PERTH, Australia - Searchers engaged in a race against time to pinpoint "pings" from the missing Malaysian airliner's black boxes on Thursday detected a possible fifth signal, fuelling hopes that wreckage will soon be found.
The beacons on flight MH370's data and cockpit voice recorders are due to fade, more than a month after the Boeing 777 vanished. So the Australian-led search is vying to determine an exact location before sending down a submersible to plumb the Indian Ocean depths.
The Perth-based Joint Agency Coordination Centre (JACC) said the latest ping was detected Thursday afternoon by an Australian air force P-3C Orion surveillance plane, which has been dropping dozens of sonar buoys into the remote waters of the search zone.
"The acoustic data will require further analysis overnight but shows potential of being from a made-made source," JACC chief Angus Houston said in a statement.
