1965 : Breedlove breaks 600 mph speed barrier
Craig Breedlove, driving his jet-powered Spirit of America--Sonic 1 vehicle, raced to 600.601 mph over the Bonneville Salt Flats in Utah, and set a new land-speed record. Breedlove, a four-time land-speed record holder, was also the first driver to break the 400 mph and 500 mph land-speed barriers, in 1963 and 1964 respectively. Five years later, Gary Gabelich, in his Blue Flame rocket-powered vehicle, would break Breedlove's record by reaching 622.407 mph over the Bonneville Salt Flats.
