Grey object with tail fins over Coutevroult

Summary

On the night of 20 July 2008, a motorist and a passenger observed a light-grey object with two large tail fins that curved through the sky before disappearing to the west. The witnesses took two photographs with their phone. There were no other testimonies or reported aerial phenomena in the area. The investigation concluded it was most likely an airliner making a sharp turn to line up with the runways at Roissy-Charles de Gaulle airport. The report deemed the event credible, though the lack of corroborating records prevented full confirmation.
