Sir Barnes WallisBorn 26 Sep 1887; died 30 Oct 1979 at age 92. Sir Barnes Neville Wallis was an English aircraft designer and military engineer whose famous 9000-lb bouncing “dambuster” bombs of WW II destroyed the German Möhne and Eder dams on 16 May 1943. He designed the R100 airship, and the Vickers Wellesley and Wellington bombers. The specially-formed RAF 617 Squadron precisely delivered his innovative cylindrical bombs which were released from low altitude, rotating backwards at high speed that caused them to skip along the surface of the water, right up to the base of the dam. He later designed the 5-ton Tallboy and 10-ton Grand Slam earthquake bombs (which used on many enemy targets in the later years of the war). Postwar, he developed ideas for swing-wing aircraft.«[Image: Wallis at his drawing board.] |
