Haunting audio from Titan sub capturing moment of implosion revealed

A new audio clip has been released by investigators of the 2023 Titan sub disaster.

The eerie, 20-second recording - released this week by the US Coast Guard - supposedly captured the final moments of the doomed submersible before it imploded, killing all five passengers on board.

US deep-sea exploration firm OceanGate Expeditions began its voyage to the ocean floor on 18 June 2023, carrying five passengers - including CEO and co-founder Stockton Rush.

That same day, the ship lost contact with its team above water after travelling just 435 miles from the shore of Newfoundland in Canada, prompting a heavily-manned rescue mission.

Sadly, it was eventually determined that OceanGate's Titan had suffered a 'catastrophic implosion', killing everyone on board.

In a new update this week, however, the US Coast Guard has released a piece of audio it believes captured the final moments of the sub, as well as the five passengers travelling inside.

On 7 February, the recording was made public amid discussions about the noises that could be heard from the depths of the Atlantic during the period of the sub's disappearance.

During the initial search, global reports focussed heavily on supposed rhythmic banging from the depths of the ocean, with speculation spreading at the time that this could be the five passengers beckoning for help.

It was later ruled by the Coast Guard, as per Rolling Stone, that the supposed thumping was unrelated to the sub, which was subsequently found to have imploded during its descent on 18 June.

The newly-released audio, however, is said to have captured this tragic moment.

The Coast Guard said it was recorded around 900 miles from the sub by a National Oceanic and Atmospheric Administration device - beginning quiet, before an unnerving whooshing sound can suddenly be heard.

Investigators believe that the device picked up a 'suspected acoustic signature' of an implosion.

"NOAA's Ocean Noise Reference Station Network consists of thirteen passive acoustic monitoring sites deployed within the Northeastern continental United States," the Coast Guard added.

Traces of the vessel were subsequently discovered on the ocean floor, with many pieces found surrounding the wreckage of the Titanic, off the coast of Canada.

Presumed human remains - believed to belong to British billionaire Hamish Harding, French diver/Titanic expert Paul-Henri Nargeolet, and father and son Shahzada and Suleman Dawood - were also found in the surrounding area.

The new audio's released comes just weeks ahead of the release of an eagerly-awaited Netflix documentary about the heartbreaking disaster - titled Titan - which also vows to examine the life of Stockton Rush, and his fatal quest to become the next billionaire innovator.

"When the Titan submersible went missing, I was horrified and mesmerised by the 24/7 news coverage and global social commentary - just like the rest of the world," director Mark Monroe previously told Tudum.

"There was no context for what could have happened to those onboard, and the only touchpoint was the Titanic, a story that’s now become a grim fairy tale."
