Why did the Wrights control their first aircraft lying down?
The Wrights’ controls of 1900-1905 were essentially the same design: the pilot lay down on the lower wing, facing the front of the aircraft. With his left hand he controlled the elevator in front, and, with a hip cradle, used his body to warp the wings. The early gliders of 1900-1901 had foot controls for the warping, and the aircraft from 1902-1905 used a hip cradle. As with all aspects of their machines, the pilot’s position was a calculated part of their overall design. When designing the gliders, the Wrights estimated that the total drag of the glider would be one-half that of the machine with the pilot sitting upright. (Jakab, 75) Despite their success in controlled flight, their early supporter Octave Chanute expressed concern for their safety with this arrangement: “This is a magnificent showing, provided that you do not plow the ground with your noses”. The Wrights moved to sitting in 1908, and modified the controls first for that position, then for training. The U.S. Army cont
