A replica of the NASA's AD-1 The NASA AD-1 was both an aircraft and an associated flight test program conducted between 1979 and 1982 at the NASA Dryden Flight Research Center, Edwards California, which successfully demonstrated an aircraftwing that could be pivoted obliquely from zero to 60 degrees during flight.The unique oblique wing was demonstrated on a small, subsonic jet-powered research aircraft called the AD-1 (Ames-Dryden-1). The aircraft was flown 79 times during the research program, which evaluated the basic pivot-wing concept and gathered information on handling qualities and aerodynamics at various speeds and degrees of pivot. Control:Classic flight control VTOL to swing the wing.Enjoy!!
