Interior view of the Northrop “Gee-Whizz” Decelerator Sled on display in the R&D Gallery at the National Museum of the U.S. Air Force. This vehicle was developed to test the effect of deceleration forces on humans and related equipment as encountered in aircraft crashes, ditching, rocket-powered seat ejections and parachute-opening shocks.
