Early glider. Wilbur Wright, one of the famous Wright brothers, flying a glider in 1902. It was by using gliders such as these that the Wright brothers discovered that the accepted aerodynamic data on which they relied was incorrect. The Wright brothers tested the effects of air pressure on more than 200 wing surfaces. This research allowed them to make the first ever powered flight at Kitty Hawk, North Carolina, USA, in 1903.
