In this picture from August 14, an X-48B prototype is flying over Rogers Dry Lake at Edwards Air Force Base in California, in its fifth trip aloft since its debut flight in mid-July. Following a sixth flight not long ago, the aircraft is now on hiatus till sometime in October as Boeing--and partners NASA and the U.S. Air Force Research Laboratory--perform maintenance, update software and flight control systems, and evaluate data from the first round of flights. Among the physical changes under way: engineers are taking off removable leading edges with extended slats and replacing them with slatless leading edges, NASA said.
