A former passenger on the missing Oceangate craft has described the deep-diving vessel's voyage to the Titanic as a "suicide mission".
The vessel, named Titan, lost communication with tour operators on Sunday about 435 miles south of St John's, Newfoundland, during a voyage to the famous shipwreck off the coast of Canada.
German adventurer Arthur Loibl, who previously explored the Titanic wreckage on the same submersible, spoke of the problems experienced on the mission and said he was fortunate to survive.
