Cylindrical UFO seen near a house in 2011

Summary

In April 2011, a witness in Léringhem (France) heard a turbine-like noise and observed a black cylindrical object passing very close to his roof. The object, about 80 cm long and 20 to 30 cm wide, was moving in a straight line without emitting light or odor. Although the witness described it several times to the authorities, no plausible explanation was found. Although it was compared to a drone, its model was unknown. The case was classified as D1: unidentified. Although the testimony is unique and brief, its consistency suggests a genuine observation.
