On March 24, 1976, the manager of a restaurant on the island of Marie-Galante, Guadeloupe, alerted the gendarmerie to the discovery of two metallic spheres on La Feuillère beach. Upon investigation, authorities confirmed the presence of two semi-buried hemispheres approximately one meter in diameter each, separated by 14 meters, positioned at the water's edge and partially covered by seawater. The objects displayed a brilliant metallic color and were covered with a thin metallic coating approximately 0.5 millimeters thick.
Gendarmerie examination revealed distinctive characteristics: on one hemisphere, the outer coating appeared to have melted, exposing a harder, more resistant underlying metal that could not be scratched with a knife point. The following morning at 06:30, officers excavated the objects and determined they were two hemispheres belonging to the same device, fitting together perfectly. A marking "H 476 AC" was clearly visible on one of the hemispheres, suggesting industrial or aerospace origin. The gendarmerie planned to transport the objects to their station for cleaning and identification.
However, at 10:00 on March 25, the mayor of Capesterre-de-Marie-Galante, defying gendarmerie orders, had the hemispheres removed and displayed in the town square. GEIPAN classified this as a Class B case (likely explained with good data) and explicitly noted it is not a UAP observation but rather the recovery of metallic debris. The official report suggests the origin could potentially be identified through the nomenclature marking found inside one hemisphere.

04 Analyst Notes -- AI Processed
This case represents a physical evidence recovery rather than a UAP sighting, which explains the GEIPAN Class B classification. The presence of the marking "H 476 AC" is highly significant as it suggests an identifiable manufactured object, likely of aerospace or industrial origin. The physical characteristics—two hemispheres designed to fit together, metallic construction with layered composition, and evidence of heat damage (melted outer coating)—are consistent with fuel tanks, pressure vessels, or protective housings from rockets, satellites, or aircraft.
The separation distance of 14 meters between the hemispheres and their location at the waterline suggests they washed ashore, possibly after ocean splashdown or atmospheric re-entry. The period (1976) corresponds to active space programs including Soviet and American launches, and Guadeloupe's Atlantic location makes it plausible for debris from launch trajectories or re-entry corridors. The mayor's interference with the investigation, while problematic from an evidentiary standpoint, indicates local interest but also prevented proper scientific analysis. The case credibility is high due to official gendarmerie documentation and physical evidence with identifying marks.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Industrial or Maritime Equipment
Alternative explanation suggests these could be components from maritime vessels, industrial equipment, or buoys that washed ashore. The marking system could be from commercial or military maritime hardware rather than aerospace. However, this theory is less consistent with the heat damage evidence and the precise fit of the two hemispheres.
06 Verdict
ANALYST VERDICT
This case is most likely explained as recovered aerospace debris, potentially from a rocket fuel tank, satellite component, or pressure vessel. The presence of an identifying marking ("H 476 AC"), the industrial metallic construction with heat damage, and the two-part spherical design all point to manufactured aerospace hardware rather than unexplained phenomena. Confidence level is high. GEIPAN's own assessment correctly identifies this as not a UAP observation but rather material recovery. The case is significant primarily as an example of how physical debris can initially generate UFO reports, and how proper investigation can distinguish manufactured objects from unexplained phenomena. The failure to properly secure and analyze the objects due to municipal interference represents a missed opportunity for definitive identification, though the marking should have been sufficient for tracing the object's origin through aerospace registries.
