Legend has it that Steve McQueen and Jackie Stewart were supposed to take part in the 1970 Le Mans in a Porsche 917, but the plan fell through either because (a) McQueen couldn't get insurance or (b) the organisers threw out the entry because of McQueen's lack of experience. However, I have read that JYS wasn't a great fan of Le Mans anyway, so was it a genuine effort or wishful thinking or a publicity stunt or whatever?
