Faint hope as noise detected in search for sub near Titanic wreck, time running out

HALIFAX — There is a glimmer of hope in the search for a submersible missing near the wreck of the Titanic in the Atlantic Ocean south of Newfoundland after an underwater noise was detected overnight.

The U.S. Coast Guard says a Canadian military patrol plane picked up the sound, but adds that it’s unclear what that may indicate.

In a tweet, the coast guard says three vessels arrived at the scene today, including the Canadian Coast Guard Ship John Cabot, which has side-scanning sonar. 

Time is running out for the five people on board the Titan, with less than a day’s worth of air supply estimated to be on the 6.4-metre vessel.
