Pilot for Special Assignments. Return of the clipper Krechet

The main characters of Krapivin's books are boys. The author sets them sailing on the stormy seas of life, without making concessions or discounts for their boyish age. The hero had to go through his own path, and everyone has... one. While preserving yourself. Because such qualities as Honor, Courage, Justice never lose their shine, like a sword in a musketeer’s hand.
Fifth-grader Alyoshka appears before us as such a little musketeer in the story “Pilot for Special Assignments.” In search of a lost toy frigate, he finds himself in a wonderful country, in the fabulous city of Vetrogonsk, which has a special Ship Museum, where all the missing ship models are attracted like a magnet. And Antoshka Topolkov, Special Assignments Pilot, delivers him to this amazing city. His job is to fly through protected forests, distant and thirtieth kingdoms and other fabulous territories and provide assistance to people. Difficult work, but very important...
Fourth-grader Vladik Areshkin from the story “The Return of the Krechet Clipper” has two real friends: Gosha, a retired ship gnome, a grumbler and a poet who is writing a poem about the sailing clipper “Krechet”, which he once sailed on. And Tilka, a cheerful glass boy who loves puddles and rain, and so that the rain does not become sad and monotonous, he, together with his friends, transparent little people like him, dances among the flying raindrops to the sounds of flutes, violins and drums.
This story is about the victory of life over death, a victory that is only possible when the sense of responsibility and friendship is stronger than fear and the desire to withdraw into oneself.
