Dateline Survivor: Miracle on the Wild Coast

S1 E6: This is a harrowing, dramatic story of heroism at sea after a cruise ship starts to take on water and sink with nearly 600 people on board. Remarkably, the rescue was not led by the captain or senior officers but the ship's cruise director and her entertainment staff -- including a magician and a guitarist. Almost every moment of the crisis was captured on home video, including some heart-stopping scenes of passengers jumping off the ship and others being airlifted off the deck not long before the entire ship goes under. How did the passengers survive after some crew members abandoned ship?
