Rescue teams expanded their search underwater on June 20, 2023, as they raced against time to find a Titan deep-diving tourist submersible that went missing near the wreck of the Titanic with five people on board and limited oxygen. All communication was lost with the 21-foot (6.5-meter) Titan craft during a descent June 18 to the Titanic, which sits at a depth of crushing pressure more than two miles (nearly four kilometers) below the surface of the North Atlantic.
