Sonic Wind Rocket Sled New Mexico Museum of Space History in Alamogordo, NM

This sled was mounted to a railroad track with a bunch of rocket engines mounted to the back with a person sitting in the seat. It was lit up and sent off down the track at a ridiculous speed. The guy that did most of these tests, John Paul Stapp, got up to 46 G's of force on his body, the most of any human.
