Coast Guard to lead transnational investigation into Titan implosion accountability

A transnational inquiry has been launched to determine accountability for the deaths of five passengers aboard the OceanGate Expeditions submersible that imploded during a descent to the wreckage of the Titanic in the North Atlantic, the United States Coast Guard announced Sunday. Maritime agencies from Canada, France and Britain are joining an investigation that will be led by the Coast Guard, Capt. Jason Neubauer said during a news conference at Coast Guard Base Boston. Neubauer said the priority of the investigation, known as a Marine Board of Investigation, or MBI, "is to recover items from the seafloor." Neubauer said investigators will also determine "the cause of this marine casualty" and establish accountability.
