X-15 aircraft in flight and landing, 1960s. Footage from a chase aircraft of an X-15 test flight, followed by footage of the aircraft landing at Rogers Dry Lake, California, USA. The end of the clip shows the B-52 mothership flying over the landing site. The X-15 was a rocket-powered research aircraft designed to fly at hypersonic speeds. Manufactured by North American Aviation, it was operated by the United States Air Force (USAF) and the National Aeronautics and Space Administration (NASA). Three X-15s flew a total of 199 missions between 1959 and 1968. The X-15 was carried into the air by one of two converted B-52 bombers and released at high altitude. The pilot then ignited the X-15's rocket motor for a flight lasting around 10 minutes. It was the first plane to reach the edge of outer space (the highest altitude attained was 107 kilometres), and set records for the fastest manned aircraft (7, 274 kilometres per hour, or Mach 6.72). The B-52 motherships took off from nearby Edwards Air Force Base. |
