...aviation medicine is to study the effect of bailing out of speeding jet planes into fiercely buffeting air. Since jet planes flying at safe altitudes are inconvenient laboratories, especially for observing the effects of rapid stops, he uses the most horrifying vehicle ever devised by man: a sled pushed on rails by a cluster of roaring rockets. As an experimental subject, he uses his own body...
Faster & Faster. Stapp's first sled ride was seven years ago. The sled, a one-rocket job, got up to 90 m.p.h. and coasted to an easy stop. Later rides were not so gentle. More powerful rockets made the new-model sleds start like frightened jackrabbits and pushed them along the rails at the speed of fighter planes. Stapp rode them all. He suffered the acceleration forces as they speeded up and the even greater forces of deceleration as the water brake (long trough of water engaging a scoop on the sled) brought them to a wrenching stop.
