She was the largest ship ever built and believed to be unsinkable. When RMS Titanic went down on her maiden voyage taking 1500 people to their death, it sent shock waves across the world and started a debate that still rages today. Why, when the Titanic received several warnings of icebergs ahead, did the captain steam full speed towards them without changing course? Two hours after the collision, the Titanic was safely afloat before she inexplicably gave way and took hundreds of passengers to their deaths. What happened to make her sink so rapidly? For the first time, investigative journalist and Titanic expert Senan Molony can reveal the real story. In a television exclusive, Titanic: The New Evidence draws on new evidence to reveal that a fire was raging in Titanic's boiler rooms before she left port, that it was kept secret and, it's now believed it led to the tragedy.
