On Monday, October 31, 2016, at approximately 4:30 PM, multiple individuals gathered in a sunroom in Outreau, Pas-de-Calais, observed two ovoid-shaped objects of cream or white coloration traversing the clear sky. The objects moved in a straight, rectilinear path from west to east before progressively distancing themselves and disappearing from view. Despite multiple initial observers, only a single formal witness testimony was collected by GEIPAN investigators.
The witness, who was not a local resident and therefore unfamiliar with typical aerial phenomena in the region, reported objects that appeared wingless and ovoid. The sighting occurred under specific atmospheric and solar conditions: the sun was positioned behind the witnesses at 4:30 PM, creating optimal conditions for sunlight to reflect perpendicularly off aircraft fuselages. The objects appeared at approximately 10° elevation above the horizon, consistent with aircraft flying at 10 km altitude at a distance of approximately 50 km near Gravelines, along a known air corridor entering France from the west.
GEIPAN's investigation determined the objects were aircraft traveling in the established air corridor above Gravelines, approximately 50 km from the observation point. The apparent trajectory gave witnesses the impression the objects passed over Boulogne and Saint-Leonard. The unique solar angle created a mirror effect on aircraft fuselages, causing wings to blend visually with the body and producing the characteristic ovoid appearance. Aircraft measuring 20-80 meters in length at this distance would present angular sizes between 1/20 to 1/5 that of the full moon—sufficient to perceive an ovoid shape but small enough to lose wing definition.
02 Timeline of Events
16:30
Initial Observation
Multiple witnesses in sunroom observe two cream or white ovoid objects appearing in clear sky, moving in rectilinear path from west to east
16:30-16:35
Objects Display Unique Characteristics
Witnesses note wingless, ovoid appearance of objects at approximately 10° elevation. Objects appear to move in two parallel horizontal lines at different apparent speeds
16:35+
Objects Recede from View
Objects progressively distance themselves and disappear from witness view, moving along trajectory appearing to pass over Boulogne and Saint-Leonard
Post-incident
Single Testimony Collected
Despite multiple initial observers, only one formal witness testimony submitted to GEIPAN for investigation
Investigation
GEIPAN Analysis Conducted
Investigators analyze air corridor data, solar angles, optical physics, and photographic evidence. Determine objects were aircraft at 10 km altitude, 50 km distance over Gravelines, with sunlight reflecting perpendicular to fuselage creating wingless ovoid appearance
Conclusion
Case Classified 'B'
GEIPAN officially classifies case as 'B' - probable aircraft observation under specific optical conditions. High confidence explanation identified.

"Two ovoid objects of cream or white color moving in straight line across clear sky, progressively moving away until hidden from view."
04 Analyst Notes -- AI Processed
This case represents a textbook example of aerial misidentification under specific optical conditions. GEIPAN's classification as 'B' (probable explanation identified) reflects high confidence in the aircraft hypothesis based on multiple corroborating factors: known air corridor location, precise solar angle calculations, witness unfamiliarity with local airspace, and optical physics of sunlight reflection on metallic surfaces.
The witness credibility is not questioned, but contextual factors significantly influenced the perception. The observer's status as a non-resident is crucial—local inhabitants familiar with regular air traffic patterns would recognize this phenomenon and likely not report it. The specific time (4:30 PM on October 31) places the sun at an angle conducive to perpendicular reflection off aircraft at specific headings. The description of 'two parallel horizontal lines at different speeds' aligns perfectly with aircraft at varying distances in the same corridor, creating apparent speed differentials due to perspective. The photographic evidence mentioned (though not provided in detail) reportedly shows objects at the predicted 10° elevation, further validating the aircraft explanation.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Atmospheric Optical Illusion Enhanced by Observer Bias
The sighting represents a confluence of optical factors and observer psychology. The non-resident witness, potentially primed by cultural expectations around Halloween (October 31), observed routine air traffic under unusual lighting conditions. The sunroom environment may have contributed glare or reflection effects. The fact that only one of multiple observers provided testimony suggests others present recognized the aircraft nature of the objects. The 'ovoid' description is consistent with fuselage-only visibility when wings are visually merged due to viewing angle and atmospheric scattering. No unusual flight characteristics were reported—only unusual appearance due to environmental conditions.
06 Verdict
ANALYST VERDICT
GEIPAN's conclusion that this sighting represents probable aircraft observation is well-founded and supported by comprehensive analysis. The convergence of known air traffic patterns, precise optical calculations regarding solar reflection angles, witness unfamiliarity with local airspace, and the physical impossibility of seeing aircraft wings under these specific viewing conditions provides a compelling mundane explanation. The case demonstrates how extraordinary perceptions can result from ordinary phenomena viewed under unusual circumstances. Confidence level: Very High (95%+). This case holds minimal significance for UAP research but serves valuable educational purposes in understanding how atmospheric optics, perspective, and observer context combine to create anomalous reports. It exemplifies the importance of local knowledge and environmental factors in witness testimony evaluation.
