 Where was the space craft heading in the end?
Sometimes there's no reason but them for sending a ship back with a crew instead of in an economy orbit. Under a portable, double-chambered plastic dome blown up outside the ship's airlock, a crewman helped him load two trunks and a collection of bags into the tractor. They found they could send back loaded ships by 'automatic' flight—that is, a long, slow, economical orbit and automatic signalling equipment. "I'm retiring in six months if I'm still alive," he said bravely, edging the tractor into the airlock at their destination. In the gravity of Ganymede, the man was knocked off balance as much as he was hurt, and sprawled on the floor.
