Mareklug, i watched an interesting documentary downloaded from youtube titles Air Crash Investigation - Pilot error where this issue is debated in more detail. I believe that the crash of Air France flight 447 also raised concerns about the ability of commercial pilots manual flying skills especially when the automated systems shut down. I have also watched the investigation from Turkish Airlines flight 1951 where Gordon Bethune (a former VP at Boeing) states that the pilots main job is to fly the airplane & they must never forget it never mind what a computer says.

As the pilots have survived this crash,they should be able to tell the investigators a great deal about what happened. I just hope it isn't Turkish Airlines all over again.
