full, unidentified flying object, often abbreviated UFO or U.F.O., is an unusual apparent anomaly in the sky that is not readily identifiable to the observer as any known object. Originally referred to popularly as “flying saucers” during the late 40’s, the term UFO became more widespread during the 50s at first in professional literature, but later in popular language. UFOs garnered considerable interest during the Cold War, an era associated with a hightened concern for national security. Various studies, both governmental and civilian, have concluded that the phenomenon does not represent a threat to national security nor does it contain anything worthy of scientific persuit, although there is disagreement. Culturally, the phenomenon has often been associated with extraterrestrial life or government-related conspiracy theories, and thus has become a popular theme in fiction. 2011,2012, 2013,
