Green light and drone in Fontenay-le-Fleury

Summary

On January 28, 2018, a witness in Fontenay-le-Fleury (France) observed a very intense green light entering through the living room window. The light formed a kind of rosette and a beam that moved in all directions. The witness, surprised, saw how the object turned on and off several times without making any noise. The phenomenon lasted between 30 and 45 seconds, and after it disappeared, the witness felt relieved. There were no other witnesses or additional evidence.

The GEIPAN investigation concluded that it was most likely a recreational drone with LED lights and a laser. The described features, such as the green color, the beam's mobility, and the lack of noise, match similar drones available online. Although the estimated size suggests a professional drone, the possibility of overestimation by the witness is not ruled out. Ultimately, the case was classified as B, indicating a probable observation of a recreational drone.
