Recurring white sphere over Le Vaudreuil

Summary

At about 2:45 a.m. on 4 April 1978, a factory security guard near Le Vaudreuil spotted a white sphere at altitude above a wooded area. He saw it five times, noting changes in size and high-speed movement before it gradually faded into the sky. There were no other witnesses, images, or physical traces. GEIPAN classified the case as C due to insufficient data to determine the nature of the phenomenon.
