"If I flew into Space to other planets..." On summer nights and in winter, in good weather, I like to look at the starry sky. There are so many unexplored planets around that you want to visit. And now my dream has come true! I'm flying into Space. Me and my friends. A few light years pass and we are in another star system. We find a planet where there is life. Getting to know other civilizations. Of course, we can't talk to them. Therefore, we communicate with the help of music that we took with us, the language of sounds is clear to everyone. We filmed everything interesting and new on video cameras and took it home with us to planet Earth.
