Rescue teams are searching for a British billionaire and four others who went missing on a deep-sea vessel near the wreck site of the Titanic ocean liner.
The US Coast Guard is leading the search for the small craft, named Titan, which was reported overdue about 435 miles south of St John's in Newfoundland, Canada, on Sunday evening. British billionaire Hamish Harding, chairman of private plane firm Action Aviation, has been named as one of the people on board.
The Titan's dive on Sunday is one of many that have been made to the wreck, which is about 2.4 miles below the surface, by OceanGate Expeditions since 2021.
