With regard to deficiencies in training, I can appreciate that the initial handling of the aircraft left much to be desired (assuming a climb was not intended) but once stalled the handling wouldn't have been anything like nominal so 'normal' training wouldn't have been much use would it ? The thing I struggle with is how the concept of a stall was outside their conceptual universe. That is pretty fundamental and nothing to do with practicing handling skills or incremental training. Sympathy for the captain though as without knowledge of the earlier climb excursion he was bowled a pretty short ball.
