One of the most ironic things about the Titanic is the fact that her sister Britannic, all but forgotten, is much more intact and preserved than her famous sister. That being said, if the Titanic had sank in several hundred feet of water she wouldnt have had time to break up. Her bow would have hit bottom,while her stern was up, settled back,probably roll on her side and sank the way the other ships did. Parks Stephenson summed it up well--the Titanic broke because she was subjected to stresses that no ship could withstand. The ocean floor was 2 miles down, and as she sank, the bow had nowhere to go but down and down. Plowing through 2 miles of ocean, with currents,depth pressures, etc. tearing away at the superstructure didn't help either. As far as the Olympic goes, yes she was refitted post Titanic, but the last time I checked her outer steel skin was not stripped away and replaced with new steel. The Olympics' outer shell was the same steel from those pre Titanic days.So the same rivets and everything from 1910 were still there.Of course I may be wrong on this but I have yet to see drydock photos of the Olympic looking like a building whose facade has collapsed in an earthquake.This is in response to the gentleman who said the refit was why Olympic ran into a U boat and didn't break apart.
