LONRAI (61) 02.02.2012

On 2 February 2012 at 00:45, several people at Lonrai heard a loud, dull sound and saw a dark, unlit mass moving slowly at low altitude. The sound seemed to come from it; the source summary places the sound before the visual observation. GEIPAN considers the main account consistent with a relatively conventional powered aircraft flying without lights: perhaps an unauthorized flight by an airship, microlight or possibly a helicopter, or a military exercise. The investigation report provides details. GEIPAN classifies the case B: a probable unlit aircraft.
