Knowing human nature, he fears what the desperate lottery losers might do. As a precaution, he has stockpiled weapons. His fears prove accurate. His much-abused assistant, F, tries to get himself included in the crew at gunpoint, only to be shot dead. During the final night, the selected passengers and animals are quietly moved to the launch pad to protect them from any more violence.
Shortly before takeoff, many of the lottery losers riot, taking up weapons to try and force their way aboard. H stays behind at the last moment, forcibly keeping S from boarding as well in order to lighten the spaceship. With an effort born of desperation, Stanton stands up and starts walking in a futile attempt to board the ship before it takes off.
From space, the ship's television monitor shows Earth's collision with B. H's sacrifice proves to be crucial, as the fuel runs out too soon and R glides the ship to an unpowered rough landing on Z. The passengers debark and find the planet to be hospitable. Remains of an alien civilization are also visible in the distance.
