They’ll find an honest Hillary before they find that plane.
A scenario that fits all the circumstances would be that one of the two pilots had a terrorist plot, he started to carry it out, but the second pilot tried to intervene, was put out of commission but at the same time the rest of the flight crew rushed in and took control away from the pilot. At that point, whether the first pilot was conscious or unconscious/dead, there was nobody able to fly the plane or even communicate with anyone. The plane then flew on in some random direction as we’ve been led to believe, and crashed into the ocean when fuel ran out.
