Planes, ships and two submersible sound locators were deployed Saturday to again scour a remote patch of the Indian Ocean in the increasingly urgent hunt for the Malaysia Airlines Flight MH370 that vanished four weeks ago.
A multinational team is desperately trying to find debris floating in the water or faint sound signals from the plane's flight recorders that could lead them to the aircraft and help unravel the mystery of its fate.
Beacons in the black boxes emit ''pings'' so they can be more easily found, but the batteries only last about a month. And officials say that the more time that passes before any floating wreckage is found, the harder it will be to find the plane itself.
So far, there's been no sign of the Boeing 777.
