There are two little known facts about the HMS Titanic.  First, the American Bar Association conducted a mock trial to determine the liability of the White Star Line against those passengers and crew who perished in the sinking.  Second, a survivor of the sinking, one Lady Duff Gordon, was involved in a contract dispute resulting in an appellate case studied by law students across the country.  Actually, the third little known fact is that a great actor auditioned for the role of Jack Dawson.  You can find the newly re-discovered audition here.
