A new National Geographic special coming up on Sunday, February 12 is promising to answer a whole lot of questions about the grounding of the Costa Concordia last month. Featuring first-hand accounts of American survivors who share their own home video, Nat Geo will present Italian Cruise Ship Disaster: The Untold Stories.

"How did the ship sink? Could it have been prevented? Why weren't the passengers warned earlier? What are the similarities to and differences from the Titanic?" asks and answers NatGeo in the special episode Sunday night.

Costa Concordia was carrying more than 3,200 passengers and 1,000 crew, including Americans Sameer and Divya Sharma from Massachusetts and 18-year-old Amanda Warrick who was traveling with her older brothers. On Friday the 13th, while the Sharmas shrug off any bad luck, the Warrick siblings toss out the idea that "something's gonna happen."

Soon, the ship detoured off course and hit the rocks. Amanda describes the immediate impact, telling NatGeo, "At first there was a tilt and a shake of the ship, that's when tables and glasses started crashing. I was kind of in shock, I remember immediately standing up and looking at my brothers. I was just kind of speechless and silent."

Italian Cruise Ship Disaster: The Untold Stories includes in-depth stories from passengers and staff on board as well as Coast Guard rescuers with home video, some never before seen on U.S. television, and reconstruction of the sinking of the Costa Concordia as it happened.
