Missing Submarine

Rescue crews searching for a submersible with five people aboard that went missing while touring the Titanic’s wreckage are keeping a nervous eye on the craft’s dwindling oxygen supply as they navigate choppy waters and low visibility in a remote area of the North Atlantic Ocean.

The Coast Guard and the Royal Canadian Air Force are deploying more aircraft and vessels to aid in the search for the 21-foot vessel, which began its descent to the bottom of the ocean on Sunday morning – and has just four days of emergency capability.

Searchers are taking the mission below sea level after scouring an area of the ocean’s surface about the size of Connecticut, US Coast Guard District 1 Rear Admiral John Mauger said Tuesday morning. “We now have underwater search capability on scene, and so we’re going to be using that to see if we can locate the submersible in the water,”
