Quote from Lucrum:
Actually the really stressful situations are relatively rare. Major mechanical/electrical failures at night in bad weather would be one. Looking out the windscreen and seeing another aircraft close enough to wave at the other crew or seeing the ground rapidly approaching comprise most of the others.
Oh I just remembered another. Waking up and realizing you didn't wear a condom on your joystick when riding that flight attendant you only met the day before.
