Dr. David Gallo, a deep sea explorer, claimed in an interview with a British TV channel this morning that three distinct aircraft equipped with sensors heard recurring underwater noises for more than two days.The exact location and source of the sounds, according to a US Coast Guard official, haven't yet been established, but they do offer a chance to focus the search.

Estimates indicate that Titan's oxygen supply could run out as early as Thursday AM local time, despite the US Coast Guard's statement that authorities are still hopeful of saving people aboard.The CEO of the business leading the trip, pilot Stockton Rush, together with British explorer Hamish Harding, Pakistani father-and-son team Shahzada and Suleman Dawood, and Titanic specialist Paul-Henry Nargeolet are all believed to be lost aboard the ship.

A number of recently discovered allegations imply that the ship's safety had been the subject of serious warnings before it vanished.
