Quick to point the finger arnt you? To me it sounds like something else. Nowhere did I see a mention of being unconfident either. He obviously had enough time to think about his reactions. The plane was turning, he made a correction and got no response. Even with full rudder input.
OK...I stand corrected. Perhaps this wasn't the problem here. However, since the engine is turning counter clockwise, if the airplane did stall, the right wing would drop as indicated.
