I think the real truth of what really happened is now lost in history, but if you read the report by Lord Mersey; you will come to the conclusion even after the sinking, no one really knew what happen, the main people who knew the facts went down with their ship.
All Except the Chairman/MD of the white star line who jumped in to a life boat, was Bruce Ismay
