The whole emergency theory seems to be shot down for the moment by the "fact" (I use any facts in quotes on this story) that the plane started its turn before the last radio contact from the pilots. It's remotely possible that someone other than the pilots programmed that turn, but it seems unlikely that the pilots would not have noticed the plane turning.
Of course, the evidence of the turn could be wrong. But if it's true, then we're assuming either ongoing pilot incompetence, or pilots who knew the plane was turning and didn't reveal to ground control. Occam's razor suggests the latter.
