Another Sub Mission To Search For Malaysian Plane
PERTH, Australia (AP) — A U.S. Navy robotic submarine is on its fifth mission to map the ocean floor, where officials believe a missing Malaysia Airlines plane and its black boxes could be located.
But officials say they've found no evidence yet.
As the sub searches a section of the Indian Ocean bottom, 11 planes and 12 ships continue the surface search across some 20,000 square miles of ocean.
