So, I would say that pilot error is a primary factor in this case. But, that still leaves open the question of why the error occurred and whether there is anything we can do to reduce the probability of it happening again. I highly doubt the Captain is simply stupid or incompetent given all of his experience. Perhaps, the crew was overly fatigued? People make mistakes, sometimes big ones. The question is how to reduce mistakes and how to limit damage from those mistakes.
