You are like the child in the story Emperor's new clothes. You are not súpposed to say this. For every simple pilot error due to lack of skill, lack of knowledge of the system or poor decision making as an expert you are supposed to throw up some outlandish human behaviour theory to be counted as an expert. Inquires are not supposed to apportion any blame but to find root cause which off course must always be outside the cockpit. Ironically on another thread there's discussion on experiment on A350 long haul flights with single set of crew, one pilot in cockpit and the other one in crew rest. All pilots feel that's dangerous and two must be in front. While as we see Aircraft incidents/accidents happen with two, three or even four in front. In a A320 ferry the deadhead crew also came to cockpit four of them indulged in interesting conversation nobody monitored the aircraft. Due to wind change speed hit VMO, one pulled the speed brake the other pulled the thrust lever disconnecting the ATHR which was reengaged but speed brake was forgotten so speed going south and triggering alpha prot disconnecting the AP. This caused altitude bust by 3000ft. Interestingly the genesis of Airbus FBW is in the fact that Bernard Ziegler it's master mind built it so because he was pissed off with French pilot's unions attitude that pilots never make mistakes and it's immoral to blame pilot if they are dead. He disliked this elitist attitude of the pilot community which at least in Europe came from a influential class. He said this aircraft why! Even my concierge can fly. He had even received death threats. You may read a very interesting 2014 article by William Langewiesche on AF 447 in Vanity fair.
