There is no end of evidence that this has happened to some degree before, but nothing quite like this. There must be some other explanation.
I'll start off with not a pilot, but a career IT person with much background in machine/user interaction. The same thought came to me also after hearing so many truly knowledgeable pilots say the same thing. I haven't read through all of the posts on this thread....too many to do so. But has anyone raised the thought of something akin to hypoxia or carbon monoxide poisoning? These were not two rookies, and yet their behavior is beyond anything any pilot could imagine taking place in a commercial airliner. Could some fault in the pressurization or environmental systems cause them to be disoriented or partially incapacitated? It just does not seem possible that they could have made so many bad decisions along the way without realizing they were getting deeper and deeper into trouble and taking some corrective action. The fact that, as
ferry pilot stated, they made so many deliberate actions that were all wrong begs for a better explanation other than they thought they could get away with it.
