Media talking heads are obessing about the fact that pro-Russian militia in Ukraine might steal the black boxes from Malaysian Airlines Flight MH-17 wreckage along the Ukraine-Russian border.
This crash was not an accident that needs to be investigated. We know what happened. A commercial passenger plane was peacefully flying along over Ukraine air space at 33,000 feet when it was suddenly blown out of the sky by an air-to-surface missile.
There is no mystery about why the plane came down that needs to be solved. There is also very little mystery about who was responsible and why. There is no data in a black box that can prove one way or another exactly who gave the order to fire the missile but we can reasonably infer what kind of missile it was, who made it, and who had the ability to fire it.
