Considering how well organized the attack seems to have been, I assume those behind it know a lot about airports/drones.

I wonder if it could be a government researcher worried about a lack of funding/preparation for this kind of attack (similar to the FBI's conclusion regarding the anthrax attacks)?

It doesn't seem like a protest, so unless it's economic terrorism or a state-backed attack, what else is it likely to be? A former pilot with a grudge?

Or a potential government contractor selling anti-drone technology.
