The Cold War resulted in a rather large number of interesting military research programs. One of these with which I'm familiar is the
Aircraft Nuclear Propulsion program, which ran from 1946 to 1961. The basic idea? Modify a bomber (such as a
B-36 bomber), creating an aircraft that could theoretically remain aloft for weeks at a time without refueling, much like ballistic submarines? The challenge? Shielding. Shielding the reactor alone would make the aircraft prohibitively heavy, so the idea was to primarily shield the crew compartment instead of the reactor. However, to study the concept, and evaluate various lightweight shielding concepts, two very novel and unique nuclear reactors were built at
Oak Ridge National Laboratory: the
Bulk Shielding Reactor, a novel "swimming pool reactor", and the
Tower Shielding Reactor, an unshielded reactor that was hung 200' in the air dangling between 310' steel towers. While the program successfully demonstrated several of the concepts (including a
nuclear-powered gas turbine engine running in Idaho, and a modified B-36 that carried a nuclear reactor but wasn't propelled by it (mentioned above), the program was canceled in 1961 due to feasibility and budget concerns.

Austrian research company IAT21 has presented a new type of aircraft at the Paris Air Show which has the potential to become aviation's first disruptive technology since the jet engine. ... The key to the D-Dalus' extreme maneuverability is the facility to alter the angle of the blades (using servos) to vector the forces, meaning that the thrust can be delivered in your choice of 360 degrees around any of the three axes. Hence D-Dalus can launch vertically, hover perfectly still and move in any direction, and that's just the start of the story.

The largest model railway layout in the world, Hamburg's
Miniatur Wunderland has been featured here
before. Featuring areas modelled on real life attractions, it also is home to the fictional town of
Knuffingen where the 200,000 mini-inhabitants are very much looking forward to the opening of their new
airport.

21st Century Jet: The Building of the 777 (part 1 of 5) In the early 90's, Boeing decided to build a new airplane, the 777. They also decided to allow KCTS Television and Channel Four London to film the design, construction, and testing of the new airliner. This 5-hour documentary, first aired in 1996, is no longer shown on TV, and out of print on VHS, but you can now watch it on Google Videos.

A Zimbabwean cargo aircraft
crashed earlier today at Shanghai-Pudong airport, killing three and seriously injuring four. It is not yet known why the aircraft, an ex Varig MD-11F (
pic) operated by an airline called Avient, failed to become airborne, but the airline itself has received quite some attention recently. Headquartered in Salisbury, Wiltshire, United Kingdom, they almost went bankrupt, leaving behind massive debts in France, only to almost out of nowhere get this MD-11F, which
crashed within a week of being acquired. (
pprune, reg req) But that's not the only shady thing about this airline...

Building and flying free flight model airplanes is a pastime so obscure it doesn't even register on the geek heirarchy. But in the period between Lindberg's flight across the Atlantic until the start of the Second World War,
thousands of boys (and some girls)
around the
world succumbed to the allure of rubber,
lube, and
dope.

Flawless Aircraft Emergency Landings (QLYTP). Breatheless reporting aside, it looks like when a pilot can control the landing, these aircraft are tough enough that no one need be hurt. Many more excellent videos in the post-video links, too.

I love nicely done home-built aircraft. I discovered
Mark Langford's website over a year ago but forgot to bookmark it. Thankfully, I recently found it again.
His dedication (obsession?) is obvious. I can't get over how many parts he custom built for his plane. He suffered an engine failure in his Corvair engine at one point, and I loved how he took the engine apart afterward and gave a full rundown about what happened.
