The North American X-15 is a hypersonic rocket-powered aircraft which was operated by the United States Air Force and the National Aeronautics and Space Administration (NASA) as part of the X-plane series of experimental aircraft.

The X-15 and other X-planes are more than a historical legacy for NASA. The program is the core of NASA’s New Aviation Horizons, an array of new experimental aircraft that will carry on the legacy of demonstrating advanced technologies to push back the frontiers of aviation.

Feb 28, 2014 · Manufactured by North American Aviation Inc., three rocket-powered X-15s flew a total of 199 times, with North American (and former National Advisory Committee for Aeronautics or NACA) pilot Scott Crossfield making the first, unpowered glide flight on June 8, 1959.

Sep 17, 2024 · The X-15 hypersonic rocket-powered aircraft, built by North American Aviation (NAA), greatly expanded our knowledge of flight at speeds exceeding Mach 6 and altitudes above 250,000 feet. A joint project among NASA, the U.S. Air Force, and the U.S. Navy, the X-15’s first powered flight took place on Sept. 17, 1959, at the Flight Research ...

Still the fastest airplane ever flown, the North American X-15 earned its title 40 years ago, when on October 3, 1967 Air Force Major William “Pete” Knight flew the rocket-powered aircraft to...

Jan 7, 2025 · X-15, rocket-powered research aircraft built in the 1950s by North American Aviation, Inc., for the U.S. military and the National Aeronautics and Space Administration in order to gather information on flight conditions beyond the atmosphere.

As the X-15 plummeted into the increasingly thicker atmosphere, the Honeywell adaptive flight control system caused the vehicle to begin oscillating.

First flown in 1959, the North American X-15 bridged the gap between human flight in the atmosphere and spaceflight. It was the first winged aircraft to fly Mach 4, 5, & 6 and to operate at altitudes above 30,500 m (100,000 ft). Eight of 12 pilots received astronaut wings.

Aug 14, 2022 · Known as the fastest manned rocket aircraft ever flown, the North American X-15 is an engineering marvel. It made the first manned flights to the edge of outer space and was the first aircraft to reach hypersonic speeds – that’s over five times the speed of sound.

Aug 28, 2010 · The X-15 remains the fastest and highest flying manned aircraft ever flown, and is regarded by many as the most important research plane in history. The X-15 emerged from a combined US Air Force and US Navy request for a research aircraft to reach altitudes of 250,000 ft and speeds exceeding Mach 6.
