The X-15 is the fastest aircraft ever made. Music: Blood Moon by Dhruva Aliman - https://dhruvaaliman.bandcamp.com/album/what-must-be ...http://www.dhruvaaliman.com/ ...After initial test flights in 1959, X-15s became the first aircraft to reach Mach 4, 5, and 6, and to operate well above 30,500 meters (100,000 feet). On October 3, 1967, pilot William J. "Pete" Knight flew the X-15 on its fastest flight reaching 4,519 mph (7,273 km/h). Among the 12 pilots who flew the X-15 were future Apollo 11 commander Neil Armstrong and Space Shuttle astronaut Joe Engle.
The X-15 gathered critical flight data that made human spaceflight and future hypersonic aircraft possible. The North American X-15 rocket-powered research aircraft bridged the gap between manned flight within the atmosphere and manned 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). Because of its high-speed capability, the X-15 had to be designed to withstand aerodynamic temperatures on the order of 1,200 degrees F.; as a result, the aircraft was fabricated using a special high-strength nickel alloy named Inconel X.
Air-launched from a modified Boeing B-52 Stratofortress aircraft, the X-15 required conventional aerodynamic control surfaces to operate within the atmosphere and special "thruster" reaction control rockets located in the nose and wings of the aircraft to enable the pilot to maintain control when flying on the fringes of space. Indeed, the X-15 design was so much like that of a space vehicle that during the formative days of Project Mercury, America’s first attempt to put a man in orbit, North American and National Air and Space Administration (NASA) engineers gave serious consideration to utilizing a growth version of the X-15 for the manned orbiting mission. This plan was dropped in favor of using a blunt-body reentry vehicle. Because of the potential dangers to the pilot should the X-15’s pressurized cockpit lose its atmosphere while the aircraft operated in a near-space environment, X-15 pilots wore specially developed full-pressure protection ‘spacesuits’ while flying the experimental plane.
Three X-15 research aircraft were built and flown, completing a total of 199 research flights. The National Air and Space Museum has the historic X-15 #1, Air Force serial 56-6670. The X15 #2 (56-6671) was rebuilt following a landing accident as the advanced X-15A-2, having increased propellant capacity and, hence, a higher potential performance. The X-15A-2 was the fastest X-15 flown, and it is now on exhibit at the Air Force Museum, Wright-Patterson Air Force Base, Ohio. The X-15 #3 (56-6672) featured an advanced cockpit display panel and a special adaptive control system.
