Tim Taylor: Oceanographer says finding the missing Titanic submersible is just the first step

There has been little sign of hope for the missing Titanic submersible that's caught the attention of the world. The sub with five onboard went missing off the south-eastern coast of Canada four days ago It's expected to run out of oxygen supply about 10 this evening. Searchers are concentrating their efforts on a remote area of the North Atlantic after reports of "noises". Oceanographer Tim Taylor told Mike Hosking finding them is just the first step. He says in 24 hours they still have to get them up and out of the Atlantic and unbolt them. Taylor says that will take hours. LISTEN ABOVESee omnystudio.com/listener for privacy information.
