Surprising item which survived OceanGate submersible tragedy as footage captures sound of implosion

Officials discovered a surprising item from OceanGate's Titan submersible while sifting through the remains of what was left from the tragedy.

Back in June 2023, OceanGate's Titan submersible dominated headlines after the once-in-a-lifetime voyage to the darkest depths of the Atlantic Ocean turned to disaster.

The 21-foot sub and the five explorers onboard were planning on visiting the Titanic wreckage, some 12,500 feet below surface, off the coast of Newfoundland, Canada. However, just one hour and 45 minutes into its descent and the US coast guard lost all contact with the crew and passengers.

The authorities confirmed the Titan was destroyed by a 'catastrophic implosion' due to intense water pressure and failed materials.

All passengers onboard were instantly killed.

The victims were later identified as OceanGate's CEO Stockton Rush, 61, Paul-Henri Nargeolet, 77, a deep-sea explorer from France, Hamish Harding, 58, a British businessman, Shahzada Dawood, 48, a Pakistani-British businessman and his 19-year-old son, Suleman.

Amid an upcoming Netflix documentary detailing the tragedy, a recently released video from Discovery's own doc on the Titan revealed how the US Coast Guard recovered the submersible and the personal items they found in tact.

Implosion: The Titanic Sub Disaster, which aired on the Discovery Channel on Wednesday (May 28), showed how officials discovered a pen belonging to OceanGate CEO Rush fully intact.

They also found business cards, Titanic-themed stickers, and clothing. Human remains were later discovered, which helped officials confirm the passing of all five passengers.

Last week, chilling footage capturing the sound of the explosion was released as part of the Discovery doc.

Wendy Rush, the OceanGate CEO's wife, could be seen monitoring the vessel's descent when she heard an external noise that caused much worry.

While Wendy waited nervously to see what had happened, she asked with a nervous smile: "What was that bang?"

Tragically, that was the sound of her husband's vessel imploding with him inside of it.

But just moments after that, Wendy received a message from the sub giving her the assumption everything was going to be alright.

In the documentary, a narrator explains: "She mistakenly seems to think everything is OK, but in fact it's taken longer for the message to arrive than the sound of the implosion. Everyone onboard is dead."

On June 19 2023, the US Coast Guard launched a large-scale search and rescue operation when the vessel failed to resurface or make contact almost 24 hours on.

Two days on from the Titan's disappearance on June 21, sonar crews taking part in the search picked up 'banging noises', giving false hope that the passengers are still alive.

In reality, they died instantly after the vessel imploded.
