Submarine that went to see Titanic disappeared in the Atlantic, five people including billionaire are on board

A tourist submarine that went to see the wreckage of the Titanic went missing in the Atlantic Ocean on Sunday. It is being told that there was a pilot and four tourists in this submarine. British billionaire Hamish Harding is also included in these people. Here, as soon as the news of the sinking of the submarine spread, America and Canada started a search operation.
According to information, the tourist submarine landed in the Atlantic Ocean on Sunday. About two and a half hours after landing in the water, she lost contact and went missing. At the same time, there is very little time to find this submarine, as it only has 96 hours of oxygen.
Nothing has come to light so far in the search operation being run by the US and Canada. Rescue teams from both countries are continuously searching in the water. Sonar buoys have been sent into the water to search for the submarine so that they can monitor the water. At the same time, help is being sought from other ships as well.
It costs about two crore rupees to see the wreckage of the Titanic. This trip starts from Newfoundland in St. John's. The Titanic ship set sail on 10 April 1912 and sank after hitting an iceberg in the Atlantic Ocean on 14–15 April. More than 1500 people died in this. The wreckage of the Titanic was discovered in 1985.
