Bell X-5 Swing Wing

The X-5 was tested from 1951 until 1955 at the NACA High-Speed Research Station. Built by Bell Aircraft Company, the X-5's maiden flight was June 20, 1951. The X-5 was the first aircraft capable of sweeping its wings in flight and helped our understanding of wing-sweep angles of 20, 45, and 60 degrees at subsonic and transonic speeds. X-5 Ship #1 (50-1838) was flown by NACA from 1952 to late 1955. X-5 Ship #2 (50-1839) was operated only by Bell and the Air Force and was lost in a spin accident in 1953.
