Description: According to the newspaper "La voix Du Nord" of March 10, 2002, CEPS, "an association collected documents, such as this photography made by chance which are carefully preserved by the brother of Claude Plessis, Yves, owner of a textile shop in Calais. The negatives of this photograph, expertised, were certified authentic (that does not imply that it is a flying saucer). At the time, the thesis of a sudden apparition of a cloud that dissipated at once did not convince." The newspaper indicates no more detail such as the date or location.
