Val-d'Oise, France · 2010-01-04 · from the GEIPAN archive
On January 4, 2010 at around 7:45 p.m., a witness out for a walk is intrigued by the east-west movement of a large dark triangular shape with dim yellow-orange glowing circles at each end. The speed is constant and no particular noise is heard during the 10 to 15 seconds of observation. No other witness report will be collected. The investigation confirmed the content of the testimony, clarified it, and lent credibility to the witness's statement. This strange observation, which does not resemble classic misidentifications, is also not compatible with the sighting of a passenger plane passing by, especially since the witness is very accustomed to observing planes. The testimony would be compatible with a model or drone of 2.5 meters in size flying at 150 meters altitude at about 35-150 km/h below the radar cone of air traffic control (CDG); however, it seems very unlikely that this type of craft would fly in an urban area, at night, on a winter evening; this hypothesis, although it could match the observation, was not retained for lack of other conclusive evidence. This strange observation was reported by only one witness, with no photo or video; despite the quality of the testimony, this case remains of medium consistency. GEIPAN classifies this strange and moderately consistent case in category D1, as an unexplained phenomenon.
