Here is my theory on the ending. In the film the ship arrives in New York and repairs are immediately underway as we hear drilling sounds on the deck and we see a crane lifting up part of a mast on the forward deck. Many flags of celebration are waving above the ship and there is a spectator's platform adjacent to the ship with many people watching. My guess is, the Titanic is inspected for damage and parts of her hull and decking are replaced. The enormous amount of cargo and mail that is still sealed in bags in the cargo hold is removed and the media make a novelty out of reading some of the letters that are still waiting to be posted to people in America. The media and special VIPS are given a guided tour inside the wreck while repairs are still underway and some decks are off limits. Furniture is removed and possibly restored or auctioned off, and personal belongings from the passengers and crew are returned to their relatives.Do you think it became a museum, like in the Arthur C. Clarke novel Imperal Earth, which also features a raised Titanic?
