On February 7, 2013, at approximately 21:45 local time, a witness and his wife observed a slowly moving luminous object in the sky near Bastia, Corsica. The object initially appeared as a slow-moving light source, then transformed into a black cylindrical shape when it changed direction. The witness was not at his usual residence at the time, providing him with an unfamiliar vantage point. The observation occurred approximately 3-4 kilometers from Bastia-Poretta Airport to the northwest.
GEIPAN investigators cross-referenced the sighting time with commercial flight schedules and identified Air Corsica flight from Marseille to Bastia departing at 21:05 and scheduled to land at 21:55. The timing aligned perfectly with the witness observation at 21:45 during the aircraft's approach phase. Weather reports indicated southwesterly winds that day, corresponding to the red approach trajectory shown in airport approach charts for Bastia aerodrome.
What particularly intrigued the witness was the apparently low altitude of the object, which he described as "twice as low as usual aircraft." GEIPAN analysts noted two factors: the witness was observing from an unfamiliar location, potentially affecting his altitude perception, and the pilot may have chosen a lower-than-typical approach altitude for operational reasons specific to that flight. The case received GEIPAN's 'A' classification, indicating positive identification as the Marseille-Bastia flight on landing approach.

04 Analyst Notes -- AI Processed
This case exemplifies the importance of contextual investigation in UFO reports. GEIPAN's methodology demonstrates thoroughness by cross-referencing witness testimony with flight schedules, meteorological data, and airport approach procedures. The witness's description contains classic characteristics of aircraft misidentification: slow movement consistent with landing speed, luminous appearance (landing lights), and cylindrical black shape when viewed from different angles (fuselage becoming visible).
The credibility assessment benefits from the witness's honesty about observing from an unfamiliar location, which affected his frame of reference for typical aircraft altitudes. The perceived anomaly—the unusually low altitude—has rational explanations: altered perspective from a different viewing position and potential pilot discretion in approach altitude. The southwest wind conditions correlating with specific approach trajectories adds independent corroboration. This case serves as an educational example of how ordinary aviation can appear extraordinary when observed under unfamiliar circumstances or viewing angles.

BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Perspective Illusion from Unfamiliar Vantage Point
The witness's own statement that he was not at his usual residence is critical. Observing aircraft from an unfamiliar location fundamentally alters depth perception and altitude assessment. What appeared as 'twice as low' was likely normal approach altitude viewed from a different angle and distance. Combined with twilight conditions at 21:45 affecting visual judgment, this represents classic perceptual misidentification rather than any anomalous phenomenon.
06 Verdict
ANALYST VERDICT
GEIPAN's classification A (fully explained) is well-substantiated and appropriate for this case. The sighting is conclusively identified as Air Corsica flight from Marseille to Bastia during its landing approach. The temporal correlation is precise (21:45 observation during 21:05-21:55 flight window), the location is consistent (3-4km from the airport on the approach path), and the visual description matches an aircraft in landing configuration. The perceived anomaly of low altitude is adequately explained by the witness's unfamiliar observation point and normal variations in pilot approach procedures. This case demonstrates no unexplained phenomena and represents a textbook example of aircraft misidentification due to contextual unfamiliarity rather than any genuine anomaly.
