Alien Fast-Food War

When remote-controlled aircraft begin behaving erratically, even crashing, the hobbyists rise to the occasion. Discovering that people who've eaten at fast-food restaurants are generating signals that cause the problem is strange. Of course, we've known all along the stuff in unhealthy. But this?

There is no reason for restaurants to do this, and that leaves only one logical explanation - someone is running experiments. There are only two possible suspects - it's either the government or there has been a secret alien invasion. The idea of having aliens are among us is no big deal, but if they won't stop, this means war.
