Eli Beeding
Encyclopedia
Eli Lackland Beeding Jr. (born December 17, 1928) was a U.S. Air Force captain and rocket test subject. In 1958, a series experiments using a miniature rocket sled began at Holloman AFB under the supervision of Colonel John Paul Stapp and Captain Beeding. Participants rode the "Daisy Sled" (so-called because it was originally designed to be air, and not rocket, powered) at various speeds and in many different positions — even head first — in an attempt to learn more about the g-force
force limits of the human body.
On May 16, Capt. Eli Beeding prepared to make a 40 g run. The Daisy shot down the track, reached a top speed around 35 mph, and came to a screeching halt in less than a tenth of a second.
"When I hit the water brake," Beeding recalled in a recent interview, "It felt like Ted Williams had hit me on the back, about lumbar five, with a baseball bat." Beeding had barely informed flight surgeon Capt. Les Eason of his troubles when he began to experience tunnel vision and passed out.
It was a scary moment, since the standard protocol for shock would be to elevate Beeding’s feet. Yet there was a chance his back was broken, in which case he shouldn’t be touched. Taking a calculated risk, Eason and Tech. Sgt. Roy Gatewood gently moved Beeding onto the side of the sled and elevated his feet. Ten minutes later, Beeding emerged from shock and was rushed to the base hospital. Doctors determined his back was only badly bruised. "I thought that was the big excitement of the day,” Beeding recalls. "But later my boss came to me and said, ‘The chest accelerometer tracing shows you got 82.6 g!’"
Subsequent tests with bears showed that the reading was not a fluke, and that Beeding had indeed endured a massive g load. When word got out, the young Captain made headlines as the man who had topped John Paul Stapp’s g-force record. Beeding however is quick to point out that he rode the sled backwards, and that his time at 83 gs was “infinitesimal” compared to the 1.1 second durations Stapp faced during his own tests. “That doesn’t sound like much (time),” Beeding notes, “But I guarantee you, having been through it at lesser durations, one second is an eternity.”
Still, the incident was wholly remarkable and made Beeding a hero and, for several decades thereafter, his name appeared in the 1959 Guinness Book of World Records.
Beeding later retired from the Air Force and now lives in Colorado.
G-force
The g-force associated with an object is its acceleration relative to free-fall. This acceleration experienced by an object is due to the vector sum of non-gravitational forces acting on an object free to move. The accelerations that are not produced by gravity are termed proper accelerations, and...
