Unidentified flying object (UFO), represent any observed phenomenon in the air which can not be determined. The term was coined in 1952 by the U.S. Air Force introduced to refer to a separate class of observations that remain unexplained chronic. The investigation is called ufology. Most UFOs later turn out to be ordinary natural phenomena or artificial light.
Since the late 40 years of the twentieth century the term UFO used as such, especially after Roswell accident, in an official press release was denounced as an observation balloon. Much later in the year 1990 , brought the U.S. Air Force in response to a letter written by Steven H. Schiff and directed to the GAO (Government Accounting Office), a new report in which he announced that the creatures which were found at the crash were actually weather balloons test dummies. These dummies were only developed in the year 1950, several years after the crash. The term flying saucer came into use after the description by the American businessman and pilot Kenneth Arnold of foreign objects that he saw at June 24, 1947.
