‘Hope’: Banging sounds heard in missing OceanGate Titan submersible search at Titanic site | #HeyJB

A Canadian military surveillance aircraft detected underwater noises as a massive search continued early Wednesday in a remote part of the North Atlantic for a submersible that vanished while taking five people down to the wreck of the Titanic.

A statement from the U.S. Coast Guard did not elaborate on what rescuers believed the noises could be, though it offered a glimmer of hope for those lost abroad the Titan as estimates suggest as little as a day’s worth of oxygen could be left if the vessel is still functioning.

Meanwhile, questions remain about how teams could reach the lost submersible, which could be as deep as about 12,500 feet (3,800 meters) below the surface near the watery tomb of the historic ocean liner. Newly uncovered allegations also suggest there had been significant warnings made about vessel safety during its development.
