Still No Malaysia Airlines Jet

An unmanned Navy sub has finished its month-long search for the missing Malaysia Airlines jet in the southern Indian Ocean. The Bluefin 21 has found nothing after scouring 330 square miles, based on acoustic signals. A Navy spokesman says the service and its international partners are trying to better understand that data now. They are suspending the underwater search for a few months until more powerful sonar equipment arrives. It will search a much wider area -- 21,000 square miles -- based on an analysis of satellite data indicating the plane's most likely course. The jet vanished on March 8.
