'Safety is relative': What CEO of missing Titanic submarine company told me during my trip

Interview with David Pogue, CBS correspondent who rode on the submersible that takes passengers to the Titanic, which is now missing. A Canadian military surveillance aircraft detected underwater noises as a massive operation searched early Wednesday in a remote part of the North Atlantic for a submersible that vanished while taking five people down to the wreck of the Titanic. A statement from the U.S. Coast Guard did not elaborate on what rescuers believed the noises could be, though it offered a glimmer of hope for those lost aboard the Titan as estimates suggest as little as a day's worth of oxygen could be left if the vessel is still functioning. #dailymail #titanic #submersible #oceangate Daily Mail Homepage: https://www.dailymail.co.uk/ Daily Mail Facebook:   / dailymail   Daily Mail IG:   / dailymail   Daily Mail Snap:   / 8392137033   Daily Mail Twitter:   / mailonline   Daily Mail Pinterest: https://pinterest.co.uk/dailymail Get the free Daily Mail mobile app: https://dailymail.co.uk/mobile
