The X-15 was a rocket plane that operated at the edge of space. The programme lasted from 1959 until 1968 and during that period 8 of its 12 pilots achieved astronaut status. These were White, Rushworth, Engle, Knight, Dana, Walker, Adams, and McKay (the others were Crossfield, Thompson, Petersen, and Armstrong).
