News conference on disappearance of Flight MH370 on Thursday

Australian officials are set to hold a news conference on the search of missing Malaysia Airlines flight MH370 on Thursday. The search for the plane has involved more than two dozen countries contributing planes, ships, submarines and satellites. An initial hunt along a rugged 60,000-sq km patch of sea floor off the coast of Perth had yielded no sign of the plane. The search was later extended to another 60,000 sq km, covering 95 percent of MH370's flight path. The find renewed hope that the aircraft might be found and questions surrounding the crash might be answered, but a lot remains unknown and relatives remain desperate for answers.
