As a third piece of debris said to be from doomed Malaysia Airlines flight MH370 has been found on La Reunion Island, it is time to ask what the government of Malaysia knew on the night of March 8, 2014 — exactly two years ago today — and why it acted the way it did.

Logic, and careful consideration of the public record, suggests that the motive for the disappearance of flight MH370 almost two years was known in high places of authority in Malaysia on the night the Boeing 777-200ER took off from Kuala Lumpur for Beijing with 239 people on board.

But why did the plane disappear? And who knew about it?
