🇺🇸 USAF — Project Blue Book
In December 1965, a civilian observer in Aberdeen, South Dakota, reported the presence of luminous objects in the sky that changed colors. One object shifted from white to red, blue, and green, while two others also displayed color changes, though not always in the same sequence. The objects did not follow a discernible formation and remained visible for approximately 39 minutes. The observer described the phenomenon as resembling an exploding star, similar to neon signs used to attract attention. The observation occurred at a high altitude in the southeastern quadrant of the sky, and no sounds or sudden movements were noted. Despite immediate investigations, no conventional explanations or physical evidence were found.
