A radio play based on Kir Bulychev’s story “Gai-do.”
The first version of the story “Gai-do,” titled “Holidays in Space, or Planet Five-four,” was written together with readers of the newspaper “Pioneer Truth.” Children sent Bulychev their suggestions for how the events could unfold, and he chose one of them and wrote a new chapter based on it, which was published in the next issue. Later, the story was rewritten and given a new title.
