraft-Lunar Module Adapter (SLA), at Launch Complex 39A (LC-39A). The inner surface of an SLA panel is visible to the left, the white circular S-Band Steerable Antenna is to the back, and the triangular outline & protective cover of/over the Lunar Module Pilot's (LMP) window can be made out at the upper right corner. Excellent detail is visible on three of the four Marquardt R-4D thruster nozzles.
This photo was probably taken during the same closeout photo documentation ‘session’:

Object Details: As weather allows I continue to follow the progression of the two large sunspots currently visible. To that end, the attached is a composite of images showing the Sun as it appeared two days ago from our home's observatory. At the time these images were taken, AR2741 was moving toward a more potentially geo-effective position, while AR2740 continued to break apart with a light bridge visible between the two largest portions of the umbra.
Note: Although even when not raining here, the transparency & seeing conditions have naturally varied greatly from day to day for those times that I have been able to image these groups during the past month. Although some of the images taken on days of better seeing could have been processed more aggressively to bring out additional detail, I've purposely tried to keep the post-processing fairly similar for all solar images taken during this period. Albeit, this has also somewhat limited the processing's ability to enhance detail to that of the lowest common denominator of atmospheric conditions, I believe it is best from the standpoint of comparison.
Therefore, with the goal of illustrating differences in appearance over time in mind; additional images of these groups over the last few weeks using the same equipment can be found at the following links:

(Note: Having survived an entire rotation around the Sun fairly intact, the following images were taken when AR2740 was visible during the previous rotation, and as is traditional, carried a different designation (i.e. AR2738))

Image Details: The images which make up the attached composite were taken by Jay Edwards at the HomCav Observatory on May 8, 2019 using a ZWO ASI290MC planetary camera / auto-guider through (left) an an Orion 80mm, f/6 carbon-fiber apochromatic triplet refractor (i.e. an ED80T CF). and (right) an 8-in, f/7 Criterion newtonian reflector. The 8-inch scope used a homemade off-axis Baader material white-light solar filter, while the 80mm was fitted with a full aperture Kendrick white-light filter. These scopes were tracked using a Losmandy G-11 mount running a Gemini 2 control system.
As presented here the images have been processed & cropped slightly colorized for aesthetics, and the entire composite has been resized down to HD resolution.
Extra Thick, 1/2" or more deep, acrylic letters mounted with drilled studs and stand offs providing a nice shadow effect. Colored logo and text provides a good contrast with the off-white interior wall. Letters were mounted high towards the ceiling so that the signage is visible from all cubicles inside the big working area.
