In the mid 1970s, NASA developed the Oblique Wing Research Aircraft (OWRA), a small remotely piloted aircraft to investigate the aerodynamics and flight characteristics of oblique wings. Its novel asymmetrical wing can pivot between 60 and 90 degrees around a central point on the fuselage.

The subsonic, propeller-driven, proof-of-concept OWRA was built as a first step to test NASA aerodynamicist Robert T. Jones’ theory that a supersonic transport with an oblique wing would have twice the fuel efficiency of a conventional supersonic airliner. Test results encouraged NASA to build the AD-1, a manned oblique wing aircraft that confirmed the design’s low speed flight characteristics.
