The Titanic tourist sub that was lost with five passengers aboard near the wreck of the famed liner likely imploded hours before a massive search and rescue was even launched, says the US Coast Guard.
OceanGate Expedition’s Titan submersible began its journey to the wreck site, which sits at a depth of 12,500ft at the bottom of the Atlantic Ocean, on Sunday morning. About an hour and 45 minutes later, the Titan lost contact with its surface ship, the Polar Prince.
