The pilot flushes them to the surface of the craft, but not before one bites him, giving him an incurable fatal disease. He returns to Earth to warn them, but he cannot land because the creatures on the hull still live despite his efforts to kill them, and he cannot radio because the aliens could use the signal to arrive on Earth. He goes into orbit around Earth, refusing to respond to hailing frequencies, and this spooks the authorities so they launch a missile at him. Before the missile strikes, he jettisons his log in an escape pod. Once the people of Earth read his log, they realize he was a hero.
