“This marine casualty and the loss of five lives was preventable,” said Jason Neubauer, chairman of the U.S. Coast Guard Marine Board of Investigation charged with probing the Titan disaster.

The implosion of the OceanGate's submersible Titan in 2023 was "preventable," because of its inadequate design and "toxic" workplace culture, a report said.

The 2023 implosion killed five people on a dive to the wreckage of the Titanic, prompting a sprawling search of the north Atlantic Ocean.
