OceanGate, the company that runs the Titan submarine, thinks that the five people who were on board when it went missing are dead.

In a statement, the company called the five guys “real explorers with a strong sense of adventure.”

The Coast Guard said that a field of wreckage was found Thursday morning near where the Titanic sank.

On Sunday, the ship was no longer seen.

On board the sub were CEO of OceanGate Stockton Rush, 61, British-Pakistani businessman Shahzada Dawood, 48, and his 19-year-old son Suleman, as well as British investor Hamish Harding, 58.

Paul-Henry Nargeolet, a 77-year-old former French navy diver and famous expert, was the fifth person on board.

At a news conference on Thursday, US Coast Guard Rear Adm. John Mauger said that the pieces of debris seem to be from the Titan submarine.

It is not clear what happened to the Titan that caused it to break up.

When the ship went missing, forces from the US, Canada, Britain, and France joined together to look for it.

OceanGate said in a statement that it is grateful for “their dedication to finding these five explorers and their tireless work day and night to help our crew and their families.”
