Underwater noises heard in search for missing Titanic sub
The US Coast Guard has confirmed that a Canadian P-3 aircraft detected “underwater noises” in a search for the missing Titanic sub.
US media, citing internal US government memos, described the noises as “banging sounds”. Experts say the sounds are difficult to interpret without seeing the data, but it’s possible they could be short, sharp, relatively high-frequency noises made by hitting the titanium end bell with another piece of metal or hard object within the pressure vessel.
On board, the sub are five people – including British-Pakistani businessman Shahzada Dawood and his son Suleman, along with British explorer Hamish Harding. Former French Navy Diver Paul-Henry Nargeolet and Stockton Rush, the chief executive of OceanGate – the firm behind the dive.
Contact with the miniature sub was lost on Sunday as it made a 3,800m descent to the wreck of the famous British ship, the Titanic.
The sub’s air supply is expected to run out on Thursday at around 11,000 BST.
The company behind the tourist trip to see the Titanic wreck – OceanGate, had been warned of safety problems in the sub in 2018, according to US court documents.
