Colonel John Stapp and Captain Capt. Eli Lackland Beeding, Jr. are 2 of history’s unknown heroes.
The duo rode the “Daisy Sled” down a track at speeds over 600 MPH and then hit a “water brake” wall, causing them to decelerate at speeds that would test the human body’s max point of surviving G-Force.
(1 “G” = human body weight on Earth’s surface…5 X 140lb. Human = experiencing 700lbs of gravitational force on the body)
