Triangular object over Boulogne-Billancourt, 1997

Summary

In September 1997, a witness in Boulogne-Billancourt reported a triangular object with lights moving slowly across the sky. He described vibrations and camera malfunctions during the sighting. Initially classified as unexplained, GEIPAN later reversed the assessment. Contradictions between the original testimony and a subsequent version undermined reliability. The witness edited a mystery magazine and published the case in his own publication, raising concerns about personal motivation. With no physical evidence to support the observation, GEIPAN concluded the testimony was insufficiently reliable to sustain an unexplained classification.
