After the war, Welch became the chief test pilot for [[North American Aviation]] and flew the first prototypes of the F-86 Sabre. On one of these flights, Welch actually broke the sound barrier (before Yeager’s famous flight) while in a dive. He later test-flew the [[F-100 Super Sabre]]. George Welch was killed during a demonstration flight in 1954 when his Super Sabre crashed due to a design flaw.<ref>[http://www.aerospaceweb.org/question/history/q0113.shtml First Supersonic Jet]</ref> | After the war, Welch became the chief test pilot for [[North American Aviation]] and flew the first prototypes of the F-86 Sabre.
