Canadian aircraft has detected underwater noises in search for missing sub near Titanic

The US Coast Guard says a Canadian aircraft has detected underwater noises during search for a submersible that vanished while taking five people down to the wreck of the Titanic. As a result of the noises detected by the Canadian P-3 aircraft, search efforts have been relocated. Those searches had not found anything but are continuing. In addition to an international array of ships and planes, an underwater robot had started searching in the vicinity of the Titanic and there was a push to get salvage equipment to the scene in case the sub is found.
