Wow.
I'm disappointed I didn't get any response from pilots to my last question, but that isn't going to hold me back from saying I think some of you (Bearfoil) are appearing to be frighteningly closed to the notion that the airplane may well have been just fine, but the PF screwed the pooch.
Good grief man, from what we "know" so far, it's the most logical solution to all questions.
Now, why he might have done so leaves all sorts of questions to answer, but all of this mind numbingly tedious examination and re-examination of every nitty gritty detail of the aircraft and suppositions of failures can surely wait until the rest of the data is shown to us all?
