History may be about to entirely change upon the newest evidence presented by a Channel 4 documentary, concerning the sinking of the RMS Titanic. New evidence suggests that the liner's doom may have been caused by a huge fire on board, not by an iceberg collision in the North Atlantic.

The cause of one of mankind's biggest disasters had always been pointed out to the iceberg, which was further immortalized on the Leonardo DiCaprio-led film, "Titanic," in 1997. However, experts have claimed of a fire in the ship's hull, which according to research had been burning for almost three weeks, leading up to hitting an iceberg.

Senan Molony, a Titanic researcher for more than 30 years, studied a series of photographs taken by the liner's chief electrical engineers before it left for New York, from Southampton in April 1912. According to The Telegraph, experts have previously accepted the theory of a fire on board, although the newest analysis based off of rarely seen photographs led researchers to believe that the fire was to blame, and is the primary cause of the ship's ill fate.

"We are looking at the exact area where the iceberg stuck, and we appear to have a weakness or damage to the hull in that specific place, before she even left Belfast," said Molony. The researcher stated that he had identified 30 feet-long black marks along the front right-hand side of the hull, just behind where the ship's lining struck the iceberg.

Presenting his research in a Channel 4 documentary, "Titanic: The New Evidence," Molony claims the ship was reversed into its berth in Southampton in attempt to hide the marked side from passengers. "The fire was known about, but it was played down. She should never have been put to sea," Molony added.
