More than a decade later, the disappearance of Malaysia Airlines Flight MH370 remains one of the greatest mysteries in aviation history. In this video we break down 10 things we still do not know about MH370 and 10 confirmed pieces of evidence that investigators have uncovered. The plane vanished in March 2014 with 239 people on board after suddenly deviating from its flight path and disappearing from radar. Satellite data later suggested the aircraft continued flying for hours before likely crashing somewhere in the southern Indian Ocean, far from its intended route. Investigators have confirmed several pieces of debris washed ashore in the Indian Ocean, proving the plane ended in the sea, but the main wreckage has never been found. Despite massive search efforts and new missions still being launched, key questions remain unanswered. What really happened onboard, who was responsible, and where exactly the aircraft lies are still unknown. Comment below with what you think happened to MH370.
