Beautiful blue sky. Birds fly. Rare low clouds against the background of clouds that are distant and filled the entire visible sky. Rare, but incomprehensibly long and light compared to the rest of the sky. This is completely strange... Where in the world could such clouds come from? This clearly does not look like steam produced by a thermal power plant, but it is low for airplanes. Although of course the clouds are serious, the more serious question will be somewhat different: where am I? And who am I?..
