From 1948 to 1949, Stapp headed research project MX981 at Muroc Army Air Field (later renamed Edwards Air Force Base) for the purpose of testing the human tolerance for g-forces during rapid deceleration. The tests used a rocket sled mounted on a railroad track with a series of hydraulic brakes at the end. Initial tests used a humanoid crash test dummy strapped to a seat on the sled, but subsequent tests were performed by Stapp, at that time an Air Force captain.
