Mystery of flight MH370: Did the pilot chart a course into the Indian Ocean?

It has now been over two years of theories, false leads, heartbreak, and investigation since the Malaysian Airlines flight 370 mysteriously vanished off the radar during a routine flight from Kuala Lumpur to Beijing with 239 passengers and crew aboard. The March 2014 disappearance kicked off a multinational search effort, which initially ranged from China southward toward Australia. As the hope of finding survivors waned, the importance of locating the aircraft and finding answers to what, or who, was responsible for the disappearance waxed.
