The Titanic is not just a monument to tragedy, but also to heroism. The ship's captain, Edward J. Smith, went down with his ship in the wheelhouse and Margaret Brown — the famous "Unsinkable Molly Brown," who was saved by the ship Carpathia — helped weaker survivors.
"When the Carpathia docked, all of her friends went off to the Ritz and to the Plaza, and they kicked back and they broke open a bottle of champagne, downed some caviar and just put their feet up and said 'oh,'" said Helen McKinney, Brown's great-granddaughter.
"Margaret never left the Carpathia," McKinney added. "She stayed on board until every one of the steerage passengers, the second-class passengers and anyone who had come over who had lost absolutely everything in the sinking, had a place to go or at least had someone to meet them and take care of them."
Questions swirl over what should happen to the Titanic now: Should it become a public memorial or private mausoleum? Tourists are spending small fortunes to travel down and see the great ship with their own eyes. Should it be salvaged or left where it lies, at final rest?
