PERTH, Australia (AP) - Crews searching for the missing Malaysia Airlines jetliner have just a few days left before pings from the plane's two data recorders could stop transmitting.
A black box's batteries last about a month after a plane crash.
Today two ships with sophisticated equipment began searching underwater in a remote stretch of the Indian Ocean.
One ship has a pinger locator from the U.S. Navy.
