🇺🇸 USAF — Project Blue Book
A 1963 report describes how a witness in Thaxton, Virginia, initially believed he had seen a bright, silver unidentified flying object (UFO) in the sky. However, upon approaching the phenomenon, he discovered it was thistle blooms floating in the air. These blooms, measuring between 1 and 1.5 inches in diameter, were highly reflective under the sunlight and moved with the wind, creating the illusion of large objects at great distances. The case was analyzed by the U.S. Air Force, which categorized it under "angel hair"—natural phenomena that can be mistaken for unconventional aerial objects.
The Air Force responded to the report with interest, acknowledging that phenomena such as spider webs, chemical plant residues, or silver halide particles from cloud seeding operations could explain similar sightings. The observer, a civilian, even sent samples of the thistle blooms, suggesting that drying them and moving them with fans could recreate the phenomenon. The case highlights how human perception, especially under favorable weather conditions, can lead to misinterpretations of natural objects, resulting in UFO reports that are later resolved with earthly explanations.
