MH370 Search Area Narrows As More Signals Identified

PERTH, AUSTRALIA - APRIL 12: A Chinese Ilyushin IL-76s aircraft comes in for a landing at Perth International Airport after returning from the on-going search operations for missing Malaysia Airlines Flight MH370 on April 12, 2014 in Perth, 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.
