🇫🇷 GEIPAN / CNES
On September 7, 2015, a witness in Paris heard an unusual noise that was already familiar to her. This sound, recurring irregularly for months, prompted her to investigate around midnight. From her fourth-floor apartment, she observed three fixed silver lights and a flashing red light. The object followed a straight trajectory, passed over the opposite building, and disappeared behind the urban landscape. Although the noise itself was not surprising, the curious detail was that she did not recognize the object as an airplane or helicopter. Despite the high population density, no other witnesses were reported. The GEIPAN classified the case as B, considering it likely a conventional aircraft with unusual characteristics.
