Hang gliding is a recreational activity and competitive sport closely related to gliding, but using much more minimalistic craft often consisting of a metal-framed fabric wing, with the pilot mounted on a harness hanging from the wing frame and exercising control by shifting body weight against a triangular bar also attached to the frame.
Many early experiments with gliding flight throughout the late 19th century were performed using craft that would now be considered hang gliders, and interest in the sport continued throughout the 20th century.
Hang gliding was invented, or at least strongly influenced, by the NASA technician Francis Rogallo in the 1960s who had to develop a landing system for the Apollo astronauts return to earth. The major breakthrough was the famous flight of Mike Harker from the Zugspitze in Germany in 1972. After that hang gliding became popular all over the world, with the peak in the 1980s. After that it was superseded by paragliding. Today the relation is approximately 90:10.
In the '60s and the early '70s many gliders were built that can only be called "extremely dangerous". After that the development, know-how and materials were improved until the first glider came on the market that had all security elements that can still be found today: The "Atlas" (La Muette, 1978). Then performance increased rapidly. The first true "double surface" glider was the UP "Comet". The first glider without a keel pocket was the Wills Wing "HP" (~1990). In the late 1990s the kingpost on top of the wing was removed to further increase the performance by reducing drag. These gliders are now called "topless gliders". Both topless and kingposted gliders belong to the family of the "flex wings", because their sail is still a little flexible. This felxibility is required for the weightshift of the pilot to create small differences in the sail's tunnel, which in turn lets the glider fly to the right or to the left. In parallel the first commercially successful "rigid wing" came on the market (the "Exxtacy") with the leading edge completely made of carbon which avoids deformations at higher speed. The nose angle and wing span is a little higher, and the sail is rather stiff. This generation of gliders is controlled by spoilers typically on top of the wing, while the flex wings are still controlled by weight shift. In both flex- and rigid wings the pilot hangs below the wing without additional fairing except for the harness itself. A third class of hang gliders exists (officially called Sub-Class O-2 by the FAI) where the pilot is somehow integrated into the wing by means of a fairing. This offers the best performance and is most expensive. All types of gliders can be foot-started while landing of some class-2 gliders is only possible on wheels.
As a backup, pilots carry a parachute with them in the harness. In case of serious problems the parachute is deployed and carries both pilot and glider down to earth. The size is typically 30 m2 and the related sink rate should not exceed 6 to 7 m/s (can be less, depending on the state of the glider) which is still sufficient to break some bones.
Record fall into nearly the same categories as the ones of the sailplanes and are authorized by the FAI. Technically, the current world record (as of 2003) for "free distance" is held by Manfred Ruhmer with 700,6 km in 2001, but Mike Barber broke the world best with a distance of 704 km (437 miles) on June 19th 2002 in Texas.History
