Richard Noble, reached 633 mph (1,019 km/h) driving a turbojet-powered car named Thrust2 across the Nevada desert in 1983. In 1997, he headed the project to build the ThrustSSC, driven by Andy Green, at 763 mph (1,228 km/h), thereby breaking the sound barrier, a record first for a land vehicle (in compliance with Fédération Internationale de l'Automobile rules).
The task of driving the BLOODHOUND SSC will fall to Wing Commander Green, who will lie feet-first in the BLOODHOUND SSC. As the car accelerates from 0 to 1,000 mph (0 to 1,609 km/h) in 42 seconds, he will experience a force of approximately 2.5g (two-and-a-half times his body weight) and blood will rush to his head.
To slow the vehicle, Green will deploy airbrakes at 800 mph (1,300 km/h), and subsequently parachutes at 600 mph (970 km/h), with disc brakes used below 250 mph (400 km/h). As he decelerates, experiencing forces of up to 3g, blood will drain to his feet, with a risk of driver blackout. To condition his body for these intense g-forces, he will practise in a stunt aircraft, flying upside-down over the British countryside.
