Ames-Dryden (AD)-1 Oblique Wing
The NASA AD-1 was an aircraft and a flight test program conducted between 1979 and 1982 at the NASA Dryden Flight Research Center in Edwards California. Its first flight was in December 1979, and it retired in August 1982. For some reason, this feels like one of those toys where you would wind it up and then it would work for a few seconds. Except…it’s actually a functional aircraft.
