Spy Handler writes "The Horton 229 Flying Wing, one of the more famous "Secret Weapons of the Luftwaffe" produced in the latter days of WWII, is noted for its striking similarity to the modern B-2 Stealth Bomber. The question remained, "How effective would it have been against Allied air defenses of the day?". Unfortunately no surviving example existed for testing... until now. Northrop Grumman, on its own time and money, built a replica using the original blueprints and conducted radar tests. The result? Very good for the Nazis, bad for Allied defenses trying to detect it.
National Geographic Channel will be airing a new documentary about this on Sunday July 5th. (Although Nat Geo calls it "Hitler's Stealth Fighter", the size and shape of the aircraft dictates that it wouldn't have been used for anything other than dropping bombs)"
