Research Project X-15 1962

Overview

The X-15 was the last in a line of manned rocket-powered research airplanes built during the 1950s to explore ever-faster and higher flight regimes. Nineteen years before Space Shuttle, the X-15 showed it was possible to fly into, and out of, space. Launched from the wing of a modified B-52 bomber, the ship rocketed higher and faster than any manned aircraft of the time. There had never been anything like the X-15; it had a million-horsepower engine and could fly twice as fast as a rifle bullet.
