Debris from OceanGate sub found 1,600 feet from Titanic, 5 presumed dead
Five people who were on a sub that went missing during a voyage to the wreckage of the Titanic did not survive, the company that planned the trip said Thursday, as the U.S. Coast Guard said the OceanGate vessel experienced a "catastrophic loss of the pressure chamber," and confirmed that the debris found on the sea floor were pieces of the missing sub.
