This GEPAN technical note investigates a 1979 UFO sighting, concluding that the witness's evolving testimony was likely influenced by hypnosis and psychological factors rather than an extraordinary event.
NOTE TECHNIQUE N°6: ENQUETE GEPAN N° 79/07 - A propos d'une disparition
The GEPAN investigated a 1979 abduction claim in a Paris suburb and concluded it was a fabrication. The report documents significant witness contradictions and the exploitation of the story by media and private groups.
Note Technique No 8: Enquête No 79/06
A 1979 UAP sighting in France involving two witnesses and physical traces was investigated by GEPAN. The report concludes that while the witnesses were sincere, their accounts were heavily influenced by subjectivity, and no definitive physical evidence of an anomalous object was found.
