Organfreak;
Regardingf what was on the PF's PFD/ND displays, it has been argued before, but inconclusively, like the argument that the PF was following the FDs. We just don't know and there is no data which tells us that this is what occurred.
What's more, once open, those kinds of doors swing both ways - as much as one may be totally convinced that one's notion is correct regarding what occurred and why, someone else may posit an entirely reasonable counterexample and there you are...mere theory, no fact, no conclusion or worse, dangerous conclusion(s).
We are not paralyzed; we are in a new "evidence space" which directs responses differently.
