🇺🇸 USAF — Project Blue Book
In 1963, a witness in Natrona, Pennsylvania, reported seeing a bright white object moving from the southwest to the east. The light was observed for approximately five to ten minutes. Although initially thought to be a UFO, investigators concluded the object was the satellite Echo 1. This satellite, launched by the United States, was known for its high visibility and was often mistaken for unidentified objects. The report details the satellite's exact location at the time, matching the witness's description. Despite no physical evidence, the description and location aligned with the orbital data of Echo 1.
