The drones are US UAV's looking for some nuclear material or chemical signature.

2. You are correct.

Cause if you are looking for nuclear material or a chemical signature you would most definitely want to make sure you have flashing lights to alert everyone around you of your presence including the said people hiding such things. Or if you are an alien then the sure way to hide is to pretend to be a drone with flashing lights so the whole nation is wondering what you are. I'm sure the technology to fly between stars does not include anything but the ability to hide as a drone with flashing lights. Perfect sense. There is no way it is just drones flown by the US government doing tests on their ability to operate in a civilian infrastructure, talk about far fetched conspiracy theories. What a dumb idea.
