NASA's Dryden Flight Research Center in Edwards, Calif., provided critical support for the first flight July 20 of the X-48B. The 21-foot wingspan, 500-pound remotely piloted test vehicle took off for the first time at 8:42 a.m. PDT and climbed to an altitude of 7,500 feet before landing 31 minutes later. The Boeing Co. of Seattle developed the blended wing body research aircraft.
