On February 11, 2012, at approximately 23:10 local time, multiple professional observers across the Caribbean witnessed a bright green luminous phenomenon traverse the sky from east to west. The primary witness was an air traffic controller at Martinique Aimé Césaire International Airport in Lamentin, who reported the sighting along with colleagues in the control tower. The observation was corroborated by air traffic controllers in Guadeloupe (a separate island approximately 120km north), ground-based gendarmes (French military police), and the pilots of Air France flight AFR 3570 on the Paris-Martinique route, who witnessed the phenomenon from their aircraft. The object was described as a very bright green ball of light that crossed the Antillean sky rapidly in just a few seconds. The consistent description across multiple independent witnesses separated by significant distances, combined with the characteristic green coloration and east-to-west trajectory, provided strong evidence for the phenomenon's nature. The event occurred during late evening hours when visibility was good, allowing for clear observation by both ground-based and airborne witnesses. GEIPAN (the French government's official UFO investigation service operated by CNES, the French space agency) conducted a thorough investigation and assigned this case a 'B' classification, indicating a probable identification with a high degree of certainty. The investigation took into account the observed characteristics, duration, trajectory, and multiple corroborating witness reports from professional observers.

04 Analyst Notes -- AI Processed
This case demonstrates exceptional witness credibility due to the professional backgrounds of all observers: air traffic controllers trained in identifying aerial phenomena, military police officers, and commercial airline pilots. The geographic distribution of witnesses across multiple Caribbean islands (Martinique and Guadeloupe) rules out localized atmospheric or optical effects. The consistency of descriptions—particularly the distinctive green coloration, rapid transit time of seconds, and east-to-west trajectory—strongly supports a single phenomenon rather than multiple unrelated events. The green coloration is particularly diagnostic, as it indicates the presence of magnesium and nickel burning during atmospheric entry, commonly observed in meteoroid ablation. The reported duration of 'a few seconds' is consistent with a meteoroid rather than space debris, which typically exhibits slower velocities (approximately 7 km/s) and longer transit times (20 seconds to several minutes) as noted in the GEIPAN analysis. The east-to-west trajectory matches typical meteoroid entry vectors. No sonic boom was reported, which could indicate either that the object fragmented at high altitude or that witnesses were beyond the audible range of any acoustic signature.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Corroborated Natural Phenomenon with No Anomalous Characteristics
From a skeptical analytical perspective, this case represents a textbook example of proper witness testimony converging on a mundane explanation. The multi-witness, multi-location observations from trained professionals eliminate misidentification, psychological factors, or localized phenomena. The physical characteristics (green color, trajectory, duration, brightness) all have prosaic scientific explanations within known physics. No aspect of this sighting suggests anything other than natural celestial mechanics.
06 Verdict
ANALYST VERDICT
GEIPAN's assessment of atmospheric meteoroid entry is well-founded and represents the most parsimonious explanation for all observed characteristics. The combination of professional multi-witness testimony, consistent physical descriptions, characteristic green coloration indicative of magnesium combustion, rapid transit time, and ballistic trajectory all align perfectly with a bolide/fireball meteor event. The 'B' classification (probable identification) is appropriate given the high-quality witness testimony and the absence of recovered physical evidence that would elevate it to 'A' (certain identification). This case is significant not for unexplained phenomena, but as an exemplar of proper investigation methodology: multiple independent professional witnesses, consistent phenomenological descriptions, and scientifically rigorous analysis leading to a high-confidence conclusion. The event posed no aviation safety concerns and represents a natural celestial phenomenon.
