Just a thought to consider: once the plane is in a spin full up elavator garantees that it will stay that way all the way to the ground. I have had it happen to me! You would swear up and down that it was something else.

When a plane is that far away it can stall very easily without you even knowing it. It starts it's spin to the ground and then you hit full up elevator and that keeps it going. I'm not saying it couldn't be something else but that is what it sounds like.
