From OP's link:

We live in permissive days. If one tells the aviating public that, if the donkey up front goes quiet during the early stages of climb-out, never to turn back, hackles rise and usually-reasonable folk accuse the speaker of being dogmatic. One or two almost invariably trot out some story in which the pilot turned back, got away with it and would have hit the headlines had he gone straight ahead.No doubt there are a few, although very few, situations in which circumstances might dictate turning back. But, such decisions, demanding split second action and supreme skill, are beyond the capabilities of the average pilot. It's better by far to establish a well-rehearsed emergency drill and keep in practice, so that should the engine go on strike, there will be no "shall I/shan't I" nonsense while time runs out
