Dozy,
The indecisiveness and lack of definitive action on the part of PNF killed those people just as surely as did the (apparent-- I'm waiting for the final report) incompetence of the PF. Your arguments are pure obfuscation and, AFAIC, stem from a desperate need to be right, no matter what.
I was very impressed with your careful and sober-sided analysis of the software stuff, but as far as your insistence on what is really only subjective opinion, and the utter lack of respect for other pilot's differing opinions, makes me feel that the most appropriate response possible to all of your nonsense was, and still is:
zzzzzzzzzzzzzzzzzzzzzzzzzzzzz............................... ..
I have little doubt that almost everyone else's eyes are glazing over at your single-minded contrariness!
Other than that, have a great day!
