Tourist Company Says Submersible On Expedition To Titanic Wreck Site Went Missing

OceanGate Expeditions, a US firm deploying submersibles for deep sea expeditions, said in a statement on Monday that it is trying to re-establish contact with one of its vessels that went missing during an expedition to the wreckage site of the Titanic.

"Our entire focus is on the crewmembers in the submersible and their families," OceanGate said in a statement to CBS news.

The company stressed that it was "deeply thankful for the extensive assistance we have received from several government agencies and deep sea companies in our efforts to reestablish contact with the submersible."

The firm did not reveal in its statement how many people were on board the vessel and whether there were any tourists there.

The Boston Coastguard has said that it is undertaking an operation to locate a tourist submarine with an unknown number of people on board for an expedition to view the Titanic wreck after the vessel went missing in the Atlantic Ocean, BBC reported earlier on Monday.
