I take it Sully is the call sign, and the guy shouting “fail recover” is the pilot? Judging by the altitude and airspeed it looks like he stalled after he turned it, then couldn’t get it to recover, but the system kicked in once it had enough airspeed to regain lift (after falling from 17k feet to 5k???) pulled 9.1 Gs then you see it level off nice once the nose pitches back down. Then we hear “Sully knock off” which I assume they mean he lost consciousness?
