Five small “technical” tales made up this book: “The Tale of a Submarine”, “The Tale of a Small Airplane”, “The Tale of One Tractor”, “The Tale of a Small Truck”, “The Tale of Two Tractors”. It would seem like a dry list of vehicles. But behind each of these names is a truly interesting, simply and clearly told life story, in which small, modest “characters” work conscientiously, fulfill their duty, perform heroic deeds, learn not to make mistakes, understand and respect others. The child, as it were, penetrates into the world of revived technology, begins to love and appreciate it, and at the same time receives lessons in courage, dedication, and the ability to feel needed and useful in life.
