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.

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.

Eject! Eject! Eject! Whether used in the
air, on
land, at
sea (and
under it), or
on the way to the Moon,
ejection seats and
capsules have saved
thousands of aviators
worldwide. The
basic concept was first tested in
1912, developed by the
Germans in WWII, and became standard safety equipment in
high-speed,
high-altitude jet and rocket aircraft. (Although
ejection seats were in
Gemini spacecraft, they were only in early
Space Shuttle flights.) Much happens very quickly
during ejection, and harrowing
accidents and pilot
deaths still occur. The decision not to eject right away may be heroic, but even pilots who wait may live while
innocent bystanders^ die. However, the efforts of
dedicated researchers and
rocket sled testing by seat
manufacturers keep adding
new members to the unique
club of men and women who survive to fly again.

X-43A Flight. "The unpiloted 12-foot-long X-43A vehicle, part aircraft and part spacecraft, will be dropped from the wing of a B-52 aircraft, lofted to nearly 100,000 feet by a booster rocket and released over the Pacific Ocean to briefly fly under its own power at seven times the speed of sound."
