I fly the B777 and given all the facts provided by the officials a catastrophic depressurization is highly unlikely in my opinion.
In the scenario mentioned above if the depressurization was catastrophic crew intervention would have highly unlikely. In this phase of flight the aircraft would have been on autopilot in LNAV/VNAV modes. As such the aircraft if able to maintain flight would have continued on its programmed route. However the evidence provided so far suggests that the aircraft turned 180 degrees and made several course changes after.
Any of you so called experts actually received high altitude training in a pressure chamber, simulating a rapid depressurization? I have.
