The Need for Speed The Monkey Cage returns from its tour of the USA, as Brian Cox and Robin Ince take to the stage of the BBC Radio Theatre to look at the science of speed. They are joined by comedian and former motoring correspondent for the Daily Telegraph, Alexei Sayle, Land Speed Record Holder Andy Green and Professor Danielle George from the University of Manchester. They'll be looking at the engineering challenges of creating the fastest vehicle on the planet, and whether the limits to human speed are engineering or the laws of physics themselves.
