Kites have been around for thousands of years and they are a part of many different cultures around the world. From an aerodynamics point of view, two of the most important users of kites were the Wright brothers. In 1899, as they were developing their theories for the control of an aircraft by using wing warping, they built a small maneuverable kite to verify their ideas. Between 1900 and 1903 they would often fly their gliders as unmanned kites at Kitty Hawk, North Carolina. These experiments led directly to their successful 1903 aircraft.
