🇺🇸 USAF — Project Blue Book
In December 1968, a witness in Natrona, Pennsylvania, reported seeing an object that appeared like a star. The phenomenon was observed for a short period and was moving in a straight line. The report notes that the observer did not register any changes in the object's appearance and did not notice sounds or physical effects. Although described as luminous, it could not be identified with known celestial objects. The description is simple but clear, without indicating any abnormal characteristics beyond its movement and brightness.
