For the last 35 years, people have been exploring the remains of the most mythical wreck in the world, but now, 108 years after it sank, the Titanic is under threat.
Resting at more than 12,500 feet below sea level and 380 nautical miles off the coast of Newfoundland, the most famous shipwreck in the world is being consumed by iron-eating bacteria.
This slow and irreversible decay, according to the most concerned experts, will sweep away all the secrets of the famous liner within a few decades. With a new approach, this documentary relates the underwater odyssey of the greatest Titanic expeditions and the evolution of the most scrutinised shipwreck in the world.
From the epic discovery of the wreck by a French-American team in 1985 (after some 20 failed attempts) to the exploratory missions led by James Cameron, who managed to light the wreck scene like a Hollywood film set and venture inside the ship thanks to remote-controlled robots, and to the treasure hunts that brought back over 5000 vestiges - we experience the incredible thrill of these extreme dives.
Titanic: Into The Heart Of The Wreck airs Sunday 16th May at 7:30pm on Channel 4.
