D-558-2 Skyrocket

"The Douglas Skyrocket (D-558-2) was a rocket and jet-powered research aircraft built by the Douglas Aircraft Company for the United States Navy. On November 20, 1953, shortly before the 50th anniversary of powered flight, Scott Crossfield piloted the D-558-2 to Mach 2, the first time an aircraft had exceeded twice the speed of sound. Since it was so fast, it would sometimes be used to fly over enemy territories and take pictures. A total of three Skyrockets had been built, and all are now on display in different locations. "
