One year after the tragedy, officials are no closer to finding answers. One year ago, Malaysia Airlines Flight 370 disappeared as it made its way from Kuala Lumpur to Beijing. The one-year anniversary is a difficult time for many victims’ families. The search for the Boeing 777, with 239 passengers and crew on board, has covered almost 1.8 million square miles of the southern Indian Ocean, and has involved 82 aircraft and 84 ships from 26 countries. If the massive undersea search for Malaysia Airlines Flight 370 turns up nothing by the end of May, the countries leading the effort will close the operations.
