Fastest Train in the World: U.S. Air Force Rocket Cars - Full Documentary (720p HD)

This educational HD video is about shows the U.S. Air Force rocket sled used for aircraft and aerospace research. Unlike the fastest supercars, in aircraft engineering design, a rocket is powered by rockets and it does not have wheels and rides on a special railroad track. A rocket sled holds the land-based speed record for a vehicle, at Mach 2.5, that is 1600 miles per hour. Maximum speeds for unmanned is mach 8. How fast does a bullet train go? Only about 250mph.
