John Stapp's rocket sled
A doctor hit 1,000 km/h and stopped in about a second

Air Force doctor John Stapp tested on himself how much deceleration a human can take. On 10 December 1954 a rocket sled took him to 1,017 km/h and stopped him in 1.4 seconds; he survived 46 g, and his work fed into car seat belts.

Murphy's law was born in John Stapp's tests. At Edwards Air Force Base in 1949 engineer Edward Murphy found every sensor wired backwards, and Stapp later repeated his grumble to the press: if anything can go wrong, it will. Share →
