It took ten minutes to weld the new piece into place. In the meantime, the gripper reep returned from dumping the scrap section, and Blair sent Ricks up to the grid to help Dan moor his ship. Ricks and Dan came back carrying two tool kits and, when the welding job was finished, Blair and Ricks stood aside as Dan power-sanded the new weld and did a quick spray-painting that removed the signs of the patch. Straightening, he said, "There you go. Good as new." "Fine," said Blair. "Let's see how the cargo made out." The three men returned to the grid, where they moored Wiley's ship across from Dan's, and then the four of them went on back inside the Station. Mendel was waiting for them inside the lock, brow furrowed with worry. He glanced back and forth from Blair to Ricks, then said to Blair, "How did it go?" "Fine." "Just peachy," said Ricks. "I get my merit badge, don't I, Cargomaster?" Blair shook his head at Mendel, and went on toward the elevator without answering Ricks. He headed immediately for Section Five. Three crewmen were already at the bulkhead, which was still sealed shut. Blair looked at the pressure gauge, and saw that the dial was above the halfway mark and noticeably climbing. He talked with the crewmen a few minutes, discussing the strike and its repairing, and then at last the bulkhead door slid back into its recess, and they went on in. The crewmen went to work on the permanent repair of the inner hull, and Blair checked his cargo. A few of the food cartons had exploded when the section had gone to vacuum, but he gave them hardly a glance. He found the seven aluminum crates for QB. All had split open, releasing interior air, but their contents looked to be still in good condition. Blair grinned to himself with relief. QB was the maintenance base. As such, it had a permanent crew of eighty-four men. These men were on thirty-minute call at all times, and were fulfilling a two-year contract with General Transits. They spent every moment of those two years inside the QB satellite. Most of the time, they had little work to do, but the size of the crew was the statistical minimum required for any foreseeable accident to any part of the General Transits lifeline between the Earth and the Moon. When there was any sort of breakdown, such as this meteor strike on Station One, they went to work. The rest of the time, they were completely on their own. Their world, for two years, was a small metal ring nearly a quarter million miles from home. They couldn't leave it, and they had little to do inside it. That was why the contents of the seven aluminum crates was so important. Four cartons of motion picture film and three cartons of microfilmed books. Six months of entertainment, of distraction. The only way the men of QB could keep from going stir-crazy in their two years of self-imposed imprisonment, the only way to last through the inactive days and weeks between the infrequent calls for their skills and labor.
