He was particularly good at forcing me to chase reliability, which in those days was not my forte. When I first joined, he said to me, ‘Why on earth didn’t you fix that flipping fuel pump at Leyton House?’ and I remember thinking how right he was, because even though at the time I believed we were doing all we could to address the problem, the bottom line was that we didn’t put enough proper research or design effort into fixing it. We should have done more, and ultimately I take responsibility for that.
