Micro Air Vehicles are the hot new drone for 2013, or whenever they’re actually created by the Air Force. In this simulated video, MAVs look like horrifying flying things that are “unobtrusive, pervasive, lethal.” These tightly controlled drones can spy, scan and shoot someone in the head. And these MAVs would range from the size of a bird to a fly. At least these nightmares will be unobtrusive. That’s polite of them.
