That's really quite interesting but reminds me of why I never wanted to be in the airforce. That's a whole heap of useless nonsense to have to go through. Flying planes really isn't that hard.
Quite right, flying a plane isn't hard. What is hard is managing all the equipment and personnel, running a detachment in a war zone and still having to operate an aircraft in a hostile environment.
Pilots in the Air Force have to be able to cope with all the "Officer" stuff as well as maintain a level of flying that is simply not comparable to anything outside of the military. Because of this there is a challenging selection process that aims to find those that are POTENTIALLY able to cope with those challenges. Of those that apply most wont be up to it, nor will a number that meet their limits during their training.
Nothing in the selection process is nonsense, all of it has a purpose and is very specifically designed to highlight those with the qualities that histories lessons has told us that we need.
