Nearly everyone has at the very least heard of the Titanic, thanks to that blockbuster James Cameron epic that made Leonardo DiCaprio and Kate Winslet household names. But the sinking of the RMS Titanic—at the time the largest ocean liner in the world and widely reputed to be an "unsinkable" ship—during its maiden voyage in April 1912 has been riddled with mystery in the century-plus since.
Now, Titanic historians, wreck analysts, descendants of Titanic passengers and personalities like Downton Abbey writer-producer Julian Fellowes aim to uncover those mysteries in a new edition of How It Really Happened with Jesse L. Martin. The two-hour special investigates both the 1912 Titanic shipwreck that claimed the lives of 1,500 people and recent underwater voyage to its ruins, which have uncovered new secrets around the Titanic sinking and produced similarly tragic outcomes.
