Northrop XB-35 "Flying Wing" - The Northrop XB-35 and YB-35 were experimental heavy bomber aircraft developed for the United States Army Air Forces during and shortly after World War II by the Northrop Corporation. It used the radical and potentially very efficient flying wing design, in which the tail section and fuselage are eliminated and all payload is carried in a thick wing.
The Horten Ho-229 flying wing fighter, first flown in 1944 by the Luftwaffe, rebuilt to exact specs by the model testing team at Northrop Grumman. The German prototype fighter/bomber designed by Reimar and Walter Horten and built by Gothaer Waggonfabrik late in World War II. It was the first pure flying wing powered by jet engines. Since the appearance of the B-2 Spirit flying wing stealth bomber in the 1990s, some describe the Ho 229 as "the first stealth bomber".
