The Douglas D-558-2 "Skyrockets" were among the early transonic research airplanes like the X-1, X-4, X-5, and X-92A. Three of the single-seat, swept-wing aircraft flew from 1948 to 1956 in a joint program involving the National Advisory Committee for Aeronautics (NACA), with its flight research done at the NACA's Muroc Flight Test Unit in Calif., redesignated in 1949 the High-Speed Flight Research Station (HSFRS); the Navy-Marine Corps; and the Douglas Aircraft Co.
The HSFRS became the High-Speed Flight Station in 1954 and is now known as the NASA Dryden Flight Research Center. The Skyrocket made aviation history when it became the first airplane to fly twice the speed of sound.
On Nov. 20, 1953, shortly before the 50th anniversary of powered flight, Crossfield piloted the Douglas D-558-2 Skyrocket research aircraft to Mach 2 - twice the speed of sound, or more than 1,290 mph (Dryden Flight Research Center, NASA).
