🇺🇸 USAF — Project Blue Book
In September 1956, a bright white object was seen for ten minutes above San Antonio, Texas. Four witnesses described it as a circle the size of a nickel held at arm's length. The object initially appeared like a falling star but grew in size as it approached. It moved erratically from the northwest to the southeast, making unexpected turns. Despite the duration of the observation, reports concluded there was not enough information to determine its nature. No aircraft sightings or weather data explained the phenomenon, leaving the case unresolved.
