Another note on the early break-up theory: the theory implies that the liner broke up at a relatively sharp angle, about 45 degrees if I remember correctly, and that the only reason the stern portion of the break up stuck up in the air was because of the double-hull that still connected the two halves. Once the stern portion was upright, the jolt unconnected the two sections, and the bow half began its journey to th bottom. The stern portion remained afloat for a while longer because of its buoyancy, and once it began to sink, it went straight down, trapping air within itslef. As it neared the bottom, the air began escaping, removing chunks of steel with it. Once it hit the bottom, all the remaining air was thrust out of the hull, and blew pieces of the hull plating out in all directions, which is why the wreckage is in such a mutilated condition, the stern section at least. Anyway, pretty good model.
