A former OceanGate scientific director said the Titan submersible suffered a malfunction six days before imploding in June 2023, killing all five people on board.

The U.S. Coast Guard has released the first photo of the doomed OceanGate Titan submersible. The vessel had been on an expedition to tour the wreckage of the Titanic when it imploded shortly after losing contact with its support ship last June.

A hearing began amid an ongoing review of the implosion of the submersible as it sought to uncover wreckage of the Titanic, which sank in 1912.

OceanGate's Titan sub briefly became tangled up in the Titanic during a 2022 dive, according to a mission specialist who was on the dive.

A paid passenger on an expedition to the Titanic with the company that owned the Titan submersible testified before a U.S. Coast Guard investigatory panel Friday that the mission he took part in was aborted due to an apparent mechanical failure.

Another mission specialist who worked with the company that owned the Titan submersible that imploded last year while on its way to the Titanic wreckage is scheduled to testify before a U.S. Coast

The malfunction caused passengers onboard the submersible to “tumble about,” Steven Ross said, and it took an hour to get them out of the water.

Former passenger Fred Hagen said the 'Titan' — which imploded and left five people dead in June 2023 — was "an experimental vessel [and] it was clear that it was dangerous"
