A Chinese Air Force plane arrives at Perth International Airport in Australia, March 22, 2014. Two Ilyushin Il-76 aircraft from the Chinese Air Force left Malaysia on Saturday for Australia to join the search in the southern Indian Ocean. With Australian and New Zealand airforce P3 Orions limited by the vast distances and their dependence on infrared imaging, the Chinese IL-76 will be a welcome relief to the authorities here as the challenges of the task at hand begin to overwhelm available resources.
