Dont know if this has been mentioned before but acording to a documentary called Devil at your heels, Sammy miller was cew cheif and test driver for a world record attempt. Ken Carter wanted to jump a car over a mile wide river, he had a rocket car built to do the jump with. About 50mins in is where you first see sammy and he is rather entetaining in the footage.

If you have a bit of time on your hands have a look,
