At the end of the fifties, a strange patient was being treated in one of the Moscow hospitals. Doctors could not diagnose him, and meanwhile he was getting worse and worse. But the unusual patient had no right to tell what had happened to him. Mahmud Rafikov was not a member of the security services or a secret scientist. He was a cinematographer, but his name was not indicated in the credits, his films were numbered and not called, and he himself was under a non-disclosure agreement for fifty years. He was the only one filming when Yuri Gagarin landed, he filmed nuclear explosions at close range, and he was lucky enough to survive the release of radioactive elements in a submarine. Korolev and Kurchatov admired his skill. At ninety-one, this only eyewitness remembers every little detail.
