On this day in 1965, Lee Ann Roberts Breedlove, wife of land speed record-holder Craig Breedlove, became the first female driver to exceed 300mph when she sped to 308.50 mph in the Spirit of America - Sonic 1 vehicle over the Bonneville Salt Flats in Utah, USA. The Sonic 1 was a four-wheel vehicle powered by a J79 jet engine.
A few hours after Lee Ann jet-powered across the one-mile course, Craig Breedlove shattered his own record from the previous year when he reached 555.49mph in the Spirit of America.
