Search For Flight 370 Continues

(Perth) -- Search teams from a half dozen countries are again hunting for the missing Malaysian jetliner. About ten planes and nine ships are covering a stretch of the southern Indian Ocean in a race against time. The airliner's black box recorder has an expected battery life of about 30 days, and experts say they will fail in the next few days. More than three weeks have passed since the jet vanished from radar en route from Kuala Lumpur to Beijing with more than 230 people on board.
