In this July 17, 2009 photo provided by the U.S. Air Force, an X-51A WaveRider hypersonic flight test vehicle is uploaded to an Air Force Flight Test Center B-52 for fit testing at Edwards Air Force Base. Four scramjet-powered Waveriders were built for the Air Force. The Los Angeles Times says the unmanned X-51 WaveRider is expected to reach Mach 6 _ or about 3,600 mph _ Tuesday, Aug. 14, 2012, when it's dropped by a B-52 bomber and takes flight off the Southern California coast near Point Mugu.
