We learn there that the "flying saucers" would be a simple mirage, because planes seen in the distance resemble dots when seen by "witnesses flying in tight formations [sic]." Flying dots being round, and flying discs being also round, then inevitably...
To excuse the newspaper, let us note their systematic use of the conditional, and let us remember that the article is nothing more than the resumption of an official statement by the Associated Press about some American scientist persuaded to have definitively ended the "flying saucers" nonsense that hit the news a few days ago.

In extreme limits of vision, any object, whatever its real dimensions, ultimately appears in the shape of a more or less luminous point.
When we deal with an object reflecting the light as it is the case in the majority of the phenomena we refer to, the eye almost always sees a tiny circle.
