U.S. and Canadian ships and planes are currently searching for a submarine that disappeared off the coast of southeastern Canada more than a day earlier when passengers were taking tourists to explore the wreck of the Titanic, officials said.
The U.S. Coast Guard said there was one pilot and four passengers on board and that the ship was able to stay underwater for 96 hours, but it was unclear whether it was still underwater or surfaced and unable to communicate.
U.S. and Canadian ships and planes have swarmed the area about 900 miles (1,450 km) east of Cape Cod, some dropping sonar buoys that can monitor to a depth of 13,000 feet (3,962 meters), U.S. Coast Guard Rear Admiral John Mauger told reporters on Monday.
It is a remote area and it is a challenge to conduct a search in that remote area,” Mauger said.
“We are deploying all available assets to make sure that we can locate the craft and rescue the people on board,” he said. “Going into this evening we will continue to fly aircraft and move additional vessels.”
OceanGate Expeditions, the private company that operates the submarine, said in a statement Monday that it was “mobilizing all options” to rescue those on board.
British billionaire Hamish Harding is among the passengers, according to a post by a relative on social media. Pakistani businessman Shahzada Dawood and his son Suleman were also on board, their family said in a statement.
“We are very grateful for the concern of our colleagues and friends and ask everyone to pray for their safety,” the statement said.
