Description
Acceleration and deceleration testing. Time-lapse images of John Stapp strapped in a sled seat during high G-force acceleration and deceleration testing. The images run from left to right, starting at upper left. The 27 rocket-propelled runs made by Lieutenant Colonel John Paul Stapp (born 1910) showed the effects of rapid accelerat- ion and deceleration on the human body. On December 10 1954, Stapp reached 632 miles per hour in 5 seconds before being brought back to rest in just over a second with a force of over 40 Gs. Despite initial blindness and collapsed lungs, he quickly recovered, proving that it was possible to survive an ejection from a supersonic aircraft.
