Tangible reasons, dallas dude?
I would suggest poor flight deck crew training as the root cause.
That, and the general 'we can do no wrong' attitude that AA pilots seem to have.
It is certainly noticed by many, DD, no matter what you may perceive.
Take the Littlerock Commander, as an example.
Surely you must admit that this guy, an experienced AA pilot, had no business landing in the conditions he found that day.
Judgement, at least in this case (Cali also) seemed to go out the window.
Just as simple as that, IMO.
