He grinned at them. The Chief raised his eyebrows. Haney turned his head to stare. Joe said exuberantly: "They've been talking about arming ships with guided missiles to fight with. Too heavy, of course. But--if we could handle guided missiles, why couldn't we handle drones?" The three of them gaped at him. Sally said, startled, "But--but, Joe, I didn't----" "We've got plenty of hulls!" said Joe. Somehow he still looked astonished at what he'd made of Sally's perfectly obvious comment. "Mike's arranged for that! Make--say--six of 'em into drones--space barges. Remote-controlled ships. Control them from one manned ship--the tug! We'll ride that! Take 'em up to the Platform exactly like a tug tows barges. The tow-line will be radio beams. We'll have a space-tow up, and not bother to bring the barges back! There won't be any landing rockets! They'll carry double cargo! That's the answer! A space tug hauling a tow to the Platform!" "But, Joe," insisted Sally, "I didn't think of----" The Chief heaved himself up. Haney's voice cut through what the Chief was about to say. Haney said drily: "Sally, if Joe hadn't kissed you for thinking that up, I would. Makes me feel mighty dumb." Mike swallowed. Then he said loyally, "Yeah. Me too. I'd've made a two-ton cargo possible--maybe. But this adds up. What does the major say?" "I--haven't talked to him. I'd better, right away." Joe grinned. "I wanted to tell you first." The Chief grunted. "Good idea. But hold everything!" He fumbled in his pocket. "The arithmetic is easy enough, Joe. Cut out the crew and air and you save something." He felt in another pocket. "Leave off the landing rockets, and you save plenty more. Count in the cargo you could take anyhow"---- he searched another pocket still----"and you get forty-two tons of cargo per space barge, delivered at the Platform. Six drones--that's 252 tons in one tow! Here!" He'd found what he wanted. It was a handkerchief. He thrust it upon Joe. "Wipe that lipstick off, Joe, before you go talk to the major. He's Sally's father and he might not like it." Joe wiped at his face. Sally, her eyes shining, took the handkerchief from him and finished the job. She displayed that remarkable insensitivity of females in situations productive of both pride and embarrassment. When a girl or a woman is proud, she is never embarrassed. She and Joe went away, and Sally rushed right into her father's office. In fifteen minutes technical men began to arrive for conferences, summoned by telephone. Within forty-five minutes, messengers carried orders out to the Shed floor and stopped the installation of certain types of fittings in all but one of the hulls. In an hour and a half, top technical designers were doing the work of foremen and getting things done without benefit of blueprints. The proposal was beautifully simple to put into practice. Guided-missile control systems were already in mass production. They could simply be adjusted to take care of drones.
