Space Platform by Murray Leinster (miss read books .txt) 📗

nation could possibly defy. And so this Space Platform would keep peace on Earth.

But it could not make good will among men.

Sally walked on. They reached the mysterious objects being manufactured in a row around half the sidewall of the Shed. They were of simple design and, by comparison, not unduly large. The first objects were merely frameworks of metal pipe, which men were welding together unbreakably. They were no bigger than—say—half of a six-room house. A little way on, these were filled with intricate arrays of tanks and piping, and still farther—there was a truck and hoist unloading a massive object into place right now—there were huge engines fitting precisely into openings designed to hold them. Others were being plated in with metallic skins.

At the very end of this assembly line a crane was loading a finished object onto a flat-bed trailer. As it swung in the air, Joe realized what it was. It might be called a jet plane,[Pg 44] but it was not of any type ever before used. More than anything else, it looked like a beetle. It would not be really useful for anything but its function at the end of Operation Stepladder. Then hundreds of these ungainly objects would cluster upon the Platform’s sides, like swarming bees. They would thrust savagely up with their separate jet engines. They would lift the Platform from the foundation on which it had been built. Tugging, straining, panting, they would get it out of the Shed. But their work would not end there. Holding it aloft, they would start it eastward, lifting effortfully. They would carry it as far and as high and as fast as their straining engines could work. Then there would be one last surge of fierce thrusting with oversize jato rockets, built separately into each pushpot, all firing at once.

Finally the clumsy things would drop off and come bumbling back home, while the Platform’s own rockets flared out their mile-long flames—and it headed up for emptiness.

But the making of these pushpots and all the other multitudinous activities of the Shed would have no meaning if the contents of four crates in the wreckage of a burned-out plane could not be salvaged and put to use again.

Joe said restlessly: “I want to see all this, Sally, and maybe anything else I do is useless, but I’ve got to find out what happened to the gyros I was bringing here!”

Sally said nothing. She turned, and they moved across the long, long space of wood-block flooring toward the doorway by which they had entered. And now that he had seen the Space Platform, all of Joe’s feeling of guilt and despondency came back. It seemed unbearable. They went out through the guarded door, Sally surrendered the pass, and Joe was again checked carefully before he was free to go.

Then Sally said: “You don’t want me tagging around, do you?”

Joe said honestly: “It isn’t exactly that, Sally, but if the stuff is really smashed, I’d—rather not have anybody see me. Please don’t be angry, but—”

Sally said quietly: “I know. I’ll get somebody to drive you over.”

She vanished. She came back with the uniformed man [Pg 45]who’d driven Major Holt. She put her hand momentarily on Joe’s arm.

“If it’s really bad, Joe, tell me. You won’t let yourself cry, but I’ll cry for you.” She searched his eyes. “Really, Joe!”

He grinned feebly and went out to the car.

The feeling on the way to the airfield was not a good one. It was twenty-odd miles from the Shed, but Joe dreaded what he was going to see. The black car burned up the road. It turned to the right off the white highway, onto the curved short cut—and there was the field.

And there was the wreck of the transport plane, still where it had crashed and burned. There were still armed guards about it, but men were working on the wreck, cutting it apart with torches. Already some of it was dissected.

Joe went to the remains of the four crates.

The largest was bent askew by the force of the crash or an explosion, Joe didn’t know which. The smallest was a twisted mass of charcoal. Joe gulped, and dug into them with borrowed tools.

The pilot gyros of the Space Platform would apply the torque that would make the main gyros shift it to any desired position, or else hold it absolutely still. They were to act, in a sense, as a sort of steering engine on the take-off and keep a useful function out in space. If a star photograph was to be made, it was essential that the Platform hold absolutely still while the exposure lasted. If a guided missile was to be launched, it must be started right, and the pilot gyros were needed. To turn to receive an arriving rocket from Earth....

The pilot gyros were the steering apparatus of the Space Platform. They had to be more than adequate. They had to be perfect! On the take-off alone, they were starkly necessary. The Platform couldn’t hope to reach its orbit without them.

Joe chipped away charred planks. He pulled off flame-eaten timbers. He peeled off carbonized wrappings—but some did not need to be peeled: they crumbled at a touch—and in twenty minutes he knew the whole story. The rotor motors were ruined. The couplers—pilot-to-main-gyro connections—had [Pg 46]been heated red hot and were no longer hardened steel; their dimensions had changed and they would no longer fit. But these were not disastrous items. They were serious, but not tragic.

The tragedy was the gyros themselves. On their absolute precision and utterly perfect balance the whole working of the Platform would depend. And the rotors were gashed in one place, and the shafts were bent. Being bent and nicked, the precision of the apparatus was destroyed. Its precision lost, the whole device was useless. And it had taken four months’ work merely to get it perfectly balanced!

It had been the most accurate piece of machine work ever done on Earth. It was balanced to a microgram—to a millionth of the combined weight of three aspirin tablets. It would revolve at 40,000 revolutions per minute. It had to balance perfectly or it would vibrate intolerably. If it vibrated at all it would shake itself to pieces, or, failing that, send aging sound waves through all the Platform’s substance. If it vibrated by the least fraction of a ten-thousandth of an inch, it would wear, and vibrate more strongly, and destroy itself and possibly the Platform. It needed the precision of an astronomical telescope’s lenses—multiplied! And it was bent. It was exactly as useless as if it had never been made at all.

Joe felt as a man might feel if the mirror of the greatest telescope on earth, in his care, had been smashed. As if the most priceless picture in the world, in his charge, had been burned. But he felt worse. Whether it was his fault or not—and it wasn’t—it was destroyed.

A truck rolled up and was stopped by a guard. There was talk, and the guard let it through. A small crane lift came over from the hangars. Its normal use was the lifting of plane motors in and out of their nacelles. Now it was to pick up the useless pieces of equipment on which the best workmen and the best brains of the Kenmore Precision Tool Company had worked unceasingly for eight calendar months, and which now was junk.

Joe watched, numbed by disaster, while the crane hook [Pg 47]went down to position above the once-precious objects. Men shored up the heavy things and ran planks under them, and then deftly fitted rope slings for them to be lifted by. It was late afternoon by now. Long shadows were slanting as the crane truck’s gears whined, and the slack took up, and the first of the four charred objects lifted and swung, spinning slowly, to the truck that had come from the Shed.

Joe froze, watching. He watched the second. The third did not spin. It merely swayed. But the fourth.... The lines up to the crane hook were twisted. As the largest of the four crates lifted from its bed, it twisted the lines toward straightness. It spun. It spun more and more rapidly, and then more and more slowly, and stopped, and began to spin back.

Then Joe caught his breath. It seemed that he hadn’t breathed in minutes. The big crate wasn’t balanced. It was spinning. It wasn’t vibrating. It spun around its own center of gravity, unerringly revealed by its flexible suspension.

He watched until it was dropped into the truck. Then he went stiffly over to the driver of the car that had brought him.

“Everything’s all right,” he said, feeling a queer astonishment at his own words. “I’m going to ride back to the Shed with the stuff I brought. It’s not hurt too much. I’ll be able to fix it with a man or two I can pick up out here. But I don’t want anything else to happen to it!”

So he rode back out to the Shed on the tailboard of the truck that carried the crates. The sun set as he rode. He was smudged and disheveled. The reek of charred wood and burnt insulation and scorched wrappings was strong in his nostrils. But he felt very much inclined to sing.

It occurred to Joe that he should have sent Sally a message that she didn’t need to cry as a substitute for him. He felt swell! He knew how to do the job that would let the Space Platform take off! He’d tell her, first chance.

It was very good to be alive.

There was nobody in the world to whom the Space Platform was meaningless. To Joe and a great many people like him, it was a dream long and stubbornly held to and now doggedly being made a reality. To some it was the prospect of peace and the hope of a quiet life: children and grandchildren and a serene look forward to the future. Some people prayed yearningly for its success, though they could have no other share in its making. And of course there were those men who had gotten into power and could not stay there without ruthlessness. They knew what the Platform would mean to their kind. For, once world peace was certain, they would be killed by the people they ruled over. So they sent grubby, desperate men to wreck it at any cost. They were prepared to pay for or to commit any crime if the Space Platform could be smashed and turmoil kept as the norm of life on Earth.

And there were the people who were actually doing the building.

Joe rode a bus into Bootstrap that night with some of them. The middle shift—two to ten o’clock—was off. Fleets of busses rolled out from the small town twenty miles away, their headlights making a procession of paired flames in the darkness. They rolled into the unloading area and disgorged the late shift—ten to six—to be processed by security and admitted to the Shed. Then, quite empty, the busses went trundling around to where Joe waited with the released shift milling around him.

The busses stopped and opened their doors. The waiting men stormed in, shoving zestfully, calling to each other, scrambling for seats or merely letting themselves be pushed on board. The bus Joe found himself on was jammed in seconds. [Pg 49]He held on to a strap and didn’t notice. He was absorbed in the rapt contemplation of his idea for the repair of the pilot gyros. The motors could be replaced easily enough. The foundation of his first despair had been the belief that everything could be managed but one thing; that the all-important absolute accuracy was the only thing that couldn’t be achieved. Getting that accuracy, back at the plant, had consumed four months of time. Each of the gyros was four feet in diameter and weighed five hundred pounds. Each spun at 40,000 r.p.m. It had to be machined from a special steel to assure that it would not fly to pieces from sheer centrifugal force. Each was plated with iridium lest a speck of rust form and throw it off balance. If the shaft and bearings were not centered exactly at the center of gravity of the rotors—five hundred pounds of steel off balance at 40,000 r.p.m. could raise the devil. They could literally wreck the Platform itself. And “exactly at the center of gravity” meant exactly. There could be no error by which the shaft was off center by the thousandth of an inch, or a ten-thousandth, or even the tenth of a ten-thousandth. The accuracy had to be absolute.

Gloating over the solution he’d found, Joe could have hugged himself. Hanging to a strap in
