A submarine used to take tourists to a wreck of the Titanic has been reported missing in the Atlantic Ocean.
A search and rescue mission is currently underway to trace the vessel, the BBC reports. Whether anybody was on-board the submarine at the time of its disappearance is currently unknown.
Those wishing to visit the wreck of the Titanic, which sunk in 1912, can do so by paying for small trips in submarines. Last year, it was reported that one such excursion cost a group of guests $250,000 to take the submersible 2.4 miles down to where the wreckage lays on the seabed.
