wasn't the crash at Teneriffe with the two 747s partly due to no-one wanting to question the chief pilot as he began his take off run in order to stay within his crew duty time?
Personally, I've had issues whilst going through training. Like ultra low flying over the highlands as my instructor/cowboy took control for the most interesting part of the trip to relieve the boredom. On the frontline, I've flown with the staish, squadron bosses etc, and I think that they are aware of the problems and encourage young pilots to exercise their rights as captains. Maybe I've just been lucky with the dudes I've flown with.
