On October 27, 1989, at approximately 09:00, a farmer (T1) discovered a large scorched area in his field near Brix, Normandy. The burn trace measured approximately 17 meters long by 4 meters wide at its widest point, with irregular shape. The affected area showed complete vegetation loss, blackened soil, and the ground was spongy and sunken 10-15 cm below the surrounding meadow level. A 20 kV high-tension power line ran approximately 50 meters from the burn site.
A second witness (T2) reported to local gendarmerie that during the night of October 25-26, 1989, around 02:00, their dog exhibited strange behavior and they observed a large beam of intense bluish light above the field in question. The local police brigade, unable to determine the origin and cause of the phenomenon, contacted SEPRA (Service d'Expertise des Phénomènes de Rentrées Atmosphériques), the official French government agency for investigating aerospace phenomena, which dispatched investigators to the site.
SEPRA conducted soil core sampling which revealed the earth was burned to a depth of 2-3 cm, with gray-colored clay indicating exposure to high temperatures. Soil samples from the affected zone emitted a strong odor of petroleum products. Laboratory analysis confirmed the presence of kerosene in the samples. The investigation noted strong crackling sounds from the power line at certain insulator junctions, suggesting electrical arcing. GEIPAN classified this case as 'B' - physical traces left by a fire with probable conventional explanation.

1989-10-25/26 ~02:00
Nighttime Light Phenomenon Observed
Witness T2 observes large beam of intense bluish light above the field. Their dog exhibits strange behavior. T2 later describes seeing a very large blue flame in the area.
1989-10-27 ~09:00
Burn Site Discovery
Farmer T1 discovers large scorched area in field measuring approximately 17m x 4m. Ground is blackened, vegetation completely destroyed, soil sunken 10-15 cm with spongy texture.

Local Police Investigation Begins
Local gendarmerie brigade investigates the site but cannot determine origin or cause of the phenomenon. They contact SEPRA for expert assistance.

SEPRA On-Site Investigation
SEPRA investigators arrive quickly to examine the site. They document the 20 kV power line 50m from trace, observe strong crackling sounds at insulator junctions, and conduct soil core sampling.
Post-investigation
Laboratory Analysis Results
Soil samples analyzed reveal burning to 2-3 cm depth, gray clay coloration indicating high temperature exposure, strong petroleum odor, and confirmed presence of kerosene.
Final
Case Classification
GEIPAN classifies case as 'B' - physical traces left by fire with probable conventional explanation: aircraft fuel dumping ignited by power line arcing.

04 Analyst Notes -- AI Processed
This case demonstrates exemplary scientific investigation methodology by SEPRA/GEIPAN. The presence of physical evidence (17m burn trace, soil deformation, chemical residue) combined with witness testimony created an initially mysterious scenario that warranted official investigation. The discovery of kerosene through laboratory analysis provided a critical evidentiary breakthrough that pointed toward a conventional explanation rather than an anomalous phenomenon.
Several corroborating factors support the official conclusion: (1) chemical analysis definitively identified kerosene in soil samples, (2) witness T2's observation of intense blue flame is consistent with hydrocarbon combustion characteristics, (3) proximity to high-tension power lines with documented electrical anomalies (crackling/arcing at insulators) provides a plausible ignition source, (4) the irregular burn pattern matches what would be expected from aerial fuel dispersal and ground fire spread. The hypothesis of low-altitude, slow-speed aircraft fuel dumping followed by ignition via power line arcing is well-supported by the physical evidence. The 10-15 cm ground depression could result from intense heat causing soil compaction and moisture evaporation. This case illustrates how seemingly anomalous events can be resolved through systematic scientific investigation and chemical analysis.
05 Theory Comparison
BELIEVER ANALYSIS
Unexplained Aerial Phenomenon with Residual Effects
Some might argue the intense bluish beam observed by T2 preceding the burn trace, combined with the dog's unusual behavior and the geometric nature of some burn patterns, suggests an unconventional explanation. However, this interpretation is not supported by the chemical evidence of kerosene, which definitively points to aviation fuel rather than unknown energy sources. The blue light is entirely consistent with hydrocarbon fire rather than exotic phenomena.
SKEPTIC ANALYSIS
Undocumented Aviation Incident
The kerosene evidence is definitive, but questions remain about the aviation source. Why would an aircraft dump fuel at low altitude over populated areas of Normandy? No flight records or pilot reports have been referenced in the available documentation. Alternative scenarios could include illegal dumping, agricultural aviation accident, or military exercise mishap that went unreported. The lack of identified aircraft or official aviation incident report leaves a documentary gap, though the physical evidence clearly indicates hydrocarbon fuel as the source.
06 Verdict
ANALYST VERDICT
GEIPAN's Classification B assessment is well-justified. This case almost certainly involved accidental aviation fuel dumping (kerosene) from a low-flying aircraft during the night of October 25-26, 1989, which was subsequently ignited by electrical discharge from the nearby 20 kV power line. The bluish light observed by witness T2 at 02:00 was the resulting hydrocarbon fire, not an unidentified aerial phenomenon. The presence of confirmed kerosene residue, combined with the blue flame observation (characteristic of burning hydrocarbons) and documented power line electrical anomalies, provides a comprehensive conventional explanation. While the initial discovery was certainly unusual and worthy of investigation, the scientific evidence points conclusively to an aviation incident rather than an unexplained phenomenon. The case's significance lies in demonstrating how proper forensic investigation can resolve apparently mysterious events.
