An account in Vendée, France

On July 1, 2017 at 10:14 PM, several witnesses observe an object leaving orange trails in the clear sky. The witness films his observation. He is then surprised to see other objects leaving orange trails behind them. The trajectories are different. No noise is heard during the observation. The witness thinks of space debris entering the atmosphere. Only one testimony is collected. The video shows without ambiguity an airplane trail. What surprises the witness most is the orange and short trail. It is orange because lit by the setting sun (which still illuminates at the airplane's altitude), the length and persistence depend on many factors that can also mean the trail does not exist at all. To a lesser degree, he is surprised by the speed, 5 times faster than a commercial airliner. A witness can only speak of angular speed, and this is highly variable: stronger at the vertical than at the horizon, at low flight altitude than at high altitude. The video does not give the impression of an exceptional speed. It is verified that many commercial airliners are flying in this sky at that time. GEIPAN will not conduct further investigation since the appearance is indeed that of an airplane. GEIPAN classifies the case as A: airplane.
