Why famous? The biplane aircraft, designed and built by the pioneering Wright brothers, is at the forefront of aviation history, performing the world’s first ever powered flight in 1903 over North Carolina, USA. It was built using giant spruce wood, with the engine and other parts all made by hand. A sprocket chain drive, borrowed from bicycle design, was used to power the twin propellers. To fly the plane, pilot Wilbur Wright lay on his stomach on the lower wing to reduce drag, with the steering controlled by with a hip cradle which pulled wires to warp the wings.
