6. Highest jump As jets began to fly higher and faster, the military became concerned about saving pilots in the case of high-altitude disaster.
To find out what the human body was capable of, Capt. Joseph W. Kittinger Jr. jumped three times from dizzying heights: once from 76,400 feet, once from 74,700 feet, and finally, on Aug. 16, 1960, from 102,800 feet (23,287 m, 22,769 m and 31,333 m, respectively).
That last jump still holds the record for highest and fastest human fall Kittinger fell freely for 84,700 feet (25,817 m), reaching a speed of 614 miles per hour (988 km per hour).
Thirteen minutes and 45 seconds after he stepped from his balloon-supported gondola, Kittinger was safely on the ground in Tularosa, N.M.
"It was definitely beautiful, but it's also hostile," Kittinger told The New York Times in 2008, recounting how his right hand swelled up to twice its normal size during the jump because his pressurized glove did not work properly.
