My favorite part is the part when they say "Aha! It's camoflauge! It LOOKS like an aeroplane but in fact it's a disguise!". I mean, what's next, a helicopter is chasing a drone and they say "Aha! The alien craft has disguised itself as one of our helicopters chasing one of our drones, who would suspect that!"

Anyway the non-alien conspiracy theories are along the lines of radiation sniffers for a suitcase nuke, drone tests for material transport between bases & offshore navy ships, red team vs blue team drone tests.
