USAF Colonel John Stapp tests rocket sled to determine ejection safety for pilots traveling at supersonic speeds

The video describes a groundbreaking experiment at Holloman Air Force Base, where Lieutenant Colonel John P. Stapp rides a rocket sled to test safety measures for pilots ejecting at supersonic speeds. The sled, equipped with 4,500-pound thrust rockets and no wheels, uses slippers to glide down a track. A water brake system controls deceleration, and a slow-motion camera captures the effects on Stapp. Reaching 421 mph, Stapp emerges unscathed, highlighting the experiment's success in enhancing pilot safety.
