On July 16, 1976, at 4:30 AM, a single witness observed a luminous phenomenon from a window of their residence in Colombes, a northwestern suburb of Paris in the Hauts-de-Seine department. The witness reported seeing what initially appeared as a single luminous point approaching their position. As the object drew nearer, it transformed into what the witness described as a 'rampe de lumières' (ramp or array of lights). When viewed from behind as it departed, the witness could distinguish two distinct luminous points displaying green and red coloration. The observation occurred during the pre-dawn hours when visibility would have been limited. Critically, the witness reported being unable to clearly discern any definitive shape of the object and noted hearing no unusual sounds during the sighting. The entire sequence appeared to show a progressive transformation of the light configuration as the object's position and orientation changed relative to the observer. GEIPAN classified this case as 'C' (probably explained), concluding that the sighting was most likely an observation of a conventional aircraft. No additional witnesses came forward to corroborate the sighting, and the description aligns with typical characteristics of aircraft navigation lighting observed under low-light conditions.
02 Timeline of Events
04:30
Initial Detection
Witness observes from home window a single luminous point approaching their position in the pre-dawn sky over Colombes.
04:31
Light Configuration Change
The single point of light transforms into a 'rampe de lumières' (array or ramp of lights) as the object draws closer or changes orientation.
04:32
Rear View Observation
As the object passes and is viewed from behind, witness clearly distinguishes two luminous points displaying green and red coloration, consistent with aircraft navigation lights.
04:33
Object Departs
The luminous phenomenon continues on its trajectory and disappears from view. No sound was heard throughout the observation.

Report Filed
Witness reports the sighting to authorities. No additional witnesses come forward to corroborate the observation.
03 Key Witnesses
Anonymous Witness 1
Civilian resident
medium
Colombes resident who reported the sighting from their home window during early morning hours. Demonstrated observational honesty by acknowledging limitations in what could be perceived.
"Il définit son observation comme tout d'abord un point lumineux s'approchant et devenant une rampe de lumières pour enfin et vu de l'arrière constater deux points lumineux de couleur verte et rouge."
04 Analyst Notes -- AI Processed
This case presents classic indicators of aircraft misidentification during pre-dawn hours. The witness's description follows a logical pattern consistent with viewing an aircraft at different angles: a single approaching light (likely a landing light or forward navigation light), expanding to multiple lights as the aircraft's profile becomes visible, and finally resolving into the standard green (starboard) and red (port) navigation lights when viewed from behind. The 4:30 AM timeframe places this observation during a period of active air traffic approaching Paris airports, particularly Charles de Gaulle and Orly. The credibility factors are mixed but lean toward reliable identification. The single-witness account lacks corroboration, which is common for early morning sightings in residential areas. However, the witness's honest admission of being unable to see a clear shape or hear distinctive sounds demonstrates observational integrity rather than embellishment. The location of Colombes, situated approximately 10 kilometers northwest of central Paris and directly under approach corridors for major airports, makes conventional aircraft traffic the overwhelming probability. GEIPAN's 'C' classification reflects appropriate confidence in this prosaic explanation.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Perceptual Misinterpretation During Low-Light Conditions
A single witness observing unfamiliar aerial phenomena during pre-dawn darkness, when contextual cues are minimal and depth perception is compromised, is highly susceptible to misidentifying conventional aircraft. The witness's inability to discern shape or hear sound, combined with the textbook description of aircraft lighting as viewed from multiple angles, makes this an archetypal case of prosaic aerial phenomenon misidentification. The lack of corroborating witnesses further suggests nothing anomalous occurred.
06 Verdict
ANALYST VERDICT
This case is almost certainly a misidentification of a conventional aircraft on approach to or departing from one of the Paris metropolitan airports. The witness's description perfectly matches the changing appearance of aircraft navigation lights when viewed from different angles: forward-facing lights appearing as a bright point, the aircraft's full lighting array when broadside, and the standard red/green navigation lights when departing. The 4:30 AM timing, the location under busy air corridors, the silence (aircraft at altitude and distance), and the lack of anomalous behavior all support this conclusion. GEIPAN's 'C' classification is appropriate. This case holds minimal significance for UAP research, serving primarily as an example of how unfamiliarity with aircraft lighting patterns can generate reports, particularly during low-light conditions when contextual cues are limited.
