The fate of five people onboard a missing submersible which was bound for the Titanic wreckage has been on the minds of those visiting Titanic Belfast on Tuesday.
A major search and rescue operation being led by the US Coast Guard and involving military aircraft is under way after the submarine went missing on Sunday evening about 435 miles south of St John’s, Newfoundland.
The search teams are engaged in a race against time as they are believed to have roughly four days of oxygen left, according to the US Coast Guard.
