Eerie new audio released by US Coast Guard believed to be moment of Titan sub implosion

The Titan submersible disaster may have happened a year and a half ago, but we're still learning new things about what exactly happened.

The sub, which was on an expedition to the wreckage of the Titanic, imploded due to the immense pressure of the water on June 18, 2023.

Oceangate CEO Stockton Rush, British businessman Hamish Harding, aged 58, and 77-year-old former French navy diver Paul-Henri Nargeolet lost their lives.

19-year-old Suleman Dawood and his dad, Shahzada, a 48-year-old British-Pakistani businessman, were also on the sub and died from the explosion.

In a new development to the disaster, the US Coast Guard has released audio footage that is believed to capture the final moments of the doomed sub.

Recorded by a National Oceanic and Atmospheric Administration device, the audio is certainly disturbing.

The 'suspected acoustic signature', as officials are calling it, reveals an incredibly loud bang followed by a large rumble.

The tragic incident sent shockwaves across the world in 2023, though it did not surprise Karl Stanley, a close friend of Rush.

Stanley went on a trip in Titan back in 2019, and he certainly had some concerns.

During an interview with 60 Minutes Australia, Stanley was asked if Rush had a ‘death wish’, to which he replied: “The only question is, ‘When?’ He was risking his life and his customers’ lives to go down in history. He’s more famous now than anything else he would’ve done.

“He quite literally and figuratively went out with the biggest bang in human history that you could go out with, and who was the last person to murder two billionaires at once, and have them pay for the privilege?”

When asked what he believed caused the implosion, Stanley said: “There’s no doubt in my mind that it was the carbon fiber tube that was the mechanical part that failed."

During his trip with Rush on the sub off the coast of the Bahamas, Stanley spoke claimed he heard ‘loud, gunshot-like noises … every three to four minutes’.

Stanley said he reached out to the OceanGate CEO in a series of calls and emails following the trip to voice his concerns.

There is an area of the hull that is breaking down. It will only get worse,” he wrote to Rush in 2019.

Stanley added: “I literally painted a picture of his wrecked sub at the bottom [of the ocean] and even that wasn’t enough.”
