In 1902, the Wright Brothers conducted about one thousand glides with their newest glider, and increased their in-air distance to 622 1/2 feet for nearly 30 seconds.
1902 Technical Advancements
The Wright Brothers 1902 glider had a new movable rudder at the rear which was installed to improve yaw. The movable rudder was coordinated with the wing warping to keep the nose of the aircraft pointed into the curved flight path. This machine was the first aircraft in the world that had active controls for all three axis; roll, pitch and yaw.
