An account in Manche, France

On September 23, 2013 between 8:10 PM and 8:25 PM, a female driver on the D650 between Les Mezières and Saint-Germain-Sur-Ay (beach) is intrigued by two bright points in the sky: one point in particular seems to follow a straight trajectory and moves away at constant speed toward the northwest. The witness clearly identifies an airplane with its condensation trail crossing her field of vision. The witness stops at two locations to take several photographs of the bright point. The testimony and the photos, of very good quality, clearly suggest the observation of an airplane trail, distant, moving away from the witness. When zooming in on the last photos, the bright point turns out to have a flame shape, which is a perspective view of an airplane trail brightly lit by the setting sun (sunset at 7:54 PM). One notes on the reconstructions made with Flightradar24 (attached) that one can find one and even two candidate airplanes that could have caused these trails. (N.B.: the estimate of the witness's observation direction is not precise enough to be sure that these are the airplanes. Moreover, FlightRadar24 only shows civilian airplanes equipped with a certain type of equipment.) See other similar cases on airplane trails. GEIPAN classifies this case "B": very probable observation of airplane condensation trails, at sunset.
