well don't a lot of the commercial aviation pilot rely solely on the autopilot and navigation systems, hence they are not pre-occupied for every waking second of the flight? Wouldn't that make it like other similar disasters where the pilot's lack of attention was the fault? I don't know the actual cause of this crash, but others have occurred in this manner before. I still find it pretty bizarre sometimes considering how stringent flight training and certification has been in the US, but I don't know about all the specifics of the industry so I shouldn't generalize.
