Search for Missing Titanic Submarine Intensifies with New Leads

The search for the missing submersible that was on an expedition to the site of the Titanic wreckage continues in the Atlantic Ocean. Planes detected potential signs of life in the search area, and the operations were relocated to explore the origin of the noises. The search area has now expanded to two times the size of Connecticut, and two remotely operated underwater vehicles are actively searching below the surface. The submersible had as much as 96 hours of oxygen when it began the expedition on Sunday morning, and the crew of the Canadian research vessel Polar Prince lost contact with the submersible about 1 hour and 45 minutes into the dive.
