#BREAKING: Missing Titanic Submersible Update in Coast Guard Press Conference | #HeyJB Live

Rescuers in a remote area of the Atlantic Ocean raced against time early Tuesday to find a missing submersible carrying five people on a mission to document the wreckage of the Titanic.

The carbon-fiber 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 a Titanic expert. 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.
