The Blue Flame was the high-performing, ultra high-speed, rocket-powered vehicle which achieved the world land speed record on Bonneville Salt Flats in Utah on October 28, 1970. The Blue Flame was constructed in Milwaukee, Wisconsin by Reaction Dynamics, a company formed by Pete Farnsworth, Ray Dausman and Dick Keller who had developed hydrogen peroxide rocket dragsters. The Blue Flame used a combination of hydrogen peroxide and liquified natural gas (LNG), pressurized by helium gas to eclipse previous speed records set with jet engine powered vehicles. LNG was used in the actual record-setting performance but at a lower ratio of LNG to the hydrogen peroxide oxidizer than would be used at maximum design thrust. This was the original plan for the record runs in 1970. The effort was sponsored by The American Gas Association, with technical assistance from the Institute of Gas Technology of Des Plaines, IL. The Blue Flame's record 1014.656 km/h (630.478 mi/hr) lasted for 13 years and was set as an average of achieved speed in both ways ((629.412 + 631.367)/2= 630.478 mi/hr). The driver, Gary Gabelich, was of Croatian ancestry and native of San Pedro, California.
