Real reason why Titan sub parts are still whole as video of implosion wreckage is released

The first footage shown of the OceanGate Titan submersible wreckage has revealed that parts of the vessel are still intact, and there's a reason why.

On September 16, the US Coast Guard commenced a hearing to investigate the implosion of the sub and pinpoint if there is anyone to blame for its wreckage.

Last year, an OceanGate Expedition 21-foot submersible named Titan, descended into deep waters for a tour of the Titanic's wreckage site off the coast of Newfoundland, Canada.

The expedition began at 8.00am ET on June 18, 2023, however around an hour and 45 minutes into its descent, contact with the Titan and its five passengers onboard was lost.

After a hefty search mission, the US Coast Guard confirmed that the Titan was destroyed by a 'catastrophic implosion' due to intense water pressure and failed materials, resulting in the loss of all five people onboard.

Expected to last two weeks, the US Coast Guard's hearing has revealed a slew of never-before-seen footage of the Titan wreckage along with the crew's harrowing final message.

Despite the Titan being thought to have imploded, parts of the vessel are still intact as seen in video footage and pictures released from the hearing. Search teams have also brought chunks of the submersible back to shore over the past year.

Arun Bansil, a professor of physics at Northeastern University, explained the science behind this, telling the Mirror: "Although it seems counterintuitive, large objects do not normally split apart into smithereens in an implosion or explosion.

"For example, a pressure cooker usually explodes with the top blown off but the body remains intact," he added.

"The initial failure of Titan would have occurred at its weakest links such as defects in the hull."

"Once a crack opens, however, large pieces of the hull will no longer experience very violent forces and remain more or less intact," he explained.

The US Coast Guard has listed 24 witnesses to testify in the ongoing trial, ten of which are believed to be former OceanGate employees.

One former employee, David Lochridge, reportedly voiced his concerns over the safety of the Titan sub while he was still working at the company.

Speaking at the hearing on September 17, Lochridge claimed that he was 'dismissed on every single occasion' whenever he raised his concerns.

He went on to say that OceanGate 'knew my dissatisfaction' and would not let him attend board meetings out of fear he would speak out.

"I was very vocal about that and I still am," Lochridge continued.

Titan sub inquiry - everything we know from the investigation so far

A public hearing into the five deaths of the people onboard OceanGate's ill-fated Titan submersible began on Monday (16 September).

It is expected to last two weeks.

Titan was 'unregistered, non-certificated and unclassed'

The first day of the hearing (16 September) heard how the submersible was built in 2020 and was 'unregistered, non-certificated and unclassed', as well as having no identification number.

The submersible's hull was never subject to third-party checks and officials said it was left exposed to the elements while in storage for seven months in 2022 and 2023.

Parts of Titan 'bonded together using an adhesive'

In 2017, the year OceanGate announced it would be conducting trips to the Titanic, employees bonded together the submersible's carbon fibre hull and titanium rings 'using an adhesive'.

Titan found 'partially sunk' month before tragedy

During its 2023 expedition, the Titan was found 'partially sunk' in the ocean.

Titan lost contact with support ship

Those onboard the Titan were communicating with support staff on the Polar Prince ship by text messages.

After a number of exchanges, Titan crew lost contact with Polar Prince as it descended.

One of Titan’s final responses was revealed to be: "All good here."

Titan 'struck by lightning'

Tony Nissen, OceanGate Expeditions’ former engineering director, testified that the Titan was hit by lightning during a test mission in 2018.

Nissen, who was allegedly fired in 2019 after not letting the submersible go to the Titanic, told OceanGate CEO Stockton Rush it was 'not working like we thought it would'.

When asked to pilot the submersible, Nissen said: “I’m not getting in it.”

Titan engineer 'felt pressure to get submersible ready for wreck dive'

When asked if there was pressure to get the Titan into the water, Nissen replied: “100%.”

Waivers

While Bonnie Carl, OceanGate's former human resources and finance director, said she was aware of a waiver people had to sign, she testified she 'never saw anyone sign anything'.

"When I was taking money, we hadn't even finished building the Titan," Carl claimed.

'No red flags' on day Titan went missing

Former OceanGate contractor Tym Catterson said: "There were no red flags... it was a good day."

Footage of Titan wreckage released by US Coast Guard

New, unseen footage of the doomed Titan sub has been released to the public by the US Coast Guard, with the camera panning around to see the tail cone of the sub on the ocean floor.

Whistleblower says implosion was 'inevitable'

Former employee of OceanGate David Lochridge gave evidence on Tuesday (17 September) and revealed how he warned of potential safety problems with the vessel as far back as 2018, which he says were ignored.

Lochridge, who was fired from the company in 2018, told investigators that it was 'inevitable' something would eventually go wrong, and when asked if he had any confidence in the way Titan was being built, he stated: "No confidence whatsoever, and I was very vocal about that, and still am."

"A lot of steps along the way were missed," Lochridge added. "I knew that hull would fail. It's an absolute mess."

He also criticised the 'arrogance' within the company, along with the 'control freak' tendencies of Stockton Rush.
