Pilot engineer
Is it reasonable to assume that anyone with absolutely no engineering knowledge can ever be as safe a pilot as someone who has. Or is the engineer pilot more likely to make assumptions and create problems that put him under pressure. Granny Smith drives down M1 with no oil gets to London, engine knackered. Billy Smart drives down M1 hears big ends, stops gets out in hurry, killed by passing lorry. If you get my drift!
