Beeding's sled in fact deccelerated at 40.4 gs for 0.04 seconds as it slowed from 35 mph to a stop over a distance of one foot. 82.6 gs was a brief peak acceleration measured by a sensor on his chest due to elastic response of his rib cage. Beeding retired from the Air Force in 1971, later moving to Colorado where he died in 2013 at the age of 85. References United States Air Force officers American test pilots 1928 births 2013 deaths
