On the night of March 30-31, 2007, four young witnesses near Dompaire in the Vosges department observed what they described as a metallic triangular object with white and red lights moving erratically through stormy, black skies. The observation occurred intermittently over approximately six hours, from 20:00 to 02:00. The witnesses reported the triangle performing back-and-forth movements at variable speeds before passing approximately 15-20 meters above their vehicle. The experience left the witnesses "strongly impressed" by what they had seen.
GEIPAN's official investigation conducted a thorough analysis of air traffic in the sector and identified the source of the sighting with high certainty. Records confirmed that a Swiss airline Hello AG MD-90 (DC-9) aircraft from Zurich was conducting crew training exercises at Epinal-Mirecourt airport during the exact timeframe of the observations. The aircraft performed 30 "touch and go" landing practices in the afternoon after detecting a technical problem, then resumed these training rotations between 19:47 and 21:16 before final departure to Zurich at 21:45. A freight aircraft also landed at Epinal at 01:58, near the end of the observation period.
The investigation concluded that the witnesses were consistently positioned under the flight path of the training aircraft during unusual nighttime operations around Epinal-Mirecourt airport. GEIPAN investigators noted that the witnesses themselves acknowledged mistaking stationary lights from streetlamps or cars for moving objects during their travels that night, suggesting a heightened state of misperception. The case received a Classification A rating from GEIPAN, indicating complete identification with certainty.

03 Key Witnesses
Anonymous Witness Group
Civilian (4 young witnesses)
medium
Group of four young friends traveling by vehicle near Dompaire during nighttime hours. Self-reported instances of misperceiving stationary lights as moving objects during the same observation period.
"The lights formed a metallic-colored triangle that moved back and forth at variable speeds before passing about 15 to 20 meters above our vehicle."
04 Analyst Notes -- AI Processed
This case demonstrates a textbook example of aircraft misidentification under specific contributing conditions: nighttime observation, stormy weather conditions reducing visibility, witnesses unfamiliar with aircraft training operations, and the unusual flight patterns of touch-and-go exercises creating seemingly erratic movements. The 15-20 meter altitude estimate by witnesses is almost certainly inaccurate—a common perceptual error when judging distances of lights at night without reference points. The actual aircraft would have been at standard approach/departure altitudes (hundreds of feet), but appeared closer due to low cloud cover and psychological factors.
The credibility assessment is complicated by the witnesses' own admission of misperceiving stationary lights as moving objects during the same evening, indicating a compromised observational state. The triangular shape reported is consistent with viewing an aircraft's light configuration from below at certain angles, particularly during banking turns common in touch-and-go patterns. The GEIPAN investigation's strength lies in its correlation of air traffic control records with witness testimony, providing documented proof of aircraft presence at the exact times and location. The Hello AG airline's regular use of Epinal for low-traffic training exercises adds further credibility to the explanation.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Perceptual Error Amplified by Environmental Conditions
The stormy weather conditions, darkness, and witnesses' acknowledged misperception of stationary lights created a perfect scenario for dramatic misidentification. The 15-20 meter altitude estimate demonstrates significant distance judgment error common in nighttime observations. The witnesses' own admission that they confused streetlamps and car lights with aerial phenomena during the same evening indicates compromised observational reliability. No extraordinary explanation is required when documented aircraft activity precisely matches the reported observations.
06 Verdict
ANALYST VERDICT
This case is conclusively explained as the misidentification of conventional aircraft engaged in routine training operations. The GEIPAN investigation provided documentary evidence matching aircraft movements to witness observations with temporal and spatial precision. The Classification A rating is fully justified. While the witnesses' experience was genuine and their initial perception understandable given the stormy conditions and unfamiliarity with touch-and-go procedures, no anomalous phenomena occurred. This case holds minimal significance beyond serving as an educational example of how standard aviation activities can be dramatically misperceived under specific environmental and psychological conditions. Confidence level: Very High (95%+).
