The ring wing or annular airfoil is an aircraft design which has been experimented with throughout the history of aviation with some interesting variations. It has served as the inspiration for several paper airplane designs, model airplanes of course, and a variety of children's toys. The capabilities imagined by the French coléoptère engineers of the 1950's and 1960's and the U.S. "flying tank" designers are available today at least in the form of unmanned vehicles (large PDF brochure, 6 minute video download, 1½ minute YT news clip). The technology has also been adapted to become the surfboard tunnel fin and there are underwater UAVs as well.

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.

Planes check in but they don’t check out. At boneyards across the country, derelict airliners await cannibalization, destruction, or possible restoration.

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."
