🇺🇸 USAF — Project Blue Book
A Turkish officer reported a glowing object near the Uzundzhovo airfield in Bulgaria. The object moved slowly and was tracked by anti-aircraft searchlights. On several occasions, the object would disappear and reappear at the same location. A jet aircraft passed close to the object but did not identify it as such. Observers heard no engine noise and saw no smoke, raising doubts about its nature. Although a balloon or illuminated target was considered, no definitive conclusion was reached. The report suggests it could have been a training exercise, but certainty remains elusive.
