Titanic at 100: Mystery Solved is a documentary from History Channel. It aired on April 15th 2012, on the 100th anniversary of the sinking.
The researchers in the documentary try to answer a 100-year old question: did Titanic have a fatal flaw? They use a complete map of the wreck site made during the 2010 expedition to investigate.
The documentary recycles footage from A Night to Remember and a brand-new animation.
