Search and Rescue Underway for Submersible Exploring Titanic Wreckage

A search and rescue operation is underway for a submersible carrying five people that went missing while touring the wreckage of the Titanic in the North Atlantic. The vessel has four days of emergency capability, and crews with the US and Canadian coast guards are using sonar to listen for sounds far below the water. The submersible was on an expedition to view the Titanic wreckage, and the company conducting the expedition, OceanGate Expeditions, is assisting in the search. Time is a factor, and officials are racing against the clock to locate the submersible and rescue those on board.
