Engineers have installed a small-scale blended wing body prototype in an historic wind tunnel that once hosted some of America's greatest aviation pioneers, including Orville Wright, Howard Hughes and Charles Lindbergh. Designated the X-48B by the U.S. Air Force, the prototype was developed by Boeing Phantom Works. It is being tested in the Full-Scale Tunnel at NASA's Langley Research Center in Hampton, Va.
