🇺🇸 USAF — Project Blue Book
An observer in Murfreesboro, Tennessee, reported in 1960 a bright object resembling a very luminous star, similar to Venus. The object, described as a smooth disc, appeared overhead and gradually approached over five minutes. It then disappeared and was replaced by seven small bright points that also faded in one minute. The witness, a registered engineer and engineering professor, used a simple telescope to observe the phenomenon. Despite his five years of astronomy experience, he couldn't identify the object.
The Sewart Air Force Base concluded that the sighting matched the description of a balloon in flight and then bursting. Weather data and the object's direction supported this theory. However, the report also noted that the object had no tail or noise, characteristics that ruled out an aircraft. Ultimately, the case was classified as a balloon sighting, although the official report didn't completely rule out the possibility of an unusual natural phenomenon.
