In April 1561 a strange celestial phenomenon was recorded at dawn in Nuremberg. Witnesses noted hundreds of spheres, cylinders, and other strange objects moving chaotically in the sky. People described it as an aerial battle. It was followed by the appearance of a large black triangular object and then, its crash outside the city.
What could it have been if mankind had no flying machines in those days? A more intelligent life form? This fact is officially documented, the documents are in Switzerland, the city of Zurich.
