The Sparrow-N from E.M.I.T. The unmanned aerial vehicle weighs 40 kilograms, far less than the 200 kilo average, and can fly at 3,000 feet without being detected. Most fly at higher elevations. At 3,000 feet, the camera in the plane can still bring back images that correctly identify individuals. It also costs a lot less and can be launched with a bungee-cord contraption mounted on the roof of an assault vehicle.
