Chalons-sur-Marne 1977 Silent UFO

Summary

On November 12, 1977, two people in Chalons-sur-Marne observed a luminous object with an elongated shape. Initially stationary, the object began to rise slowly before vanishing suddenly into the clouds. The witnesses noted that the event lasted more than twenty seconds and no unusual noise was heard. No military exercises were recorded at the nearby military base that day. Researchers concluded it was likely a weather balloon illuminated by the setting sun, although the detailed description and unusual behavior of the object generated some interest.

The case was classified as "B" by GEIPAN, meaning it is not considered an unexplained phenomenon but still worth documenting. Despite the plausible explanation, the testimony provides a coherent and consistent account, which keeps some mystery around the observation. Cases like this, though not definitively resolved, enrich the database of unidentified aerial phenomena and help researchers better understand natural or technological phenomena that may be mistaken for UFOs.
