Hellenic Air Force Intercept 1990

On September 11, 1990, Hellenic Air Force F-104G Starfighters scrambled from Tanagra Air Base encountered a disc-shaped object at 20,000 feet over the Athens Flight Information Region. The pilots achieved brief visual contact with a structured metallic disc before the object performed a high-speed departure to the east. Athens civilian and military radar confirmed the contact. Greece filed a NATO incident report through standard NADGE procedures. The Hellenic Air Force, while not publicly disclosing the encounter, incorporated it into a growing domestic UAP investigation file that researchers obtained through Greek FOIA-equivalent legislation in the 2000s. The Greek file, when partially released, showed consistent patterns with Italian, Spanish, Portuguese, and Turkish military UAP encounters in the Mediterranean theater, contributing to the picture of sustained NATO-airspace UAP activity that allied nations were quietly accumulating since the 1950s.
