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.

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.

Legend has it that Charles Dellschau (1830-1923) was the draftsman for the secret Sonora Aero Club, a collective of 60 or so mostly German immigrants who reportedly constructed dirigible like aircraft in California in the 1850's. One club member was said to have discovered suppe -- the magic antigravity fuel alleged to have lifted the craft. There were sightings of these 'airships', tenuously linked back to the club, up to the end of the 20th century.
Dellschau, described variously as butcher, inventor, civil war spy, scientist and America's first visionary artist, retired at age 70 in Texas and spent the last 2 decades of his life as a recluse, producing mixed media art works that record the craft and workings of the fabled Sonora Aero Club. They are accompanied by cryptic symbols, newsprint about aircraft and detailed notebooks and were salvaged from the garbage in 1967. His artworks were selling for $15,000 each 5 years ago. A would-be author and long-time sleuth believes he has unlocked the mysteries of Dellschau's cryptic accoutrements and may be publishing a book on the legends this year. via

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

Pixelito and Proxflyer Micron, both at 6.9 grams, are thought to be the two smallest robotic flying micro-helicopters. These charming prototypes are the precursors of a surveillance technology that ranges from the hobbyist's draganflyer to DARPA's micromechanical flying insect. Learn more about how spy flies will work as we fly into the future.
