Mozella:
An interesting and worrying picture you paint. What about fear?
Fear of failing the course, sure; but more importantly, fear of dying. Doesn't that sharpen the appetite for training?
I suggest that a small degree of fear, or at least wariness, is healthy and useful in all aircrew and pax. As the latter, I need to pay attention to the safety demonstration. Flight crew who are continually wary of unexpected events can seek to prepare for them.
Has the advent of highly-reliable cockpit automation served to annul fear?
