The superstructure would amlost* intact if she hit the bottom upright... for the explosion was mostly directed upward off the metallic ship and water. The keel is a different story though... for the boilers blew straight through the bottom hull, completely anniahalating the underside. This is only what I guess, for I have never seen pictures of the wreck**.
*Besides the piched part from the initial split, she arched her back like an old black cat when she flipped.
**I am assuming the wreck has been found right? I mean, there was footage of the event... (More info would be nice of this topic too now that I think about it. Why are we hypothesizing on the ship's condition when we should know where she is? Didn't Ballard or someone go check her out on their explorations?)
AND THE SEA SHALL GRANT EACH MAN NEW HOPE, AS SLEEP BRINGS DREAMS.
