This rare promotional film discusses the merits of the Northrop YB-49 Flying Wing. This unique aircraft was a prototype jet-powered heavy bomber aircraft developed by Northrop shortly after World War II. Intended for service with the U.S. Air Force, the YB-49 featured a flying wing design. It was a jet-powered development of the earlier, piston-engined Northrop XB-35 and YB-35; the two YB-49s actually built were both converted YB-35 test aircraft. The YB-49 never entered production, being passed over in favor of the more conventional Convair B-36 Peacemaker piston-driven design. Two completed prototype aircraft were lost in accidents (one of them fatal for the pilot and crew), and the remaining airframes were destroyed on the order of the Secretary of the Air Force after the program was cancelled. Design work performed in the development of the YB-35 and YB-49 nonetheless proved to be valuable to Northrop decades later in the eventual development of the B-2 stealth bomber, which entered service in the early 1990s.
