Titanic Submarine Search: ‘Banging sounds in the area every 30 minutes..."

A Canadian military surveillance plane today discovered underwater noises, according to reports in the international media, days after a submarine carrying five passengers to the undersea that disappeared while descending to the wreckage of the Titanic.

The news gives the rescue effort, which has been ongoing since Sunday, some hope. While this was going on, two media sources cited US Department of Homeland Security internal emails and government documents to claim that teams had been hearing "banging sounds in the area every 30 minutes."

On the other hand, this has not yet received formal confirmation. The US Coast Guard did not go into further detail regarding what the noises might be, according to the rescuers. If the undersea vessel, called "Titan," is still operating, estimates say there may only be enough oxygen for one day. The lost submersible, which could be as deep as 12,500 feet (3,800 meters) below the surface close to the iconic ocean liner's submerged grave, is still unaccounted for.

Stockton Rush, the CEO of the expedition-leading organization, a British adventurer, two members of a Pakistani business family, and a Titanic expert are among those still missing for within the submarine.

A Canadian P-3 Orion aircraft has discovered underwater noises in the specified search area, the Coast Guard said on Twitter. An underwater robot was then sent to the area to look into it. Sadly, despite being continuing, these searches have not yet yielded any fruitful results. According to the Coast Guard, the data gathered by the P-3 aircraft has been given to US Navy experts for additional study, which will be taken into account for upcoming search operations.
