🇺🇸 USAF — Project Blue Book
In August 1953, a civilian witness in Stalingrad, USSR, observed an unusual aerial phenomenon. They saw a vapor trail similar to half a normal vapor trail, rising quickly into the sky. Shortly after, a light appeared in the sky, though the description is vague and repetitive. The witness observed the phenomenon for 3 to 4 minutes from the ground. No photos were taken and no physical evidence was found, limiting further investigation. The official conclusion was that it was an aircraft, citing a specific flight in the records.
