Felix Baumgartner

On 14 October 2012 Austrian skydiver Felix Baumgartner stepped out of a helium balloon capsule about 39 km above New Mexico and fell at a top speed of 1,357.6 km/h (843.6 mph, Mach 1.25). He became the first person to break the speed of sound without a vehicle.

The first figure released was lower. It was revised upward after Guinness reviewed the data. A higher jump by Alan Eustace in 2014 did not reach this speed.
