Spirit of America – Craig Breedlove

Craig Breedlove poses with his first world land speed record car, Spirit of America.

526.277 mph – Breedlove’s final Land Speed Record in Spirit of America, before progressing on to Spirit of America Sonic 1

468.719 mph – Breedlove’s previous speed record, set just 2 days before.

4,400 lbf – the amount of thrust generated by the General Electric J47 turbojet engine, measured in pound-force, a standardised value for acceleration (20 kN – kilonewtons).

$250,000 – the budget to build Spirit Of America (compared to just $78,000 to build competitor Wingfoot Express, or the $2,000,000 cost of Bluebird CN7).
