"I want to boot you in the rump, Irv, I swear." Mendel grinned. "I feel like doing some rump-booting myself. Take it easy, Glenn. It'll all work out." "Hot diggity," said Blair sourly. "Want to come up to the office with me?" "No." "Suit yourself." Mendel left, and Blair stomped angrily back down the corridor to Section Two, where he found the three engineers still waiting by the elevator. He glared at them and snarled, "What the devil are you clowns doing? Get out of those idiot clown suits, the party's over." The three of them stared at him in astonishment. Ricks looked as though he might smart-talk, and Blair waited hopefully, fists clenched, but something about his stance gave Ricks second thoughts and he turned away without a word, red-faced and frowning. * * * * * QB was the Quartermaster Base, a large satellite in permanent orbit two hundred miles above the surface of the Moon. It was shaped somewhat like the three Space Stations, though with a thicker outer ring and a less intricate inner section. This base held all of the equipment for maintenance and repair of the entire General Transit system, the three Space Stations, the two barbells, and the Moon-based lighters. Attached to QB by a simple hook-and-ring mechanism were six repair ships, familiarly known as Reeps. Reeps were small blunt rounded one-man ships, with payloads made up exclusively of fuel. Protruding from the front of each reep were four jointed arms, operated by the arms and legs of the pilot. The reep had one large rocket exhaust at the rear, which swiveled to allow turning maneuverability, and four small swivelled exhausts around the body, permitting the reep complete close-range maneuverability. An experienced reep pilot could operate his ship as though it were an extension of his body, backing and sidestepping, working the four arms as readily as he used his own arms and legs. There were two kinds of reeps, and three of each kind. There was the gripper reep, with arms designed for holding and manipulating, and the fixer reep, with arms for welding and cutting. When the call came in from Station One, QB was three-quarters around the Earth-side of its orbit. The radioman on duty got the approximate dimensions of the meteor now jammed into the outer edge of the Station, and its approximate placement, and passed this information on to the Dispatcher Office. A call then went down to the Supply Department for Part X-102-W, outer hull replacement panel. This piece, eight feet by eight, was delivered to the Dispatch Delivery Point, at the inner rim of the doughnut. Meanwhile, fixer reep 2 and gripper reep 5 were fueled and piloted. Spacesuited QB crewmen put the replacement panel in position for the gripper reep to get hold of, and the two ships broke away from the satellite, headed toward Earth.
