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.
