At the 1968 Summer Olympics Bob Beamon jumped 8.90 m (29 ft 2 1â4 in) at an altitude of 7,349 feet (2,240 m), a jump not exceeded for 23 years, and which remains the second longest legal jump of all time.
This spectacular multi-angle video shows Guerlain Chicherit's attempt to beat the world record for the longest car jump, which is now held by Tanner Foust at 332 feet (101 meters). Chicherit tried save a 360 feet (109.7 meter) gap between a 20-ton steel ramp and a concrete landing surface. Fortunately, he didn't die.
