The RMS Titanic set-off on her maiden voyage on a five-day journey across the North Atlantic and sank after colliding with an iceberg in April 1912.

It was the result of a long, long chain of mistakes: a fatal series of avoidable human errors that sent Titanic and more than half of her passengers to their watery grave. Based around the official Inquiry held immediately after the event, plus evidence thats come to light since the wreck of the Titanic was discovered in 1985, this documentary will answer the question - What Sank the Titanic?­
