Investigative Report of the Disappearance of Flight MH370. The whereabouts of the plane is only one question still unanswered. The investigators are also considering: If the two pilots were involved in the disappearance, were they working together or alone, or with one or more of the passengers or crew? Did they fly the plane under duress or of their own will? Did one or more of the passengers manage to break into the cockpit or use the threat of violence to gain entry and then seize the plane? And what possible motive could there be for diverting the jet? Why don't we have any answers?
