🇺🇸 USAF — Project Blue Book
In March 1953, an Air Force officer and his wife observed several luminous objects in the sky over San Antonio, Texas. The witnesses reported that the objects, similar to stars, moved from north to south and made full circles before disappearing. The observation lasted an hour and a half using binoculars, but radar attempts found nothing. Investigators ruled out known phenomena such as aircraft or meteors and considered the possibility of lights reflected off clouds or high haze. However, there were no cloud records that day, adding mystery to the case.
The Air Force classified it as "unidentified," and expert comments suggest it could have been an optical phenomenon, though no definitive explanation was found. This case is part of the Blue Book Project files and remains an enigma for UFO researchers.
