-------------------------------------------------------------------------------- EDWARDS AFB - NASA Dryden Flight Research Center is preparing to flight test a prototype blended wing body aircraft as part of a joint program with the Air Force Research Laboratory and The Boeing Co. This unusually-shaped aircraft design - described as a cross between a conventional aircraft and a flying wing - is believed to offer greater fuel efficiency by providing more lift and better aerodynamics. The aircraft is shaped as an elongated triangle, with a smooth line from the fuselage extending out into the wings. The Air Force is interested in the technology, should it prove viable,...
