Dr. Woldemar Voigt designed the Me 262 and P.1101 jet aircraft at Messerschmidt. Before the war's end he had redesigned the Me 262 by placing the turbines in the wing roots. Voigt's Me P.1107/B, heavy bomber design was used in the almost identical design of the British Vickers "Valiant" Mk. 1 bomber in 1950. In 1946 he came to the US under "Operation Paperclip" and worked for Bell Aircraft on the X-5 and other aircraft.
