UFO sighted in Pennsylvania in 1966

Summary

In January 1966, a civilian observer in Pennsylvania reported a UFO with a saucer-like appearance. The object appeared suddenly in the night sky, emitting a blue-white light and leaving a visible trail. The witness described a round shape with a sharp edge and a bright, metallic appearance. The object moved rapidly from northeast to southwest, maintaining a straight and constant path. The sighting lasted between 3 and 10 seconds, limiting the observer's ability to gather more details. Although no sounds or physical evidence were recorded, the testimony was documented by U.S. Air Force authorities. The report did not reach a clear conclusion but suggested it could have been a high-speed aircraft with landing lights illuminated.
