It's Titanic at 100: Mystery Solved, out on DVD from The History Channel. Here's what they have to say for themselves:
As the 100th anniversary of Titanic's sinking approached, a team of scientists, engineers and imaging experts joined forces to answer one of the most haunting questions surrounding the legendary disaster: Just how did the "unsinkable" ship break apart and plunge into the icy waters of the North Atlantic on April 15, 1912? Two years ago, HISTORY took part alongside the world's top underwater experts in the most thorough and exhaustive study of the wreck ever made. The undertaking yielded unprecedented new discoveries and the first comprehensive map of Titanic's watery grave, helping specialists solve the century-old puzzle of what went wrong -- and determine who or what was responsible.
TITANIC AT 100: MYSTERY SOLVED documents this mission, captures the high-tech mapmaking process, unveils astonishing pieces of never-before-seen wreckage and presents the expedition's unexpected findings. Unprecedented new technology and expertise was used to create a precisely detailed portrait of the entire fifteen-square-mile patch of ocean floor where Titanic came to rest.
In the twenty-five years since the wreck was located, no one had ever explored and mapped the entire site â€” nearly half the area remained unseen and unknown, and significant portions of the ship, which could reveal how it broke, were missing. Now, after 100 years, every inch of the entire site is finally known, and every piece of the ship documented exactly where it landed on the ocean floor a century ago. See newly discovered pieces of the ship for the first time, follow the expedition's new finds, and come to learn the definitive story of how the ship broke apart. TITANIC AT 100: MYSTERY SOLVED will answer the biggest questions about Titanic: did she have a fatal flaw, and if so, who or what was responsible?
