Claude Poher Studies
Claude Poher was a CNES rocket scientist who analysed the UFO data himself, concluded it showed structure rather than noise, and convinced the French space agency to create a programme to study it. These are the studies that made that argument.
The Scientist
Most government UFO programmes started the same way: public pressure or Cold War anxiety forced a response, and whoever was available got the brief. GEPAN was the exception. It started because a working scientist inside a space agency looked at the numbers and decided something real was in the data. Bottom-up scientific curiosity, not top-down political management.
Claude Poher's 1977 statistical analysis pulled together thousands of reports and found patterns that random misidentification could not explain. Correlations in time, geography, witness demographics, object characteristics. Witnesses from different countries and decades, none in contact with each other, described objects with consistent physical properties and behaviour. The data had structure.
The 1977 study circulated internally at CNES and landed on the right desks. Within months, GEPAN existed. One internal research paper, written by one engineer on his own initiative, created a government UFO programme that still operates today under the name GEIPAN. Few scientific papers anywhere have had that direct an institutional consequence.
Legacy
Poher became GEPAN's first director and built the programme from scratch inside CNES. He set the methodological culture: data-driven, statistically grounded, agnostic about explanations until the evidence pointed somewhere specific. That culture outlasted him.
After leaving GEPAN, he continued private research into propulsion concepts inspired by his UFO data work. The programme he founded survives as GEIPAN and still receives, classifies, and investigates UFO reports from French citizens and military personnel. His founding studies are where it all started.
Poher's statistical methods carried forward into GEPAN's Technical Notes series, which refined and extended his approach over two decades. The Valensole encounter was among the French physical-trace cases that Poher's statistical analysis drew upon. French sighting data from across the archive is on the France sightings page.

GEPAN was authorised by CNES Director General to collect, analyse, and publish data on unidentified aerospace phenomena using the full resources of the French space programme. The mandate was explicit: scientific investigation, open publication, and the same analytical rigour applied to any other aerospace research. No classification by default. No suppression of inconvenient findings. A government programme built from the start around transparency.
The field investigation reports that Poher's methodology produced are in the Field Investigations collection, covering GEPAN-dispatched site visits between 1979 and 1986. French sighting data from across the archive is on the France sightings page.
