The black boxes were

The black boxes were "destroyed in the explosion" according to the dogmatic official reports.

I too have thought about the possibility that the steering system was hacked into. It certainly is a possibility.

The reason my inclination is to believe they were drones is because of their appearance. Eyewitnesses described black/grey colored, unmarked, military-type aircraft. I agree with these observations.

Either scenario involves the death of all passengers, unfortunately. I don't think the folks at Cleveland were kind enough to "send them on their way."
