Personal opinion in response to the earlier post: in considering the possibility that the PF was so preoccupied with a roll PIO that he basically "tunnel-visioned" out his pitch situation (due to ALTN 2 law providing almost double the roll rates of ALTN 1 or normal law), his last comments on the CVR contradict that scenario. He states that he had the stick back the entire time, implying that that is exactly what he intended to do. Why he chose to do that we will never know. Whether his training or experience did not provide him the tools he needed, whether the design itself bears some blame, or whether he simply did not meet the challenge on that day.
One way or another, he used the best judgment he could manage at the time, and it steered him wrong. "But for the grace of God", any of us could be there in his place.
