On March 18, 2013, a witness in Domont, France (Val-d'Oise department) observed five luminous orange and white points in the sky above a building across from his residence for over an hour. Describing the phenomenon through binoculars as resembling 'an orange on fire,' the witness became sufficiently concerned to contact the gendarmes (French police), who came to the location and also observed the lights appearing and disappearing. The witness captured multiple photographs of the phenomenon across several image sequences (IMG_0546-0873 series). GEIPAN (France's official UFO investigation service under CNES) conducted a thorough analysis using photographic evidence, aeronautical charts, and Google Earth triangulation. Their investigation revealed that photo IMG_0873.jpg showed a light source at an azimuth of 266°, which precisely matched approach path 27R at Paris-Charles de Gaulle Airport (Roissy-CDG). The analysis demonstrated that a line drawn between the landing point on runway 27R and the witness's position passed exactly between two buildings visible in the photographs, matching the alignment of the three luminous points observed. Additional photographs (IMG_0546, 547, 549) captured departures from runway 09R/27L, while images IMG_0688, 689, 690 showed simultaneous departures from runways 08L/26R and 09R/27L, including a light aircraft that took off well before reaching the end of the runway. GEIPAN's technical analysis of runway operations at CDG confirmed that outer runways (08R/26L and 09L/27R) are preferentially used for arrivals, while inner runways (08L/26R and 09R/27L) handle departures, with simultaneous parallel operations being standard procedure.

04 Analyst Notes -- AI Processed
This case represents an exemplary scientific investigation demonstrating how rigorous methodology can resolve apparently anomalous sightings. GEIPAN's analysis employed multiple verification techniques: photographic analysis measuring angular direction (86.28°), cross-reference with official aeronautical approach charts (AIP France CDG documentation), and Google Earth spatial modeling to confirm geometric alignments. The precision of the triangulation—with sight lines passing 'exactly in the middle between two buildings'—provides compelling corroboration. The witness's credibility is actually enhanced by their actions: they observed carefully with binoculars, involved law enforcement authorities, and documented the event photographically. Their description of 'an orange on fire' is consistent with the appearance of aircraft landing lights viewed head-on, particularly during twilight when contrasts are heightened. The gendarmes' corroboration confirms the phenomenon was real and visible, ruling out individual perceptual issues. The case illustrates how unfamiliarity with local air traffic patterns, combined with unusual viewing angles and lighting conditions, can transform mundane aircraft into mysterious phenomena. The witness's position relative to CDG's complex four-runway configuration created optimal conditions for misidentification of simultaneous arrivals and departures.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Textbook Aircraft Misidentification
This case demonstrates classic conditions for aircraft misidentification: witness unfamiliarity with local air traffic patterns, unusual viewing angle (head-on to approach path), distance creating atmospheric distortion effects, and complex multi-runway operations creating appearance of 'appearing and disappearing' lights as different aircraft enter and exit the approach corridor. The witness's location in Domont placed them on a direct line with CDG's primary approach paths, making this scenario inevitable during busy traffic periods.
06 Verdict
ANALYST VERDICT
GEIPAN's Classification A rating indicates complete identification with high confidence. The evidence is conclusive: the witness observed commercial aircraft operating on standard approach and departure paths at Paris-Charles de Gaulle Airport, approximately 15-20 kilometers from Domont. The geometric precision of the triangulation analysis, combined with perfect correspondence to published aeronautical approach procedures and photographic evidence clearly showing aircraft silhouettes, eliminates any reasonable doubt. This case serves valuable educational purposes, demonstrating how civilian aircraft operations—particularly at major international hubs with multiple parallel runways—can appear mysterious when viewed from specific angles and distances. The involvement of law enforcement and the witness's genuine concern underscore that misidentification does not imply lack of observation skills, but rather unfamiliarity with complex aviation environments.
