U.S. aiming to hit 6,000 km/h in test flight of supersonic ‘waverider’
The U.S. military conducted an unmanned test flight on Tuesday of its hypersonic Waverider aircraft, designed to move at six times the speed of sound using technology that bridges the gap between planes and rocketships, a military official said.
A B-52 bomber launched the remotely monitored, nearly wingless experimental aircraft, officially known as the X-51A, between 10 a.m. and 11 a.m., John Haire, a spokesman for the 412th test wing at Edwards Air Force Base in California, said in a statement. Results of the brief test flight will be released on Wednesday, he said. (US Air Force / AFP/Getty Images)
