This thing is basically a rocket with a passenger seat. A rocket and a jet engine provide 47,000 pounds of thrust. 3 years in the making: built with the express purpose of shattering the land speed record, the Bloodhound SSC is expected to break 1,000mph later this year. The speed of sound is 768mph, just a bit faster than the current land speed record of 763mph from the Thrust SSC, which was designed by the same Richard Noble-lead team. Our Smash mash tops this, Pun intended.
