USAF vehicle breaks record for hypersonic flight
Thursday, May 27, 2010; 6:21 AM
WASHINGTON -- An experimental aircraft has set a record for hypersonic flight, flying more than 3 minutes at Mach 6 - six times the speed of sound.
The X-51A Waverider was released from a B-52 Stratofortress off the southern California coast Wednesday morning, the Air Force reported on its website. Its scramjet engine accelerated the vehicle to Mach 6, and it flew autonomously for 200 seconds before losing acceleration. At that point the test was terminated.
The Air Force said the previous record for a hypersonic scramjet burn was 12 seconds.

NASA developing hypersonic technologies; flight vehicles only decades away

NASA will develop, test and fly the Hyper-X series over the next two decades to support development of future-generation reusable launch vehicles and improved access to space.
