MUMBAI: An expedition by The History Channel to the Titanic wreck site, conducted in August 2005, produced never-before-seen footage that could completely rewrite the final moments of the world's most famous sunken vessel.

The special Titanic's Final Moments: Missing Pieces airs in the US on 26 February.

Using high-definition photographic equipment, an internationally acknowledged team of experts has located brand-new information that maritime historian Simon Mills has termed "possibly the most significant pieces of evidence since the wreck was located in 1985".

Veteran shipwreck divers and hosts of The History Channel series Deep Sea Detectives, Richie Kohler and John Chatterton joined a team of maritime experts on the Russian research vessel Akademik Mstislav Keldysh. The trip was a gamble: heavy on resources, but highly speculative, with a legitimate possibility that they would come back empty-handed. They were in search of new clues whose existence had long been talked of in Titanic expert circles, rarely seen but never examined for their role in Titanic's sinking.

They cruised the known debris field days in front of an oncoming storm, racing against time and the elements to try and find new clues from Titanic's final moments.

What exactly did they find, and why is it being called "the missing link" in the Titanic story, the piece of information that can help settle issues that experts have debated for years? Kohler and Chatterdon are joined by renowned naval architect Roger Long, historian Simon Mills, and a host of other experts on a deep-sea search for clues and in the raging debate as to what they really mean.
