French astronomer Pierre Guérin, who died in 2000, was one of the very few scientists who publicly defended UFOs in France. In his book UFOs: the mechanisms of a disinformation (OVNI: Les mécanismes d'une désinformation, 2000), published just before his death, Guérin expressed the opinion that the American policy of UFO secrecy is not near its end, because the revelation of an alien presence would be too great a shock for Mankind.

Dr. Pierre Guérin, senior researcher at the French National Council for Scientific Research (CNRS), has written extensively about the need for scientific research in the UFO field. He was concluding a summary of the UFO evidence published in Sciences & Avenir in 1972. Guérin, P., "Le Dossier des Objets Volants Non Identifiés", Sciences & Avenir, No. 307, Paris, September 1972.
