Are there any flying Wings left?
Unfortunately, the short answer is “no.” The U.S. Air Force reports that all of the XB-35s and the YB-49s were scrapped by 1953; Northrop’s beautiful flying wings today exist only in reports and photographs.
Who had the first flying wing?
Possibly the first true flying wing, which was shaped like an elliptical seed, was designed and flown by Czechoslovakian designer Igo Etrich in 1909. He abandoned the true wing concept and added a tail for stability.

What were paper airplanes used for?
During the early 1900s Aero magazines published several articles using paper airplane models to demonstrate aerodynamic principles. The Wright brothers reportedly use paper planes, wings and airfoils in wind tunnels as part of their quest to build the first powered human carrying airplane.
What kind of plane was in Raiders of the Lost Ark?
BV-38
The BV-38 is a fictitious aircraft, albeit one that Raiders production designer Norman Reynolds extrapolated from a number of real designs, most notably the Horten Ho 229, a jet wing test-flown by the Luftwaffe in 1943.
Why are flying wings unstable?
A pure flying wing is theoretically the lowest drag design configuration for a fixed wing aircraft. However, because it lacks conventional stabilizing surfaces and the associated control surfaces, in its purest form the flying wing suffers from being unstable and difficult to control.
What name has a blue code?
Lockheed Have Blue
Lockheed Have Blue was the code name for Lockheed’s proof of concept demonstrator for a stealth bomber. Have Blue was designed by Lockheed’s Skunk Works division, and tested at Groom Lake, Nevada.
What was Project Harvey?
The story of Have Blue begins with a DARPA effort called Project Harvey—named for the invisible six-foot-three-and-a-half-inch rabbit from the play and film of the same name. The future of integrated air defense systems had already proved effective in the last years of the Vietnam War.
What is The wingspan of a YB-49 bomber?
The YB-49 and its modern counterpart, the B-2 Spirit, both built either by Northrop or Northrop Grumman, have the same wingspan: 172.0 ft (52.4 m). Flight test data collected from the original YB-49 test flights were used in the development of the B-2 bomber.
How many YB-49s were actually built?
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 piston-driven design.
What is a Northrop YB-49?
The YB-49 featured a flying wing design and was a turbojet -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 piston-driven design.
What year did the first YB-49 fly?
The first of these new YB-49 jet-powered aircraft flew on 22 October 1947 (from Northrop airfield in Hawthorne, CA) and immediately proved more promising than its piston engined counterpart. The YB-49 set an unofficial endurance record of staying continually above 40,000 ft (12,200 m) for 6.5 hours.
