On 16 August 1960, Kittinger jumped from a balloon high in the stratosphere to make the longest skydive from the highest altitude in history. It is a common misconception that Kittinger exceeded the speed of sound during his fall, but this was not the case. He did reach a peak velocity of 614 mph (988 km/h), however, a mark that still stands as the fastest speed ever reached by a human without a vehicle. Though Kittinger fell short of supersonic speeds, he did get pretty close and achieved a maximum of about Mach 0.9, or 90% of the speed of sound. Joseph Kittinger
