Six months after the disappearance of Malaysia Airlines flight 370 it is still the subject of a slew of explanations. Why has this tragedy prompted such a wave of conspiracy theories? Sudden, dramatic events often provoke conspiracy theories – particularly where the official version is disbelieved. Think JFK, Princess Diana, 9/11. But in the case of MH370 there is not even an official version. Nobody knows what happened to MH370. It's a modern mystery.
