That day the supersonic speed was developed at the Edwards US Airforce Base in California. Stan Barret, an American racer, was steering a three-wheel Budweiser rocket. The name was not fake as the car was really equipped with a rocket engine. This combination of the car and the rocket allowed Stan to drive along the crow line at the speed of 1190.377 km/h, which is 1.0106 times higher than the speed of sound. It is a pity that the record was not recognized as official because the radar had not been certified.
