Jean-Charles Duboc

Captain Jean-Charles Duboc was, on 28 January 1994, the commander of Air France flight 3532 Nice–London, during which — at 350 knots, together with his co-pilot Valerie Chauffour — he observed an approximately 230-metre-long dark object that, after around one minute, vanished instantaneously. Radar data from the CODA system confirmed the sighting, and the French SEPRA agency classified the case as "Type D" — genuinely unexplained.

For the UAP timeline, Duboc is the French civil-aviation reference case of the 1990s — one of the few sightings where a state body officially classified the case as "unexplained". Together with COMETA, this file forms the French heavyweight in the European UAP debate.
