The crew of the Titan submersible that imploded in June 2023 on its way to visit the wreck of the Titanic texted “all good here” prior to the accident.

The texts were shown during a hearing held by the Coast Guard’s Marine Board of Investigation on the Titan, which also showed animated images of the Titan sub. It said the implosion happened about 30 minutes after the “all good here” text.

Five people were killed as a result of the implosion of the Titan last year.

OceanGate, the company behind the Titan submersible, later suspended its expeditions and was hit with a lawsuit in August from the estate of one of the passengers, Paul-Henri Nargeolet.

“I think it’s telling that even though the University of Washington and Boeing had key roles in the design of previous but similar versions of the Titan, both have recently disclaimed any involvement at all in the submersible model that imploded,” Tony Buzbee, a lawyer for the plaintiffs, said in a statement.
