On October 13, 1978, at approximately 20:00 (8:00 PM), two independent witnesses in Troyes and Reims, France—cities approximately 120 kilometers apart in the Grand Est region—reported observing the passage of an elongated object moving through the sky. Both witnesses described colored lights accompanying the object. The sighting occurred at dusk during optimal visibility conditions for observing aerial phenomena.
One of the two witnesses reported a second, similar observation on October 18, 1978, between 19:00 and 20:00 (7:00-8:00 PM), suggesting either a recurring phenomenon or continued air traffic in the area during those evening hours. The consistency of timing (early evening) across both dates is notable.
The official investigation by GEIPAN included consultations with multiple technical authorities. The satellite detection center in Aube department reported no anomalous phenomena for these dates. The technical service of Barberey-Saint-Sulpice aerodrome (near Troyes) informed the gendarmerie that no unusual observations were reported by air traffic personnel on either October 13 or 18. No additional witness testimonies were collected despite the sightings occurring over populated areas.

04 Analyst Notes -- AI Processed
This case receives a GEIPAN Classification B (probable identification), with the official conclusion identifying the observed object as likely an aircraft. Several factors support this assessment: the elongated shape is consistent with conventional aircraft observed at distance or at certain angles; the colored lights match standard aviation lighting (red, green, white navigation lights); the early evening timeframe corresponds with typical commercial and private air traffic patterns; and the repeat observation suggests scheduled air routes rather than anomalous activity.
The credibility of the case is diminished by the lack of corroborating reports. Despite occurring over two major cities (Troyes population ~60,000, Reims ~180,000 in 1978), only two witnesses came forward, and no aviation personnel at the local aerodrome reported anything unusual. The satellite detection center's negative findings eliminate the possibility of a space-related object. The distance between Troyes and Reims (approximately 120km) suggests the witnesses may have observed the same aircraft traveling along a flight corridor connecting these cities, which would be consistent with standard aviation routes in northeastern France. The lack of specific details about altitude, speed, sound, or exact trajectory limits deeper analysis.
05 Theory Comparison
BELIEVER ANALYSIS
Unidentified Aerial Phenomenon
While official sources favor aircraft identification, some anomaly researchers might note that two independent witnesses in separate cities simultaneously reporting an unusual elongated object could suggest something beyond routine air traffic. The colored lights, while consistent with aircraft, could also indicate propulsion systems or other characteristics. The fact that one witness felt compelled to report a second sighting suggests the phenomenon was sufficiently unusual to warrant attention. However, this interpretation is weakened by the complete absence of supporting evidence, technical data, or additional corroboration.
SKEPTIC ANALYSIS
Single Aircraft on Commercial Route
The most parsimonious explanation is a single commercial or private aircraft traveling along a standard flight route connecting or passing between Troyes and Reims. The 120km separation between witnesses and simultaneous timing strongly suggests both observed the same aircraft. The absence of reports from aviation professionals, radar anomalies, or additional witnesses despite populated areas indicates nothing extraordinary occurred. The second sighting five days later at the same time likely represents the same scheduled flight or similar air traffic during peak evening travel hours.
06 Verdict
ANALYST VERDICT
The GEIPAN classification B verdict—probable aircraft identification—appears well-founded based on available evidence. The elongated shape, colored lights, consistent timing across dates, and flight path between two major cities all align with conventional air traffic. The absence of radar anomalies, satellite detection data, or reports from aviation professionals strongly suggests a mundane explanation. The case lacks the extraordinary characteristics that would warrant continued investigation: no unusual maneuvers, no electromagnetic effects, no physical traces, and no credible evidence contradicting the aircraft hypothesis. This represents a typical example of witnesses misidentifying conventional aircraft under evening viewing conditions, possibly enhanced by atmospheric effects or unfamiliar viewing angles. Confidence level: High (85%) that this was conventional aircraft.
