X-51A Waverider flight test postponed Published March 24, 2011 WRIGHT-PATTERSON AIR FORCE BASE, Ohio -- The Air Force elected not to launch the X-51A Waverider during a planned March 24 hypersonic flight test at Edwards Air Force Base, Calif. An Air Force Flight Test Center B-52 bomber departed Edwards AFB carrying the X-51A shortly before 9 a.m. Pacific Time and flew as planned to the designated launch area over the Navy Point Mugu Sea Range, however test controllers opted to not initiate the test since all required test conditions could not be met. The next flight test attempt will be rescheduled following a check of the system and when range and test assets can again be aligned.
