This 35 second video clip shows D-558-1 Skystreak full power engine runs and taxi tests at Muroc Army Airfield.

With assembly complete and its systems checked out, the first Skystreak was ready for its first flight. This was flown by Douglas test pilot Gene May. In 1947, May was 42 years old, a grandfather, and had been flying for Douglas Aircraft Co. for some six years. This footage was from a Douglas documentary film.
