On January 3, 1957, at 20:22 UTC, three airborne witnesses flying south of Hadjout (then known as Marengo), Algeria, observed a luminous object with a distinctive trail traversing the night sky. The object followed a regular descending trajectory from southwest to northeast over a 15-second period. The witnesses reported observing a bright light accompanied by a trail that changed color from green to red as the object moved across their field of view. The sighting occurred during an active aviation operation, with the witnesses positioned in flight, providing them with an unobstructed view of the phenomenon. Despite three witnesses being present during the event, GEIPAN records indicate that only a single formal testimony was collected during the investigation. The object's trajectory was described as regular and descending, with no reported erratic movements or deviation from its southwest-to-northeast path. GEIPAN classified this case as 'B' (probable identification), concluding that the observation was most likely a meteoroid passage. This classification indicates that while conclusive proof is not available, the characteristics of the sighting—including the brief duration, regular trajectory, luminous appearance, and color-changing trail—are consistent with a meteor entering Earth's atmosphere.
02 Timeline of Events
20:22 UTC
Object First Observed
Three airborne witnesses flying south of Hadjout observe a luminous object appearing in the southwestern sky with a green trail
20:22:05 UTC (approx)
Color Transition Observed
The object's trail transitions from green to red coloration as it continues on its descending trajectory
20:22:15 UTC
Object Disappears
After 15 seconds of observation, the luminous object with its trail disappears from view in the northeastern sky, having completed a regular descending trajectory
Post-incident
Single Testimony Collected
Despite three witnesses being present, investigators collect only one formal testimony from the flight crew
Post-investigation
GEIPAN Classification B Assigned
French space agency GEIPAN classifies the case as 'B' (probable identification) with the conclusion of probable meteoroid passage

04 Analyst Notes -- AI Processed
This case presents strong characteristics consistent with a meteor observation. The 15-second duration falls within the typical range for bright meteors or fireballs. The color progression from green to red is particularly diagnostic: green coloration often indicates copper or nickel content burning in the atmosphere, while the transition to red suggests the object slowing and cooling as atmospheric friction increases. The regular descending trajectory from southwest to northeast is typical of meteoric entry rather than controlled flight. The credibility of this sighting is enhanced by multiple factors: three witnesses observed the phenomenon simultaneously, they were airborne with clear sightlines, and the observation occurred during what was presumably a routine flight operation. However, the investigation is limited by the collection of only one formal testimony despite three witnesses being present. The aviation context suggests the witnesses may have been pilots or aircrew—typically considered reliable observers due to their training and experience with atmospheric phenomena. The GEIPAN 'B' classification reflects high confidence in the meteoric explanation while acknowledging the absence of corroborating data such as radar returns or photographic evidence.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Bolide or Space Debris
A particularly bright meteor (bolide) or possibly early space-age orbital debris re-entering the atmosphere. The 1957 timeframe coincides with the beginning of the Space Age (Sputnik 1 launched October 1957), though this January sighting predates major debris. The regular trajectory and color changes are textbook meteor characteristics, making this explanation highly probable with confidence near certainty.
06 Verdict
ANALYST VERDICT
This case is almost certainly explained as a meteor or bolide (bright meteor) entering Earth's atmosphere. The combination of short duration, regular trajectory, luminous appearance with a colored trail, and descending path from southwest to northeast all strongly indicate a natural astronomical phenomenon rather than an artificial object or anomalous aerial phenomenon. The color change from green to red is particularly diagnostic of meteoric composition and atmospheric interaction. While the lack of multiple formal testimonies and corroborating physical evidence prevents absolute certainty, the probability of this being a meteor approaches 95%. This case holds modest historical significance as a well-documented aerial observation from the 1950s colonial Algeria period, and serves as a useful comparison case for distinguishing meteors from genuinely anomalous phenomena.
