New footage has shown the doomed Titan sub’s tail cone resting on the ocean floor after it imploded last June.

A hearing about the deaths of those on the doomed submersible opened this week in Charleston, South Carolina, and is expected to last two weeks.

The video was released by the US Coast Guard, and shows the wreckage resting on the deep ocean floor.

It comes as this week, David Lochridge, OceanGate’s former operations director, said he hoped OSHA had investigated the concerns he had about the sub before the disaster.

He said: ‘I believe that if OSHA had attempted to investigate the seriousness of the concerns I raised on multiple occasions, this tragedy may have been prevented.’

British adventurer Hamish Harding, father and son Shahzada and Suleman Dawood were killed on board in June 2023, alongside French national Paul-Henri Nargeolet and OceanGate Expeditions CEO Stockton Rush.

The discovery of the tail cone sitting on the sea floor led to the confirmation of the ‘catastrophic loss’ of the Titan sub and the death of all five members on board.

At the hearing, the US coast guard presented a visual re-creation of the journey of the Titan before it imploded.

One of Titan’s final responses, which became spotty as it descended, was ‘all good here’.

According to this presentation, the crew communicated with support staff aboard the Polar Prince by text messages.

But they lost contact after repeated inquiries from the Polar Prince about the submersible’s depth and weight as it descended.

The Polar Prince sent repeated messages asking if the Titan could still see the ship on its onboard display.

Mystery behind ‘banging noises’ remains unanswered

As rescuers frantically searched for the vessel, sonar buoys detected what sounded like ‘banging noises’.

This led to hopes the crew on board were still alive.

Tym Catterson told the hearing: ‘If it happens more than once or it happens consistently, it’s something that humans are doing.’

Search teams rushed to where the sounds were coming from as there were ‘theories flying around from people totally without sleep and very anxious’.

But it is still not known what the cause of the banging noises are.
