British engineers are building a supersonic car which they say will travel faster than a speeding bullet. The team raced to a new world record in 1997, breaking the sound barrier in the Nevada desert in a jet-powered car. Now they are working on a car to reach 1,000 miles per hour. Known as Bloodhound, the supersonic car will be powered by a rocket bolted to a Typhoon-Eurofighter jet engine. The engineers say the car will be able to travel the length of four football pitches every second. They’ve been working on it for a year-and-a-half and are hoping to be ready to try for a new world record in 2011.
