Coast Guard confirms crew, passengers on submersible on Titanic voyage dead, 'catastrophic event'

U.S. Coast Coast Rear Admiral Johh Mauger said Thursday the crew and passengers on the Titanic submersible are dead.

Officials said attributed their deaths to a "catastrophic event" or "implosion." 

The submersible had been missing since Monday. It went missing off the coast of Newfoundland. 

"This morning, an ROV or remote operated vehicle from the Vessel Horizon Arctic discovered the tail cone of the Titan submersible approximately 1600 feet from the bow of the Titanic on the seafloor," Mauger said at a press conference in Boston. 

"The ROV subsequently found additional debris in consultation with experts from within the unified command," he continued. "The debris is consistent with a catastrophic loss of the chamber pressure."

He then offered his condolences to the families of those lost. 

British businessman Shahzada Dawood, his son Suleman Dawood, British billionaire adventurer Hamish Harding, OceanGate CEO and founder Stockton Rush and French submersible pilot Paul-Henri Nargeolet were on the submersible.
