Between January and early February 2013, a witness in Villemomble, a northeastern suburb of Paris, reported recurring observations of yellow lights appearing in the southeastern sky. The witness described the lights as appearing, moving slightly, then disappearing in a consistent pattern. These observations occurred multiple times over several weeks, always in the same general direction and under similar conditions.
GEIPAN's investigation revealed that the witness's observation direction corresponded precisely with the approach corridor for Orly Airport, located approximately 20 kilometers away. The sightings correlated directly with westerly or northwesterly wind conditions, which determine runway approach patterns at Orly. During these wind conditions, aircraft approaching from the south align with the runway, creating a flight path that brings them directly toward observers in Villemomble.
The investigation determined that the witness was observing the highly directional landing lights of commercial aircraft on final approach to Orly. At the 20-kilometer distance, these powerful landing lights were visible, but the aircraft were too far away for the witness to distinguish standard navigation lights (red-green position lights) or anti-collision strobe lights. The witness only saw the lights when aircraft were facing directly toward them, explaining the sudden appearance and disappearance pattern. Significantly, the witness did not observe the phenomenon on February 12-13, when wind patterns shifted to northeasterly or southerly directions, forcing Orly approach patterns to change to westerly routes—confirming the correlation with aircraft traffic patterns.
02 Timeline of Events
January 2013
Initial Recurring Observations Begin
Witness begins observing recurring yellow lights in southeastern sky during westerly/northwesterly wind conditions. Lights appear, move slightly, then disappear.
Early February 2013
Continued Sightings
Pattern continues throughout early February during periods of west/northwest winds, maintaining consistency with previous observations.
February 11, 2013
Official Report Filed
Witness files formal report with GEIPAN regarding recurring observations of yellow lights over previous weeks.
February 12-13, 2013
Phenomenon Not Observed
Witness does not see the lights on these dates. Wind patterns had shifted to northeast/south, changing Orly approach routes to westerly paths.
Post-February 13, 2013
GEIPAN Investigation
GEIPAN correlates witness observation direction with Orly Airport approach corridors, analyzes wind patterns, and determines aircraft explanation. Case classified as 'B' - probable aircraft identification.

04 Analyst Notes -- AI Processed
This case demonstrates exemplary investigative methodology by GEIPAN, showing how meteorological data, aviation traffic patterns, and witness observation direction can conclusively explain aerial phenomena. The correlation between observation dates and prevailing wind directions at Orly Airport provides compelling evidence for the aircraft explanation. The witness's inability to see the phenomenon on specific dates (February 12-13) when wind patterns changed serves as a natural control experiment, strongly supporting the conventional explanation.
The case highlights a common misidentification pattern: highly directional landing lights viewed from distance can create the impression of anomalous behavior, especially when the aircraft structure itself is not visible. At 20 kilometers, atmospheric conditions, lighting angles, and the directional nature of landing lights can create the illusion of lights appearing and disappearing without visible connection to an aircraft. The witness's location in the direct approach path, combined with their southeast viewing direction toward Orly, creates perfect conditions for this misidentification. GEIPAN's practical suggestion that the witness consult real-time air traffic monitoring tools demonstrates a solution-oriented approach to witness education.

BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Textbook Aviation Misidentification
This represents a classic example of how unfamiliarity with aviation operations and lighting characteristics leads to UFO reports. The witness's position directly under the Orly approach path, combined with atmospheric conditions and the physics of directional lighting, created an illusion of anomalous behavior. The natural experiment provided by changing wind patterns on February 12-13 definitively rules out any unconventional explanation.
06 Verdict
ANALYST VERDICT
This case is conclusively explained as misidentification of commercial aircraft landing lights on approach to Orly Airport. The evidence is overwhelming: perfect correlation between observation direction and Orly approach corridors, direct relationship between sighting dates and westerly wind patterns (which determine approach routes), cessation of observations when wind patterns changed, and the 20-kilometer distance explaining why only directional landing lights were visible. GEIPAN's 'B' classification (probable identification) is appropriate, though the evidence is strong enough to border on 'A' (certain identification). This case has minimal significance for UAP research but serves as an excellent educational example of how aviation traffic, meteorology, and observer position combine to create seemingly mysterious phenomena. The witness's recurring observations and genuine reporting demonstrate good faith, while the investigation showcases how systematic analysis can resolve apparently anomalous events.
