🇺🇸 USAF — Project Blue Book
In September 1952, a U.S. Air Force officer in Nebraska observed an unidentified flying object. The report describes two spherical silver objects that remained stationary before moving eastward. One of them returned and was observed for five minutes. The witnesses could not determine its speed or aerodynamic features. The official report concluded that the phenomenon could not be evaluated.
The report includes details on the exact location, weather conditions, and the absence of any meteorological or physical activity that could explain the sighting. Despite other aircraft being recorded in the area, there were no attempts at interception or identification. The observers' description, along with the accuracy of the data, adds credibility to the testimony, although no physical evidence was found to support the observation.
