malaysia_airlines_plane_missing_mgnWhat happened to Malaysia Airlines Flight 370 at the weekend was exceptionally rare, but it has happened before. The Boeing 777 passenger jet vanished just two hours into a flight from Kuala Lumpur on its way to Beijing. There was no distress call and now grave fears are held for the crew and 239 people on board, including six Australians.  It often takes time for investigators to get to the bottom of aviation disasters. In 2009, it took five days for search and rescue teams to find Air France Flight 447 from Rio de Janeiro to Paris after the Airbus A330 plunged into the Atlantic Ocean, killing all 228 on board. It took another three years for investigators to report that ice crystals had most likely blocked the plane’s air speed sensors, eventually leading to the plane to stall.
