🇺🇸 USAF — Project Blue Book
In July 1952, a radar technician in Marietta, Georgia, reported an unusual aerial phenomenon that drew attention due to its strange behavior. According to the report, an unidentified target appeared on the radar screen, moving slowly and then interacting with another signal related to wind measurements. The unknown object approached, passed through the signal, and returned, repeating the behavior several times. Eventually, it stopped for a few minutes before moving away. The technician, considered very reliable, described in detail the coordinates, altitude, and speed of the phenomenon, although no air traffic was recorded in the area. This case was considered one of the most intriguing of the time, as no conventional explanation was found.
