SYDNEY — A sensor dropped into the sea by a Royal Australian Air Force plane detected a possible acoustic signal in the same area of the Indian Ocean where a search ship had earlier detected signals that might have come from flight recorders from the missing Malaysia Airlines aircraft, Australian authorities overseeing the search said Thursday.
The announcement of the latest potential clue as to the whereabouts of the aircraft contained few details, and the signal could turn out to be another of the many false leads that have dogged the hunt for Flight 370 for more than a month. But it came in the same seas off Western Australia where the Ocean Shield, an Australian defense force ship, had already collected four sets of signals — two on Saturday, two on Tuesday — that could have come from beacons attached to the plane’s two flight recorders.
