MH370 Search Area Narrows As More Signals Identified

AT SEA - APRIL 11: A Royal New Zealand Air Force P-3 Orion flown by (far left) Flt Lt Tim McAlevey takes part in the search to locate missing Malaysia Airways Flight MH370 at sea over the Indian Ocean on April 11, 2014 off the coast of Western Australia. Search and rescue officials in Australia are confident they know the approximate position of the black box recorders from missing Malaysia Airlines Flight MH370, Australian Prime Minister Tony Abbott said on Friday. At the same time, however, the head of the agency coordinating the search said that the latest "ping" signal, which was captured by a listening device buoy on Thursday, was not related to the plane.
