Investigators were analyzing data collected by a robotic submarine that completed its first successful scan of the seabed Thursday in the hunt for the missing Malaysian plane, but say tests have ruled out that a nearby oil slick came from the aircraft.
The unmanned sub's first two missions were cut short by technical problems and deep water, but the Bluefin 21 finally managed to complete a full 16-hour scan of the silt-covered seabed far off Australia's west coast, the search coordination center said. While data collected during the mission, which ended overnight, were still being analyzed, nothing of note had yet been discovered, the center said. The sub has now covered 90 square kilometers (35 square miles) of seafloor. (AP)
