For all of you who maintain you can't recover from this type of scenario at pattern altitude, watch the video again. The intial departure was a simple stall w/ wing drop. The airplane dropped its nose and momentarily paused with no further rotation about the yaw or roll axes. After a moment, the aircraft starts to rotate, likely due to aft stick and improper right aileron trying to pick the left wing up. Spins just don't instantly happen - they develop due to continued improper inputs. This initial stall departure could have been recovered with stall/spin training and practice. I don't understand why the CFI did not conduct stall practice.
