🇺🇸 USAF — Project Blue Book
In August 1957, a witness in Pueblo, Colorado, observed two unidentified flying objects. Both were round, the size of a fingertip, and white in color. One was above the other. While one moved east for 5 to 10 seconds, the other moved north for 7 minutes. The report, classified as likely an aircraft, does not offer a definitive explanation. The observer used binoculars, and no photographs were taken. The detailed description suggests a clear observation, but without radar confirmation or other means.
The officer in charge concluded it was probably an aircraft, citing even a speed similar to that of a Convair. However, the nature of the movements and the duration of the observation raise questions. Despite the official assessment, the case remains unresolved, adding a touch of mystery to this event from over half a century ago.
