UFO: It’s not strictly a military term, but much is made of Air Force reports of UFOs by conspiracy theorists and alien enthusiasts. Without getting into an argument about whether or not aliens are real, UFOs are just unidentified flying objects. The Air Force recording 12,618 of them from 1947 to 1969 does not mean that alien spacecraft have flown 12,618 or more sorties over American soil. It means that there have been 12,618 recorded sightings or sensor contacts of objects in the air. A balloon in an unexpected spot can be recorded as an unidentified flying object.
