What I don't understand about these situations is that the crew must know, if something goes wrong, they're dead. What imbues "trained" individuals with such a fatalist attitude? I'm sure that in certain third world countries getting a flying job might be difficult but, if the choice was between flying a clapped-out, under-maintained, overweight An12 / Il76 with a high probability of being involved in a serious accident and dying or becoming e.g. a cab driver and living . . .?
