The quiet Argentinean town of Carmen d'Areco has suddenly revived due to an unusual incident. Locals noticed that three large circles of ideal shape appeared on the runway of the flying club. They are scorched strips of grass.
The mysterious phenomenon attracted the attention of the media and local authorities. The mayor of the city visited the scene. He called the experts of the Commission on UFO Research. Meanwhile, the residents of Carmen de Areco were divided. Some believe that the circles on the grass were left by aliens. Someone thinks that this is just someone's joke. Agronomists say that it is possible to burn out the grass in this way with the help of herbicides. These chemicals kill weeds.
However, experts took samples of the burnt grass. They will be studied at the Faculty of Agronomy of the University of Buenos Aires. Perfectly shaped circles periodically appear in crops in different parts of the world. Their origin is not yet clear. For example, a similar incident happened about three years ago in Germany. Then, in the field of a Bavarian farmer, someone crushed wheat, creating a perfect circle with precise geometric shapes inside.
