A New Doc Features the 'Knocking' Heard on the Doomed Titan Sub

A new documentary set to be released in March 2024 features unusual knocking sounds that were recorded during the search and rescue mission for the OceanGate submarine that vanished in 2023.

The submarine eventually imploded beneath the waters of the Atlantic Ocean, killing everyone on board. Yet, the knocking sounds have remained a mystery. Was it the ship's passengers calling for help or some other phenomenon?

Titan Sub Goes Missing

Back in June 2023, OceanGate’s Titan submarine took five passengers deep beneath the waters of the Atlantic to explore the wreck of the fabled Titanic. 

Yet, approximately 1 hour and 45 minutes into the journey, the submarine lost contact with Polar Prince, a Canadian expedition vessel, per People. 

Search and Rescue Missions

After losing contact with the submarine, the Polar Prince carried out the initial search and rescue attempts, which was in line with protocol. 

However, after failing to locate the OceanGate vessel, they were forced to call on assistance from the U.S. Coast Guard.

Media Followed the Disappearance of the Submarine Closely

The media carefully followed the incident by the second as it became a race against time to find the missing submarine due to its limited oxygen that was set to run out after 96 hours. 

Unfortunately, the vessel ran out of oxygen on Thursday, June 22, without being discovered, per The Independent. 

OceanGate Vessel Implodes Not Far from Titanic Site

It was later revealed by Rear Admiral John Mauger of the United States Coast Guard that the submarine had imploded near the wreckage of the Titanic. 

Coast Guard crews discovered several debris fields that contained major pieces of the OceanGate vessel, including almost the entirety of the pressure chamber, according to The Guardian. 

Coast Guard Mentions Banging Noises Picked up by Sonar Buoys

During the initial search and rescue mission, reports of unusual banging noises were picked up by sonar buoys.

Now, a new documentary set to air on Britain’s Channel 5 features several mysterious knocking sounds reported during the search for the submarine in 2023.

Minute by Minute: The Titan Sub-Disaster

On March 6 and 7, a documentary titled “Minute by Minute: The Titan Sub Disaster” will air in the U.K., which sheds light on the day the submarine disappeared. 

A trailer for the documentary shared by the popular British social media giant UNILAD reveals several noises that resemble banging or knocking that were heard during the search and rescue mission. 

Eerie Audio Heard During the Documentary’s Trailer

The short clip hears the documentary’s narrator refer to the reports of knocking, which come in 30-minute segments, and proceeds to play the audio. 

At the time, many were hopeful this was a sign that the passengers aboard the underwater vessel were alive and calling for help. 

Somebody Is Making the Knocking Sounds

Former Navy submarine captain, Captain Ryan Ramsey, shared his thoughts on the knocking sounds, claiming, “The symmetry between those knockings is very unusual.”

He continued, “It’s rhythmic; it’s like somebody is making that sound, and the fact that it is repeated is really unusual,” per People. 

Reports of Sounds Began Spreading in the Media

During the initial search and rescue mission, reports of unusual banging or knocking sounds were confirmed by the U.S. Coast Guard.

In a statement, they confirmed a Canadian P-3 aircraft “detected underwater noises in the search area.”

Initial Rumors of Noises Were Not True

Rumors began circulating online that the noises were, in fact, coming from the inside of the missing submarine. However, a U.S. Coast Guard Petty Officer, Briana Carter, later denied these claims. 

“We don’t have anything at this time indicating any implosion or banging,” she said (via People). 

OceanGate Submarine Documentary Set to Shed Light on Fateful Day

The new documentary is set to shed insight into the final moments of the five people aboard the OceanGate submarine. 

Whether or not the initial sounds confirmed by the Coast Guard had anything to do with the vessel or the passengers within is still up for debate. However, the new documentary may give everyone a better understanding of what happened on that fateful day.
