So I stopped the roll at 140 degrees — according to the flight data recorder— and kind of split-S'd it from about 18,000 feet to about 12,000.
The autothrottles were on, with max climb power selected, and as soon as the nose came through I realized I was really ripping. I had to reach over with my left hand, disconnect the autothrottle, sweep them back to idle, reach back and reacquire the yoke. There was a lot of wind noise and I could feel the airplane entering mach tuck — buffeting — and I thought if I don't pull hard enough it's not going to matter, and if I pull too hard it's not going to matter! After I got the nose back near the horizon, I was kicking the rudders back and forth trying to keep him off balance. Fortunately Andy and David were able to subdue him.
