The Wright brothers designed, built and flew a series of three manned gliders in 1900–1902 as they worked towards achieving powered flight. They also made preliminary tests with a kite in 1899. In 1911 Orville conducted tests with a much more sophisticated glider. Neither the kite nor any of the gliders was preserved, but replicas of all have been built.
The 1899 kite, which Wilbur flew near his home in Dayton, Ohio had a wingspan of only 5 feet (1.5 m). This pine wood and shellacked craft, although too small to carry a pilot, tested the concept of wing-warping for roll control that would prove essential to the brothers' solving the problem of controlled flight. The Wrights burned the craft along with other trash in 1905.
The 1900 Wright Glider was the brothers' first to be capable of carrying a human. Its overall structure was based on Octave Chanute's two-surface glider of 1896. Its wing airfoil was derived from Otto Lilienthal's published tables of aerodynamic lift. The glider was designed with wing-warping capability for full-size testing of the concept first tried on the 1899 Wright Kite.
The glider was first flown as an unmanned kite on October 5, 1900 near Kitty Hawk, North Carolina. Next, Wilbur rode as pilot while men on the ground held tether ropes attached to the airborne craft. Subsequently, Wilbur made about a dozen free flights on a single day, concluding the season's test efforts. The brothers abandoned the glider when they broke camp on 23 October, and it eventually disappeared in the region's severe storms. The fabric covering of the wing components were given to the wife of helper Bill Tate, whose family Wilbur first stayed with at Kitty Hawk in 1900. Mrs. Tate allegedly used the material to make dresses for her daughters.
The 1901 Wright Glider was the second of the brothers' experimental gliders. They tested it over the Kill Devil Hills, four miles south of Kitty Hawk. The glider was similar to the 1900 version, but had larger wings. It first flew on July 27, 1901, and was retired on August 17. During this time it made between 50 and 100 free flights, in addition to tethered flights as a kite.
