On the other hand, a thinking person might consider that a pointless and irrelevant comparison.
Well Dave, that is the point isn't it. It is wrong to say that someone is better than another based upon any of these factors. A mechanic or ground crew or engineer designing a wing is just as important in the chain of people getting things right as much as the pilot is. But it is relevant and worth pointing out that a pilot, if not competent, could very easily, cause the immediate deaths of a large number of people, whereas a doctor usually only has only one patient at a time under his care. Both roles are complex 'undertakings', but one is certainly more dramatic than the other in terms of scale of responsibility when you consider just what could happen in an instant if a pilot is not careful.
It is a huge responsibility. Most people would acknowledge that.
