A chilling audio recording of the final moments of the doomed OceanGate submarine, which exploded at the bottom of the Atlantic Ocean last year, has finally been released to the public.
Rescuers tried to remain hopeful after they lost contact with the Submarine as it traveled to the Titanic wreck last summer.
During the rescue efforts, the surface crew hears banging noises during 30-minute intervals.
The recording gave hope to the rescuers and the public that the crew was safe and could be rescued.
Tragically, all five passengers died as it was believed the subdermal imploded.
A new British documentary from Channel 5, “The Titan Sub Disaster: Minute by Minute,” has released the haunting audio for the first time.
The audio, which sounds like someone knocking against metal, could be heard in a series of periodic bangs.
The documentary also shared reactions from rescuers when the audio was heard for the first time.
“It could be somebody knocking. The symmetry between those knockings is very unusual,” former Navy Submarine Captain Ryan Ramsey said in the documentary.
“It’s rhythmic, it’s like somebody is making that sound, and the fact that it is repeated is really unusual,” he added.
The noises were also picked up by the U.S. Navy the following morning.
However, officials cautioned the sounds could have come from another ship.
The search efforts were ultimately unsuccessful and were called off after a submersible discovered the Submarine’s wreckage.
Ten days later, officials confirmed that they had recovered human remains from inside the wreckage.
Investigators believed the submarine likely imploded just an hour and 45 minutes into its descent, at around 12,000 feet below sea level due to immense pressure.
The five victims included:
OceanGate CEO Stockton Rush, 61
French Titanic expert Paul-Henri Nargeolet, 77
British billionaire Hamish Harding, 58
Prominent Pakistani businessman Shahzada Dawood, 48, and his 19-year-old son, Sulaiman Dawood
