MH370 Black Box Losing Power

    Royal New Zealand Air Force (RNZAF) captain, Wing Commander Rob Shearer, looks out from the cockpit of a P3 Orion maritime search aircraft while flying over the southern Indian Ocean looking for missing Malaysian Airlines flight MH370 March 31, 2014. Australian Prime Minister Tony Abbott said on Monday the hunt for Malaysia Airlines Flight MH370 had no time limit, despite the failure of an international operation to find any sign of the plane in three weeks of fruitless searching. A total of 20 aircraft and ships were again scouring a massive area in the Indian Ocean some 2,000 km (1,200 miles) west of Perth, where investigators believe the Boeing 777 carrying 239 people came down.

    Missing Malaysia Airlines Flight 370's black box will run out of power by Monday. The race against time has increased the urgency of the hunt to locate signals from the data recorder, but with no debris discovered yet, the job has become exceedingly difficult. British and Australian ships are using submerged pinger locaters to locate the data recorder's signal, and an unmanned submarine is also waiting in the wings. “The area of highest probability as to where the aircraft might have entered the water is the area where the underwater search will commence,” said former Australian defense force chief Angus Houston, who is in charge of coordinating efforts.
