1959-1960
An agreement was finalized between the United States and Canada to institute a joint reporting system of UFOs. The Cirvis/Merint reporting system was created "to extend the early warning coverage for the defence of North America . . . and to extend the reporting of vital intelligence during peacetime." Posters were created to explain that airborne and water-borne objects that appeared hostile, unidentified or that seemed to be acting suspicious, were to be reported immediately. A drawing of a saucer-like object appeared with drawings of missiles and submarines, as examples of hostile objects.
