'Banging' noises have been detected in the search for the missing submersible near the wreck of the Titanic.
The deep-sea vessel lost communication with tour operators on Sunday while about 435 miles south of St John’s, Newfoundland, during a voyage to the shipwreck off the coast of Canada. Titan has five people on board who now face a dwindling supply of oxygen, with the US Coast Guard estimating on Tuesday that the 6.7 metres (22ft) long OceanGate Expeditions vessel had just 40 hours left.
British billionaire adventurer Hamish Harding is on board, as well as Shahzada Dawood, his son Suleman and OceanGate’s chief executive and founder Stockton Rush, reportedly together with French submersible pilot Paul-Henry Nargeolet. The US Coast Guard on Wednesday morning said: "Canadian P-3 aircraft detected underwater noises in the search area.

"As a result, ROV (remote operating vehicles) operations were relocated in an attempt to explore the origin of the noises. Those ROV searches have yielded negative results but continue.
“Additionally, the data from the P-3 aircraft has been shared with our U.S. Navy experts for further analysis which will be considered in future search plans."
Meanwhile, US media outlet The Rolling Stone reported an internal US government memo said 'banging' was detected by Canadian search aircraft in 30-minute intervals on Wednesday. The Explorers’ Club, of which Mr Harding is a founding member, shared an upbeat message today.
President Richard Garriot de Cayeux said in a statement: "There is cause for hope, that based on data from the field, we understand that likely signs of life have been detected at the site. They precisely understand the experienced personnel and tech we can help deploy… We believe they are doing everything possible with all the resources they have."
Mr Garriot de Cayeux said they are ready to provide the UK-based Magellan’s remotely operated vehicle (ROV) that is certified to travel as deep as 6,000 metres. It is understood the King is being kept informed of the search efforts, as Shahzada Dawood is a long-time supporter of The Prince’s Trust International and The British Asian Trust, both of which are charities founded by Charles.
On Tuesday David Mearns, a deep-sea shipwreck hunter who is friends with Mr Harding and Mr Nargeolet, said he had seen reports of 'tapping' being heard in the water, which he said could indicate the passengers are alive.
He told Channel 4 News: "There’s some reports that I’ve just read from my own club, which is how I know Hamish, is that somebody today has heard some tapping. Now they’ve got sonar buoys out there, there may be some other hydrophones that the mothership the Polar Prince had in the water.
"It’s hard to imagine how they could have heard that but still, they are at least trying to operate or encourage the rescue efforts to continue on and to be redoubled on the fact that they’ve heard something which suggests that the men are alive in the submersible."
On Tuesday, Captain Jamie Frederick of the US Coast Guard said a 'unified command' of multiple agencies was formed on Monday to tackle the 'very complex problem' of finding the missing submersible.
