The Malaysian Airlines plane MH 370 is not the first disappearing without trace. Even if it is, this is highly unusual. In 2009, an Air France airbus jet also vanished of radar screen. Wreckage from the lost aircraft were eventually found in the Atlantic yet the causes of the crash remained mystery until voice and data recorders were found years later. The final report said human error was partly blamed. ‘Today aircrafts are incredibly reliable and you do not get some sudden structure failure in a flight’, said Mr. Louis, an aviation expert in New York said. ‘It just doesn’t happen. It just won’t happen’, he added. Boeing describes its 777 model a super star. First flown in 1995, more than a thousand planes now rolled up the production line. It can travel for 16 hours non-stop and experts point to its impressive safe record with one fatal crash in 5 million flights. It could take investigators months if years to determine what exactly happened to the Malaysian aircraft but experts believe what happened was quick and left the pilot no time to put a distress call.
