NASA's predecessor, NACA, operated the Douglas Skyrocket.
A successor to the Air Force's Bell X-1, the D-558-II could operate under rocket or jet power.
It conducted extensive tests into aircraft stability in the transsonic range, optimal supersonic wing configurations, rocket plume effects, and high-speed flight dynamics.
On November 20, 1953, the Douglas Skyrocket became the first aircraft to fly at over twice the speed of sound when it attained a speed of Mach 2.005.
Like the X-1, the D-558-II could be air-launched using a B-29 Superfortress.
Unlike the X-1, the Skyrocket could also takeoff from a runway with the help of JATO units.
