Hi Zorin. When you get well away from the initial point of stall, new things come into play.
CL now depends on Aspect ratio, thickness ratio and Reynolds number in addition to Alpha. Remember this reference we discussed a few months ago?

Pitching moment can change. CD continues its increase fairly smoothly. It isn't the same old stall you experienced when you nibbled on the edges of it in training.
I think the deep stall description is warranted. Sixty-one degrees final AOA was closer to Broadside to the wind than to flying.
Ok, fair enough. I suspect there are quite a few people in Paris and Toulouse right now trying to find out when the door to recovery was slammed shut. Unfortunately we have precious little data about what happens when you try to get the nose down in that condition. It appears that there was some response when they tried, so I'm not entirely convinced they were in a locked-in stall...
