On Bastille Day evening, July 14, 2019, at 20:35 hours, a witness observing from a friend's residence in Billy-Montigny, Pas-de-Calais, noticed an unusual object in the sky. The witness described it as anthracite-colored (dark gray), with a matte finish that nevertheless reflected sunlight, appearing to approach at considerable speed. The object moved silently across the sky before disappearing toward the south-southeast. The entire observation lasted 25 seconds, during which the witness managed to capture a photograph. Friends present at the location later viewed the object on the witness's camera, though they did not observe it directly in real-time. GEIPAN (France's official UAP investigation service under CNES) conducted a formal investigation of case 2019-07-50871, employing their IPACO photographic analysis software and meteorological wind pattern analysis. The investigation determined the object to be approximately 0.80 meters in size with an elongated shape, possibly fish-shaped. Wind data analysis correlated with the object's observed trajectory and speed. The case received a GEIPAN Classification B, indicating a probable identification. The official conclusion identified the object as a festive helium balloon carried by wind currents. The witness's perception of strangeness stemmed from the unusual shape, complete silence, apparent rapid movement, and the rarity of observing such an object under these conditions. The witness remained unable to personally explain what they observed, despite the official findings.
02 Timeline of Events
20:35
Initial Detection
Witness notices anthracite-colored object in the sky while at friend's residence. Object appears matte but reflects sunlight, seeming to approach at rapid speed.
20:35 + 10s
Photographic Documentation
Witness captures photograph of the object without alerting friends present. Object continues silent movement across the sky.
20:35 + 25s
Loss of Visual Contact
Object disappears from view traveling toward the south-southeast. Total observation duration: 25 seconds.
20:35 + 30s
Secondary Verification
Friends present view the object on witness's camera display, providing indirect corroboration of the photograph.
Post-incident
GEIPAN Investigation Initiated
Official investigation launched. IPACO software analysis applied to photograph and meteorological wind data analyzed for the time and location.
Investigation conclusion
Classification B - Probable Identification
GEIPAN concludes object was likely a festive helium balloon (0.80m, fish-shaped or elongated) carried by wind. Case classified as B: probable identification.

Civilian observer
medium
Individual visiting friends in Billy-Montigny on Bastille Day 2019. Demonstrated initiative by photographing the object and providing follow-up information to investigators.
"The witness noted they could not explain what they observed, emphasizing the rarity of such a sighting and highlighting the unusual form, absence of sound, and apparent speed of movement."
04 Analyst Notes -- AI Processed
This case demonstrates solid investigative methodology by GEIPAN. The witness credibility appears reasonable - they immediately documented the sighting photographically and provided follow-up information during the investigation. The presence of friends who could verify the photograph (though not the sighting itself) adds a layer of corroboration. The witness's honest acknowledgment of inability to explain the phenomenon, combined with their detailed observation, suggests genuine puzzlement rather than fabrication. The GEIPAN analysis using IPACO software and meteorological data represents objective scientific investigation. The conclusion of a helium balloon is well-supported by multiple factors: the elongated/fish shape matches festive balloon designs, the silent movement is consistent with wind-borne objects, the trajectory aligns with analyzed wind patterns for that date and time, and the anthracite coloring could represent a dark-colored novelty balloon. The timing on Bastille Day (French national holiday) increases the likelihood of celebratory balloons being released. The 'rapid' movement perceived by the witness is a common misperception when observing objects of unknown size and distance, particularly when wind-carried.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Perceptual Misidentification of Mundane Object
The witness's perception of 'rapid' movement and unusual characteristics resulted from common observational errors when viewing objects of unknown size and distance. The silence is expected for any wind-borne object. The 'strangeness' stems from the unexpected context rather than genuinely anomalous properties. Dark-colored party balloons are common and easily misperceived when observed against the sky.
06 Verdict
ANALYST VERDICT
GEIPAN's Classification B designation appears well-justified. The convergence of photographic evidence, wind pattern analysis, timing (national holiday with celebrations), and the physical characteristics all strongly support identification as a festive helium balloon. The witness's perceived strangeness is adequately explained by the unusual nature of encountering such an object unexpectedly, combined with distance/size estimation difficulties. Confidence level: High (85%). This case is significant primarily as an educational example of thorough investigation methodology and how mundane objects can create compelling UAP reports when encountered in unexpected contexts. The 25-second observation with photographic evidence allowed for definitive analysis that many cases lack.
