On December 21, 1979, the National Aeronautics and Space Administration (NASA) AD-1 Oblique Wing Research Aircraft (OWRA) took off from the main runway at Edwards Air Force Base (AFB), CA, for a 45-minute checkout flight. It marked the worlds first flight of a piloted oblique-wing airplane. This historic flight, which was flown with the airplanes wing at its straight (0-degree angle) position, was soon followed by flights at wing angles of 15 degrees, 20 degrees, 45 degrees, and finally on April 24, 1981, at the 60-degree-angle design goal, thus proving the aerodynamic concept of an airplane with an oblique-wing configuration. This initial oblique-wing program, which ran from 1976 through 1982, was a joint effort between NASAs Ames Research Center and Dryden Flight Research Center, CA, thus giving rise to the aircrafts nameAmes-Dryden AD-1 Oblique Wing Research Aircraft. Extensive research, wind tunnel and computer-code testing, and model-building and testing projects were undertaken at Ames, and flight simulation, flight testing, and flight evalu-ation were conducted at Dryden. While the concept of the oblique wing was developed during World War II, and the landmark wind tunnel tests of John P. Campbell and Hubert M. Drake were undertaken just follow-ing the end of the war, most aeronautical attention in the postwar era concentrated on the continuous refinement of symmetrical point-forward swept-wing aircraft.
