Unexpected item from Titan sub stayed perfectly intact following implosion

When the doomed OceanGate Titan sub imploded during a voyage to the Titanic wreck back in 2023, killing five passengers, only one item remained perfectly intact.

For those in need of a reminder, the underwater exploration firm's CEO and co-founder Stockton Rush lead the fatal mission in June of that year, promising four other crew members views of the most famous shipwreck in history.

British billionaire Hamish Harding was also on board, along with French diver/Titanic expert Paul-Henri Nargeolet, and father and son duo Shahzada and Suleman Dawood.

The group were crammed into the 22ft long, 9ft wide and 8ft high vessel, which disappeared just hours into the journey to the deep.

Contact between the Titan and its mothership was lost about 435 miles (700km) south of Newfoundland, Canada, with a rescue mission subsequently being launched.

The US Coast Guard later announced that the ship had 'catastrophically imploded', after debris was discovered near the wreck of the Titanic, 12,500ft below the surface, with everyone on board having been killed immediately.

Ahead of next month's release of Netflix's upcoming documentary, Titan: The OceanGate Disaster, it has been revealed that one object previously held by Titan sub passengers was discovered in the wreck in perfect condition.

The Coast Guard responsible for determining the fate of the submersible found a pen whilst sifting through the vessel's remains that year.

It was later determined that the pen had been owned by Stockton Rush.

A number of other, largely destroyed items were also discovered in the wreck, including a business card and a batch of Titanic-themed stickers.

Fragments of clothes were also found at the tragic scene, along with a collection of human remains, all of which were catalogued by the Coast Guard's Marine Board of Investigation.

News of the pen's discovery was first made public recently by producers of a new Discovery+ documentary about the disaster, titled Implosion: The Titanic Sub Disaster, who interviewed a member of the Coast Guard about the process of sorting through their findings.

The official explains in said doc that the Titan's 'endcap' was found still completely intact.

"Let's consider the endcap to be a bowl, a mixing bowl," he began. "Items that were inside of the Titan at the time now become incased inside of the endcap."

"We were all just kind of getting all-hands-in and separating what needed to be considered as human remains and what was just other wreckage pieces. As we were pulling it apart that is how we realized it was Mr. Rush's clothing."

The official continued: "It was a piece of his sleeve that survived, not the whole suit, just that.

"Inside of the sleeve of it was the ink pen, business cards and stickers for the Titanic and there was nothing else but that."
