The North American X-15 rocket-powered research aircraft bridged the gap between piloted flight within the atmosphere and piloted flight beyond the atmosphere into space. After completing its initial test flights in 1959, the X-15 became the first winged aircraft to attain velocities of Mach 4, 5, and 6 (four, five, and six times the speed of sound).

The program was a joint U.S. Air Force/Navy/NASA project, and four of its 12 pilots were U.S. Air Force officers. One pilot, USAF Maj. Michael J. Adams, died in an X-15 crash in 1967. Another X-15 pilot, Neil Armstrong, later became the first man to walk on the moon. #dronevideo #x15 | National Museum of the U.S. Air Force | Facebook
