I'm sorry but some of this is absurd.
The simple reality is that flying a complex aircraft is simple, right up until it's not. Every thread specific to controlled flight into terrain seems to come back to fundamental errors in judgement. There is no conspiracy, no international espionage or any dime store novel stuff.
The folks who man the pointy end of the aluminum tube accept the stark reality that any momentary lapse in judgement might cost the lives of those entrusted to their care. Accordingly a tremendous interest exists in exploring the possibilities, in some instances like 447 all that exists for now is that curiosity and speculation and the impossible to answer "what happened?" and "could I recognize and prevent the tragedy if it was me?".
Here is seems a very simple reality that all of the "rules" exist for a reason and a harsh reminder that fate is still the hunter....
