On April 10, 1912, the Titanic set sail for New York City from Southampton, in England. Four days later, the ship struck and iceberg and sank in the frigid waters of the Atlantic.
The rest of the story has been the subject of countless books, shows and films about the thousands of people who traveled on her maiden voyage, the dramatic events of the final few hours, and legend of the "unsinkable" ship.
Bob Ballard, the explorer who discovered the Titanic wreckage, talks about why the Titanic still matters.
