Athis-Mons, 1980 UFO sighting

Summary

On September 14, 1980, an air traffic controller on duty observed an unusual phenomenon. At 12:45 PM, he saw a black cylindrical object hovering directly above him. The object, located about 300 meters above the ground, suddenly accelerated and disappeared to the east. Despite the observer's professional background, no additional information was gathered that could support a serious analysis of this sighting. Such brief observations are of interest to researchers due to the clear description and the testimony of a qualified individual. However, the lack of supplementary data limits the possibilities for further study.
