Divers retrieved one black box and located the other from the AirAsia plane that crashed more than two weeks ago, a key development that should help investigators unravel what caused the aircraft to plummet into the Java Sea. The two instruments, which emit signals from their beacons, are vital to understanding what brought Flight 8501 down on Dec. 28, killing all 162 people on board. They should provide essential information about the plane and all of the conversations between the captain and co-pilot for the duration of the flight.
