In February 1957 a chimpanzee rocketed down the track, now 5,000 feet long,
braked to a stop, and survived a load of
some 247 g for .01 sec, with a rate of onset of 16,000 g per second.
Captain Eli L. Beeding, seated upright and facing backward, experienced the
highest deceleration peak yet recorded
on a human being - 83 g for .04 of a second, with 3,826 g per second as the
calculated rate of onset.
A team of physiologists from the Army, Navy, and Air Force had used the 50-foot
centrifuge at the Navy's
Johnsville installation to study high reentry g buildup, exposing five
chimpanzees to a peak of 40 g for one
full minute. Post-run examinations of the primates showed internal injuries,
including heart malfunctions and
internal hemorrhage.
