A Canadian military surveillance aircraft detected underwater noises as a massive operation searched 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.

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.
