UFO....Unmanned Flying Objects

UFO means UNIDENTIFIED Flying Object, not UNMNANNED. There have been UNMANNED flying objects for ages... other than BIRDS, of course. Usually they are referred to as "Drones" and the military, in particularly, use them ALL the time. The police use them for surveilence. Even private companies use them for many purposes: aerial photography, monitoring, even for scaring off birds or other animals from airports for the sake of safe aircraft operations. Now... UNIDENTIFIED Flying Objects have been reported worldwide. Yes, they are real, because sometimes they are seen so briefly, one cannot identify them, or they are so distant they cannot be identified. That doesn't mean they are ALIENS from outer space! Most are natural or normal "phenomenon." Please refer to the US Air Force's report called "Project Blue Book."
