Titan submersible hearing live: Mission specialist breaks down

“All good here” were some of the final words that the doomed Titan submersible crew communicated before the submersible imploded on its mission to the Titanic wreckage site in June 2023.

The message, revealed as part of the Coast Guard’s Monday hearing into the circumstances of the failed mission, was sent to support vessel Polar Prince on June 18, 2023, shortly before the submersible imploded, killing all five of its crew members. It was an incident that captivated both sides of the Atlantic as crews made a mad dash to save the crew after the sub lost contact with the surface – with the world unaware that the lives had been lost.

The Coast Guard played an animated re-enactment of the Titan’s voyage that captured the submersible’s final, spotty exchange with the Polar Prince, during the Monday hearing that shed new light on the sub’s final mission.

Around 10am on June 18, Polar Prince asked the Titan crew whether they were able to see the support vessel on the submersible’s display. The support vessel asked the crew the same question seven times over the course of seven minutes. The Titan crew then sent “k,” meaning it was asking for a communications check.

He said that he and Stockton Rush “pretty much stopped talking to me rationally” after the Andrea Doria incident.

At the end of the summer 2016, Rush and others told him OceanGate was “no longer willing to pay” for his wife and daughter’s permanent residence. Lochridge believed it was because he “embarrassed him in front of clients,” referring to the Andrea Doria crash, which was a “turning point” in his and Rush’s relationship.

The following day, Rush presented him with a new contract that he sign a new contract that stipulated he would have to reimburse the company if he left within the next 12 months. Rush instructed him not to tell his immigration attorney about the new arrangement.

“I had my doubts,” Catterson said about the carbon fiber hull.

“I think that when you put it under compression, they can buckle, they can shift, they can move all these directions three-directionally,” he added.

When aksed if he had voiced his concerns about the hull to any OceanGate employees, Catterson said he told Stockton Rush, Tony Nissen, the first witness today who is an engineer, and David Lochridge, who was terminated shortly after detailing his concerns with the Titan’s design in an inspection report.

The US Coast Guard’s hearing on the Titanic submersible tragedy has concluded for the day and will resume at 8.30am on Friday.

Steven Ross says that he once asked Stockton Rush how long the Titan would be good for until it needed refurbishments. Typically, subs need to be refurbished after a certain number of dives because of the pressures at deep levels.

But, Rush told Ross he thought his design would be good for “indefinite” trips to the Titanic wreckage.

Testimony from the former scientific director is vague. He is avoiding giving direct answers to questions presented to him by the panel.
