Authorities have confirmed that a deep-sea submersible, transporting a crew of five individuals on an expedition to explore the century-old remains of the Titanic wreck, has imploded, killing all five persons on board.
This puts an end to a multinational five-day search for the vessel.
The Titan, operated by the U.S.-based company OceanGate Expeditions, had been missing since it lost contact with its surface support ship on Sunday morning about an hour, 45 minutes into what should have been a two-hour dive to the world's most famous shipwreck.
Five major fragments of the 22-foot (6.7-meter) Titan were located in the debris field left from its disintegration, including the vessel's tail cone and two sections of the pressure hull, Coast Guard officials said. No mention was made of whether human remains were sighted.
U.S. Coast Guard Rear Admiral John Mauger told reporters "The debris field here is consistent with a catastrophic implosion of the vehicle,"
Even before the Coast Guard's press conference, OceanGate issued a statement saying there were no survivors among the five men aboard the Titan, including the company's founder and chief executive officer, Stockton Rush, who was piloting the Titan.
The four others were British billionaire and explorer Hamish Harding, 58; Pakistani-born businessman Shahzada Dawood, 48, and his 19-year-old son, Suleman, both British citizens; and French oceanographer and renowned Titanic expert Paul-Henri Nargeolet, 77, who had visited the wreck dozens of times.
