Space Platform Part 21

Major Holt said coldly: "Of course I see! It would need only one tank of doctored fuel to be delivered to the airfield, and it need not be used for weeks. And there would be no trace in the wreckage, after the fire!

You are telling me there is one underground storage tank in which the fuel is highly explosive. It is plausible. I will have it checked immediately."

He hung up, and Joe went back to his meal. He felt uneasy. There couldn't be any way to make a jet motor explode unless you fed it explosive fuel. Then there couldn't be any way to stop it. And then--after the wreck had burned--there couldn't be any way to prove it was really sabotage. But the feeling of having reported only a guess was not too satisfying. Joe ate gloomily. He didn't pay much attention to Talley. He had that dogged, uncomfortable feeling a man has when he knows he doesn't qualify as an expert, but feels that he's. .h.i.t on something the experts have missed.

Half an hour after the evening mess--near sunset--a security officer wearing a uniform hunted up Joe at the airfield.

"Major Holt sent me over to bring you back to the Shed," he said politely.

"If you don't mind," said Joe with equal politeness, "I'll check that."

He went to the phone booth in the barracks. He got Major Holt on the wire. And Major Holt hadn't sent anybody to get him.

So Joe stayed in the telephone booth--on orders--while the Major did some fast telephoning. It was comforting to know he had a pistol in his pocket, and it was frustrating not to be allowed to try to capture the fake security officer himself. The idea of murdering Joe had not been given up, and he'd have liked to take part personally in protecting himself. But it was much more important for the fake security man to be captured than for Joe to have the satisfaction of attempting it himself.

As a matter of fact, the fake officer started his getaway the instant Joe went to check on his orders. The officer knew they'd be found faked.

It had not been practical for him to shoot Joe down where he was. There were too many people around for this murderer to have a chance at a getaway.

But he didn't get away, at that. Twenty minutes later, while Joe still waited fretfully in the phone booth, the phone bell rang and Major Holt was again on the wire. And this time Joe was instructed to come back to the Shed. He had exact orders whom to come with, and they had orders which identified them to Joe.

Some eight miles from the airfield--it was just dusk--Joe came upon a wrecked car with motorcycle security guards working on it. They stopped Joe's escort. Joe's phone call had set off an alarm. A plane had spotted this car tearing away from the airfield, and motorcyclists were guided in pursuit by the plane. When it wouldn't stop--when the fake Security officer in it tried to shoot his way clear--the plane strafed him. So he was dead and his car was a wreck, and the motorcycle men were trying to get some useful information from his body and the car.

Joe went to the Major's house in the officers'-quarters area. The Major looked even more tired than before, but he nodded approvingly at Joe.

Sally was there too, and she regarded Joe with a look which was a good deal warmer than her father's.

"You did very well," said the Major detachedly. "I don't have too high an opinion of the brains of anybody your age, Joe. When you are my age, you won't either. But whether you have brains or simply luck, you are turning out to be very useful."

Joe said: "I'm getting security conscious, sir. I want to stay alive."

The Major regarded him with irony.

"I was thinking of the fact that when you worked out the matter of the doctored pushpot fuel, you did not try to be a hero and prove it yourself. You referred it to me. That was the proper procedure. You could have been killed, investigating--it's clear that the saboteurs would be pleased to have a good chance to murder you--and your suspicions might never have reached me. They were correct, by the way.

One storage tank underground was half-full of doctored fuel. Rather more important, another _was_ full, not yet drawn on."

The Major went on, without apparent cordiality: "It seems probable that if this particular sabotage trick had not been detected--it seems likely that on the Platform's take-off, all or most of the pushpots would have been fueled to explode at some time after the Platform was aloft, and before it could possibly get out to s.p.a.ce."

Joe felt queer. The Major was telling him, in effect, that he might have kept the Platform from cras.h.i.+ng on take-off. It was a good but upsetting sensation. It was still more important to Joe that the Platform get out to s.p.a.ce than that he be credited with saving it. And it was not rea.s.suring to hear that it might have been wrecked.

"Your reasoning," added the Major coldly, "was soundly based. It seems certain that there is not one central authority directing all the sabotage against the Platform. There are probably several sabotage organizations, all acting independently and probably hating each other, but all hating the Platform more."

Joe blinked. He hadn't thought of that. It was disheartening.

"It will really be bad," said the Major, "if they ever co-operate!"

"Yes, sir," said Joe.

"But I called you back from the airfield," the Major told him without warmth, "to say that you have done a good job. I have talked to Was.h.i.+ngton. Naturally, you deserve a reward."

"I'm doing all right, sir," said Joe awkwardly. "I want to see the Platform go up and stay up!"

The Major nodded impatiently.

"Naturally! But--ah--one of the men selected and trained for the crew of the Platform has been--ah--taken ill. In strict confidence, because of sabotage it has been determined to close in the Platform and get it aloft at the earliest possible instant, even if its interior arrangements are incomplete. So--ah--in view of your usefulness, I said to Was.h.i.+ngton that I believed the greatest reward you could be offered was--ah--to be trained as an alternate crew member, to take this man's place if he does not recover in time."

The room seemed to reel around Joe. Then he gulped and said: "Yes, sir!

I mean--that's right. I mean, I'd rather have that, than all the money in the world!"

"Very well." The Major turned to leave the room. "You'll stay here, be guarded a good deal more closely than before, and take instructions. But you understand that you are still only an alternate for a crew member!

The odds are definitely against your going!"

"That's--that's all right, sir," said Joe unsteadily. "That's quite all right!"

The Major went out. Joe stood still, trying to realize what all this might mean to him. Then Sally stirred.

"You might say thanks, Joe."

Her eyes were s.h.i.+ning, but she looked proud, too.

"I put it in Dad's head that that was what you'd like better than anything else," she told him. "If I can't go up in the Platform myself--and I can't--I wanted you to. Because I knew you wanted to."

She smiled at him as he tried incoherently to talk. With a quiet maternal patience, she led him out on the porch of her father's house and sat there and listened to him. It was a long time before he realized that she was humoring him. Then he stopped short and looked at her suspiciously. He found that in his enthusiastic gesticulations he had been gesticulating with _her_ hand as well as his own.

"I guess I'm pretty crazy," he said ruefully. "Shooting off my mouth about myself up there in s.p.a.ce.... You're pretty decent to stand me the way I am, Sally."

He paused. Then he said humbly: "I'm plain lucky. But knowing you and--having you like me reasonably much is pretty lucky too!"

She looked at him noncommittally.

He added painfully: "And not only because you spoke to your father and told him just the right thing, either. You're--sort of swell, Sally!"

She let out her breath. Then she grinned at him.

"That's the difference between us, Joe," she told him. "To me, what you just said is the most important thing anybody's said tonight."

The world turned over on its axis with unfailing regularity, and nights followed mornings and mornings followed nights according to well-established precedent. One man turned up in Bootstrap with radiation burns, but he had not offered himself for check over at the hospital. He was found dead in his lodging. Since n.o.body else appeared to have suffered any burns at all, it was a.s.sumed that he was the messenger who had brought the radioactive cobalt to Braun, who also had been doomed by possession of the deadly stuff, but who had broken the chain of fatality by not dumping it free into the air of the Shed. Under the circ.u.mstances, then, three-s.h.i.+ft work on the Platform was resumed, and three times in each twenty-four hours fleets of busses rolled out of Bootstrap carrying men to work in the Shed, and rolled back again loaded with men who had just stopped working there.

Trucks carried materials to the Shed, and swing-up doors opened in the great dome's eastern wall, and the trucks went in and unloaded. Then the trucks went out of the same doors and trundled back for more materials.

In the Shed, s.h.i.+ning plates of metal swung aloft, and welding torches glittered in the maze of joists and upright pipes that still covered the monster shape. Each day it was a little more nearly complete. In a separate, guarded workshop by a sidewall, the Chief and Haney and Mike the midget labored mightily to accomplish the preposterous. They grew lean and red-eyed from fatigue, and short of temper and ever more fanatical--and security men moved about in seeming uselessness but never-ceasing vigilance.

There were changes, though. The a.s.sembly line of pushpots grew shorter, and the remaining monstrosities around the sidewall were plainly near to completion. There came a day, indeed, when only five ungainly objects remained on that line, and even they were completely plated in and needed only a finis.h.i.+ng touch. It was at this time that more crates and parcels arrived from the Kenmore Precision Tool plant, and Joe dropped his schoolroomlike instruction course in s.p.a.ce flight for work of greater immediate need. He and his allies worked twice around the clock to a.s.semble the replaced parts with the repaired elements of the pilot gyros. They grew groggy from the desperate need both for speed and for absolute accuracy, but they put the complex device together, and adjusted it, and surveyed the result through red-rimmed eyes, and were too weary to rejoice.

Then Joe threw a switch and the reconst.i.tuted pilot gyro a.s.sembly began to hum quietly, and the humming rose to a whine, and the whine went deliberately up the scale until it ceased to be audible at all.

Presently a dial announced the impossible, and they gazed at a device that seemed to be doing nothing whatever. The gyros appeared quite motionless. They spun with such incredible precision that it was not possible to detect that they moved a hairbreadth. And the whole complex device looked very simple and useless.
