The document discusses the Bloodhound SSC land speed record car project. It aims to be the first car to break the 1000 mph barrier. The land speed record has progressed over time from electricity and steam power to jets and rockets. Bloodhound SSC uses hybrid rocket/jet propulsion and advanced aerodynamics to try and set a new record. It will need to decelerate safely after reaching top speed to allow the possibility of a second run.
