On 16-Aug-1960, Captain Joseph Kittinger of the US Air Force parachuted from a helium balloon at an altitude of 102,800 ft (19.5 miles / 31,354m) setting three world records; the highest parachute jump, the longest free fall (85,300 ft in 4 mins 36 seconds) and the first person to break the speed of sound without an aircraft (714 mph).
He broke skydiving records for exit altitude, vertical freefall distance without drogue, and vertical speed without drogue. Though he still holds the latter records, the first was broken two years later, when on 24 October 2014, Alan Eustace jumped from 135,890 feet - or, 41.42 km (25.74 mi) with a drogue.
