Silent UFO observed in France in 1978

Summary

On December 11, 1978, witnesses across several regions of France observed a luminous phenomenon moving rapidly through the sky without producing any sound. A trail was also seen, and the object disappeared suddenly. Although unusual, researchers concluded it was likely a meteor or space object entering Earth's atmosphere. This case was classified as "B" by the GEIPAN, indicating a plausible but not fully confirmed explanation. The lack of noise and the object's speed sparked curiosity and discussion among observers.
