An account in Yvelines, France

On August 11, 2011, at around 11 p.m., a witness observed from his home the slow, straight-line movement of a luminous point. He filmed the phenomenon before it disappeared behind trees. This witness had already observed the same phenomenon in June 2011. Of low strangeness and good consistency, this observation case resembles in every way a misidentification with an aircraft in its landing phase. However, the relative distance of the observation site from the main airports of the Ile-de-France region, whose approach was most likely from the east that evening, prevents us from classifying it as A. This case is classified as B.
