Tom Godwin's story "The Cold Equations" rocked the science fiction world when it appeared. A pilot is on an emergency mission to a planet whose colony is doomed if he doesn't get there. He has just enough fuel to reach the planet - then he finds he has a stowaway, a young girl wanting to be with her brother on the colony. If the pilot jettisons her through the airlock, the ship will barely make it to a landing on the planet. If he does not, the ship will crash and both of them as well as the colony will die. What will he do?
