NASA took a major step toward redefining high-speed flight on Nov. 16, 2004. The X-43A, a small, experimental aircraft, proved that an engine drawing oxygen from the atmosphere could propel an aircraft to hypersonic speeds – greater than Mach 5, or five times the speed of sound. During the flight over the Pacific Ocean west of California, the X-43A set the world speed record for a jet-powered aircraft, reaching Mach 9.6, or nearly 7,000 mph. The mission originated from NASA’s Armstrong Flight Re

The X-15 experimental aircraft achieved its first hypersonic flight on June 23, 1961, soaring at speeds over five times the speed of sound. Later, the X-43A reached about 7,000 mph using innovative engines that harnessed atmospheric oxygen. For nearly eight decades, NASA Armstrong has been at the forefront of high-speed research, achieving these and many other milestones. Today, our engineers are developing technologies to make space access safer and more affordable, and to bring routine commerc

Boeing and Defence Science Technology group in Australia are making hypersonics happen with a recent flight test of an experimental hypersonic vehicle. The flight test was a success and brings us a step closer to hypersonic aircraft. | The Boeing Company
