Flight 370: New search area and a new submarine joins the search

There is no sign of Flight 370 and there is no sign of the search slowing down. Planes and ships are now looking in a new area of the Indian Ocean closer to the Australian coast. This comes as the transcripts between the plane and air traffic control were just released. Jim Sciutto has the latest.

A nuclear submarine from the UK is joining the Flight 370 search with some powerful new tools. Kyung Lah has more from Australia.
