In a newly released documentary, the terrifying tapping sound is revealed for the first time, giving rise to faint hope in the search for the tragic Titan sub.
The Titan disaster involved the disappearance of the submersible during an expedition to explore the wreck of the Titanic on Sunday, June 18, 2023.
In a gripping development surrounding the tragic Titan submersible disaster, a new documentary has unveiled never-before-heard audio that captures mysterious 'banging' sounds detected deep beneath the ocean's surface after the vessel disappeared.
For the first time in a new documentary, the sound was described as steady and regular, raising hopes that this might be a signal for help from the five men on board.
The former Navy submarine captain Ryan Ramsey tells the documentary: 'It could be somebody knocking, the symmetry between those knockings is very unusual."
He added: 'It's rhythmic, it's like somebody is making that sound, and the fact that it is repeated is really unusual.'
The new documentary marks one year after the tragedy. Additionally, the behind-the-scenes of the multi-million dollar search operation and the lessons from the disaster.
The document, "Minute by minute: the Titan sub-disaster', details the events leading up to Titan's fateful expedition to the wreck of the Titanic.
The document reveals the never-before-heard audio and includes expert analysis of the search mission that gripped the world.
At the time, some experts warned against considering the sound as evidence of life, with many suggesting the noise was likely "debris" and "junk" from the famous wreck.
Investigators believe the Titan was crushed when it began its dive into the deep waters of the North Atlantic on June 18 - before the banging was recorded.
Desperate search efforts were launched after the Titan submersible missed contact with its Polar Prince mothership while exploring the wreck of the Titanic.
After many hours of waiting for news, at the end of the second day of the search campaign, reports came that thumping noises were detected in the depths of the ocean at intervals of every 30 minutes. Experts and rescuers have redoubled their efforts to find the missing submersible before it is expected to run out of oxygen.
On board were five passengers, including tourists Hamish Harding, 58, Shahzada Dawood, 48, and his son, Sulaiman Dawood, 19, French Navy pilot Paul-Henry Nargeolet, and OceanGate CEO Stockton Rush.
However, the hopes raised by the mysterious knocking were later extinguished.
The official suggested that the sound could also have been caused by the ocean or by other ships in the area. They claimed that the Titan had collapsed under enormous water pressure, resulting in the immediate deaths of five passengers after the sub exploded.
