OceanGate's submersible, the Titan, has gone missing on a trip to the Titanic wreck site in the North Atlantic. Search and rescue teams are combing the area for the vessel, which is equipped with features that allow it to rise from the depths of the sea without electricity. David Pogue, a CBS News correspondent who was aboard the Titan last year, noted that the submersible did not have a beacon similar to an aircraft’s emergency locator transmitter, but that it had previously gotten “lost on the sea floor for a few hours” and still had communication with its mother ship. The cause of the disappearance is still unknown.
