Douglas D-558 Mk1 "Skystreak"

The United States Douglas Skystreak (D-558-1 or D-558-I) was a single-engine jet research aircraft of the 1940s. It was designed in 1945 by the Douglas Aircraft Company for the U.S. Navy Bureau of Aeronautics, in conjunction with the National Advisory Committee for Aeronautics (NACA). The Skystreaks were turbojet powered aircraft that took off from the ground under their own power and had unswept flying surfaces.
