http://en.wikipedia.org/wiki/Wingsuit_flying (much older sport than I ever realized)
Wings were first used in the 1930s as an attempt to increase horizontal movement. These early wingsuits were made of materials such as canvas, wood, silk, steel, and even whale bone. They were not very reliable. According to wingsuit lore, between 1930 and 1961, 72 of the 75 original birdmen died testing their wingsuits[citation needed]. Some "birdmen", notably Clem Sohn and Leo Valentin, claimed to have glided for miles.
The wingsuit was showcased in the 1969 movie The Gypsy Moths starring Burt Lancaster and Gene Hackman.
In the mid-1990s, French skydiver Patrick de Gayardon developed a wingsuit that had unparalleled safety and performance.[citation needed] De Gayardon died on April 13, 1998 while testing a new modification to his parachute container in Hawaii; his death is attributed to a rigging error which was part of the new modification rather than a flaw in the suit's design.
In early 1998, Tom Begic, a BASE jumper from Australia, built and flew his own wingsuit based on a photograph of Patrick de Gayardon and his ideas. The suit was developed to assist Begic in capturing freefall footage of BASE jumpers while jumping the high cliffs of Europe. The benefits of the suit included reduced freefall descent rates, increased freefall times, greater maneuverability around other jumpers and objects whilst in freefall, the potential to jump off sites around the world that were not possible without wingsuits, and the ability to accelerate away from underhung walls much more quickly. In early 1999, Begic stopped development of his suit when he met Robert Pečnik and learned of plans for the creation of a wingsuit manufacturing company. Phoenix Fly was started in the mid 2000s.
