When the titanic broke in two initially, the keel still attached the two together. At this this time the titanic's stern fell back to even level. The Titanic's sunken bow pulled the stern back up before breaking free, putting to stern in a position to sink. The stern had little to no water in it at the time. So if it was level could it have floated if the bow broke completely free or would the weight proportion pull it down anyways? Any thoughts to this subject would be appreciated.
