White object watched for ten minutes in Maisons-Alfort

Summary

On 13 August 1988, a witness in Maisons-Alfort, Val-de-Marne, watched a white object in the sky for about ten minutes. He initially thought it was a microlight, but something about its appearance struck him as unusual. No strange movements or out-of-the-ordinary behaviour were described. GEIPAN recorded the case as B—available data did not allow a conclusive identification, though nor did they point to a clearly anomalous phenomenon.
