An account in Essonne, France

On April 9, 2011 at around 10:45 p.m., two witnesses in a car very quickly notice white lights seeming to come from a dark object moving very close to the roof of a neighboring house. The group of lights appears close and moves very slowly, with no perceptible noise from inside the vehicle. The lights disappear behind the roof. The witnesses, having gotten out of the car, try to find it again, in vain. Many hypotheses are compatible with this observation case: airplanes, helicopters, Thai lanterns (although these are rather known to be yellow, orange, or red in color); only the atmospheric re-entry of a meteoroid or space debris, as well as a satellite pass, can be ruled out. Of low consistency and low strangeness, this observation case cannot be clearly concluded. The Thai lantern hypothesis could fit well if the witness had noted yellow or orange lights. This case is classified as C due to the imprecision of the testimony.
