60 years later: still the fastest man on earth
On December 10, 1954, Col. John P. Stapp propelled down the Holloman High Speed Test Track aboard the Sonic Wind Rocket Sled 1 at a rate of 632 miles per hour, earning the title "The Fastest Man on Earth." Stapp’s experiment was the last human test at the HHSTT. His findings proved a pilot flying at 35,000 feet, going twice the speed of sound, could withstand the wind blast if he or she had to eject.
