Military officer Ngo Ngoc Dong is seen reflected in a map on an iPad showing the path of the Vietnam Air Force search and rescue AN-26 aircraft that he is travelling on, during a mission to find Malaysia Airlines flight MH370 that disappeared from radar screens in the early hours of Saturday, off Con Dao island March 12, 2014. The search for the missing Malaysia Airlines Boeing 777 jetliner expanded on Wednesday to cover an area stretching from China to the Andaman Sea, with authorities no closer to explaining what happened to the plane or the 239 people on board. Vietnam briefly scaled down search operations in waters off its southern coast, saying it was receiving scanty and confusing information from Malaysia over where the aircraft may have headed after it lost contact with air traffic control.
