Search continues for missing sub on Titanic wreckage tour

(AP) Rescuers in a remote area of the Atlantic Ocean raced against time early Tuesday to find a missing sub carrying five people on a mission to document the wreckage of the Titanic, the iconic ocean liner that sank more than a century ago.

The submersible named the Titan, part of a mission by OceanGate Expeditions, carried a pilot, a renowned British adventurer, two members of an iconic Pakistani business family and another passenger. Authorities reported the vessel overdue Sunday night about 435 miles (700 kilometers) south of St. John’s, Newfoundland, according to Canada's Joint Rescue Coordination Center.

Every passing minute, however, puts the Titan's crew at greater risk. The submersible had a 96-hour oxygen supply when it put to sea at roughly 6 a.m. Sunday, according to David Concannon, an adviser to OceanGate.

“It is a remote area — and it is a challenge to conduct a search in that remote area,” said Rear Adm. John Mauger, a commander for the U.S. Coast Guard, which also is searching for the Titan. “But we are deploying all available assets to make sure we can locate the craft and rescue the people on board.”
