The search in the Atlantic for a submarine that disappeared with five people on board near the wreckage of the Titanic, US media and AFP reported on Tuesday.

According to Rolling Stone magazine, the Canadian P8 plane “heard rumbles in the area at 30-minute intervals. Four hours later, additional sonar was deployed and shots were still being heard.”

CNN, citing an internal US government document, also reported the explosions without specifying when they were discovered.

Search authorities released an update Tuesday evening saying more sounds were heard, but they were not described as banging. However, it indicates “continued hope” that survivors will be found, the update said.

A renowned oceanographer said on Tuesday he was “getting hopeful” after rumblings were heard during the search for the missing Titan submersible and that teams do not need to wait to “deliver equipment”.

“I expect they spent a lot of time and a lot of resources trying to figure out where the bangs came from,” said David Gallo, RMS Titanic Inc.’s senior advisor for strategic initiatives.

“Time is of the essence because once … you have an area where you know the strike is coming from … you have to send resources there – submarines and robots – over that location to investigate,” he added, CNN reports. .

The five on board had less than 30 hours of oxygen left

The US Coast Guard said around 1 p.m. ET on Tuesday that the five people on board had less than 40 hours left to breathe.

The race against time is on to find the small submarine “Titan” that disappeared while taking tourists to the wreck of the Titanic. However, there are many unknown and difficult tasks in this mission to rescue five people aboard a submarine.

On Tuesday evening, the US Coast Guard announced that it had begun a remotely operated vehicle (ROV) dive to the last known location of the submarine.

France also announced on Tuesday that it would send a research vessel, L’Atalante, equipped with a robot capable of deep submersion, to help in the search and rescue operation for the people aboard the Titan. The ship, named Atalante, is operated by the Ifremer Research Institute. Ifremer said the U.S. Navy reached out to her on Monday asking for help.

U.S. and Canadian ships and aircraft swooped into the area 1,450 km east of Cape Cod, some of them launching sonar beacons that can observe at depths of up to 3,962 meters, Rear Admiral John Mauger of the US Coast Guard told reporters on Monday. .
