I've been following the progress of Richard Noble's Bloodhound project for a few years now. I recorded a Carpool with Richard in 2010. Since then they have been slowly developing this totally bonkers machine.
Richard and pilot Andy Green already hold the land speed record when they broke the speed of sound in Thrust SSC, that was just plane crazy. What they are developing now is a 1,000 mile an hour car. Insane but brilliant.
