Lafyer Cokov has supplied the answer and I agree with him wholeheartedly.
The nail was hit firmly on the head (for me, at least) at the recent Heli-Power conference. When one of the speakers, not from the UK, was asked how he managed to keep his aviators in the service, instead of them wishing to leave, he answered that you have to ensure that their efforts are
appreciated, and that they, and their families, are well
supported.
The two words that I have underlined are considerably less today, and in some places non-existant, compared to the armed forces I joined many years ago, and, I suspect, across all 3 services and not just from the RAF, as the
RAF in Meltdown thread is showing. (Anyone else non-RAF joining in this thread? We are purple on PPRuNe!)
That is why people are looking for the door.
And stealing your airline jobs.
