Inconclusive photographs after a sighting in Paris

Summary

In August 1997, a witness in Paris observed and photographed two unidentified objects in the sky. After contacting a science magazine, an investigation was opened: gendarmes visited the witness and analysed the slides developed at a private laboratory. The results were inconclusive — the described object did not appear on the slides, and an artefact on a paper print was interpreted as a hollow pentagon that the witness did not recognise as what he had seen, suggesting possible psychological influence or false memory. GEIPAN classified the case as C due to insufficient reliable information.
