As Sir John Day pointed out, there was no evidence from the behaviour of the crew of any distraction or malfunction approaching the way point. Has pointed out already here, if you put yourself in a position such that a distraction would cause you to fly into a mountain then you are grossly negligent. Let’s stop grasping at straws folks. If you cause an accident in your car due to excessive speed there is little point in discussing the esoterics of whether the brakes failed, the accident would have happened regardless.
