Blue ball falling behind a quarry at Montréjeau

Summary

Early one morning in September 1994, a witness in Montréjeau (Haute-Garonne) saw a blue ball fall rapidly behind a quarry without making any sound. After the apparent impact, blue lights remained visible behind the mountain. The witness woke their partner, who only saw the residual lights.

GEIPAN classified the case B, suggesting a plausible explanation, most likely an atmospheric phenomenon. The rural location and early hour limited the number of available witnesses.
