Thanks Dave, for the clarification. I've seen a finite element analysis picture of the stresses in the hull just before the break up. The structural engineer who did the analysis belives, interestingly, that the ship could not have raised out of the water more than about 12 degrees before she broke, well almost broke, in two. However, he didn't indicate the angle the stern may have rose before being flooded and pulled under by the bow.
and yet, another piece of the puzzle missing....
thanks.
