A Malaysia Airlines flight vanished without a trace while en route from Kuala Lumpur to Beijing on March 8. The weather was clear and there was no distress signal from the cockpit when the plane disappeared from radar screens. A massive search operation combed the Indian Ocean, but the Boeing 777 was never found.
After more than nine months, not a single piece of debris from MH370 has turned up. Despite numerous conspiracy theories, we still don’t know what happened to the plane. All 239 people on board are presumed dead.
