(Reuters) - A friend of one of the passengers on board the submersible vessel that went missing on a trip to explore the wreckage of the Titanic said that "every single minute" felt like hours as time ticked away to find them alive.

Speaking from Svalbard in Norway on Tuesday, Jannicke Mikkelsen said she was not sleeping and just hoping for good news, as rescuers scoured thousands of square miles in the remote North Atlantic to find her friend Hamish Harding, 58, and four others.
