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 191

Wing warping was an early system for lateral control of a fixed-wing aircraft or kite. The technique, used and patented by the Wright brothers, consisted of a system of pulleys and cables to twist the

…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…
