AirAsia Black-Box Search Restarts Debate on Tracking Technology

An international search team has yet to find the black boxes that hold clues to what brought down AirAsia Bhd. Flight 8501 almost a week ago, sparking renewed calls to speed use of technology that would make tracking planes and studying accidents easier.

The hunt under way near Pangkalan Bun, about 600 miles (1,000 kilometers) southeast of Singapore includes ships sent by Malaysia and Singapore equipped with underwater sonar and French experts to help retrieve the voice and data recorders. The plane crashed in the Java Sea Dec. 28 with 162 people on board. As of Jan. 2, 30 bodies had been recovered along with parts of the plane.
