Race is on to find #MH370 Malaysia airliner’s black boxes

Time is running out to find the crucial keys that could solve the mystery of how and why Malaysia Airlines Flight 370 went down.
After the excruciating 17-day wait for confirmation that the Boeing 777 crashed into the southern Indian Ocean, searchers are racing to locate the so-called black boxes before a battery-powered ping they emit fades away.
By law, the boxes with must be able to send those signals for at least 30 days following a crash. But experts say they can continue making noise for another 15 days or so beyond that, depending upon the strength of the black box battery at the time of the crash.
Without the black boxes — the common name for the voice and data recorders normally attached to a fuselage — it would be virtually impossible for investigators to definitively say what caused the crash.
