🇺🇸 USAF — Project Blue Book
On June 12, 1952, an Air Force officer reported an unidentified aerial phenomenon near Randolph AFB, Texas. The officer, who was passing through the area, observed between 15 and 20 bright objects for half an hour. He described them as appearing suddenly and disappearing without fading, moving rapidly and erratically. Some even followed perfect sine-wave patterns. Despite clear weather, no photos were taken and no physical evidence was found.
The official conclusion suggested possible birds, though the speed and movement patterns did not match typical avian behavior. The report was filed without a definitive explanation, leaving open the possibility of an unexplained phenomenon.
