The US Coast Guard has confirmed an aircraft involved in the search for a missing submersible in the North Atlantic has detected underwater noises in the search area.
Several US media outlets are reporting sonar detected banging in 30 minute intervals, sighting an internal government memo, during the search for the submersible which was on a trip to see the wreckage of the Titanic.
On its official twitter page, US Coast Guard Northeast said some operations were relocated to try to find the noises, however nothing has been discovered so far. The information is also being analysed by the US Navy.
