"It's really the other way about, sir," objected Joe. "The Chief and Haney are pretty good, and Mike's got brains―"
The Major moved impatiently.
"I am looking at this from a security standpoint," he said. "I am trying to make it plainly useless to attack the gyros again. Duplicates will be in production at your father's plant. There will be three men repairing the smashed ones. There will be another man in another place—and this will be you—who can instruct new workmen in the repair procedure if anything should happen. Thus there will have to be three separate successful coups if the pilot gyros are not to be ready when the Platform needs them. Saboteurs might try one. Possibly two. But I think they will look for another weak spot to attack."
Joe did not like the idea of being moved away. He wanted to be on the job repairing the device that was primarily his responsibility. Besides, he had a feeling about Sally. If she were in danger, he wanted to be on hand.
"About Sally, sir―"
"Sally," said the Major tiredly, "is going to have to restrict herself to the point where she'll feel that jail would be preferable. But she will see the need for it. She will be guarded a good deal more carefully than before—and you may not know it, but she has been guarded rather well."
Joe saw Sally smiling ruefully at him. What the Major had said was unpleasant, but he was right. This was one of those arrangements that nobody likes, an irritating, uncomfortable, disappointing necessity. But such necessities are a part of every actual achievement. The difference between things that get done and things that don't get done is often merely the difference between patience and impatience with tedious details. This arrangement would mean that Joe couldn't see Sally very often. It would mean that the Chief and Haney and Mike would do the actual work of getting the gyros ready. It would take all the glamour out of Joe's contribution. These deprivations shouldn't be necessary. But they were.
"All right, sir," said Joe gloomily. "When do I go over to the field?"
"Right away," said the Major. "Tonight." Then he added detachedly: "Officially, the excuse for your presence there will be that you have been useful in uncovering sabotage methods. You have. After all, through you a number of planes that would have been blown up have now had their booby traps removed. I know you do not claim credit for the fact, but it is an excuse for keeping you where I want you to be for another reason entirely. So it will be assumed that you are at the pushpot field for counter–sabotage inspection."
The Major nodded dismissal with an indefinable air of irony, and Joe went unhappily out of his office. He telephoned his father at length. His father did not share Joe's disappointment at being removed to a place of safety. He undertook to begin the castings for an entire new set of pilot gyros at once.
A little later Sally came out of her father's office.
"I'm sorry, Joe!"
He grinned unhappily.
"So am I. I don't feel very heroic, but if this is what has to be done to get the Platform out of the Shed and on the way up—it's what has to be done. I suppose I can phone you?"
"You can," said Sally. "And you'd better!"
They had talked a long time that afternoon, very satisfyingly and without any cares at all. Neither could have remembered much of what had been said. It probably was not earth–shaking in importance. But now there seemed to be a very great deal of other similar conversation urgently needing to be gone through.
"I'll call you!" said Joe.
Then somebody approached to take him to the pushpot airfield. They separated very formally under the eyes of the impersonal security officer who would drive Joe to his destination.
It was a tedious journey through the darkness. This particular security officer was not companionable. He was one of those conscientious people who think that if they keep their mouths shut it will make up for their inability to keep their eyes open. Socially he treated Joe as if he were a highly suspect person. It could be guessed that he treated everybody that way.
Joe went to sleep in the car.
He was only half–awake when he arrived, and he didn't bother to rouse himself completely when he was shown to a cubbyhole in the officers' barracks. He went to bed, making a half–conscious note to buy himself some clothes—especially fresh linen—in the morning.
Then he knew nothing until he was awaked in the early morning by what sounded exactly like the crack of doom.

It was not, however, the crack of doom. When Joe stared out the window by the head of his cot, he saw gray–red dawn breaking over the landing field. There were low, featureless structures silhouetted against the sunrise. As the crimson light grew brighter, Joe realized that the angular shapes were hangars. Improbable crane poles loomed above them. One was in motion, handling something he could not make out, but the noise that had awakened him was less, now. It seemed to circle overhead, and it had an angry, droning, buzzing quality that was not natural in any motor he had ever heard before.
Joe shivered, standing at the window. It was cold and dank in the dawn light at this altitude, but he wanted to know what that completely unbelievable roar had been. A crane beam by the hangars tilted down, slowly, and then lifted as if released of a great weight. The light was growing slowly brighter. Joe saw something on the ground. Rather, it was not quite on the ground. It rested on something on the ground.
Suddenly that unholy uproar began again. Something moved. It ran heavily out from the masking dark of the hangars. It picked up speed. It acquired a reasonable velocity—forty or fifty miles an hour. As it scuttled over the dimly lighted field, it made a din like all the boiler factories in the world and all the backfiring motors in creation trying to drown each other's noise out—and all of them being very successful.
It was a pushpot. Joe recognized it with incredulity. It was one of those utterly ungainly creations that were built around one half of the sidewall of the Shed. In shape, its upper part was like the top half of a loaf of bread. In motion, here, it rested on some sort of wheeled vehicle, and it was reared up like an indignant caterpillar, and a blue–white flame squirted out of its tail, with coy and frolicsome flirtings from side to side.
The pushpot lifted from the vehicle on which it rode, and the vehicle put on speed and got away from under it with frantic agility. The vehicle swerved to one side, and Joe stared with amazed eyes at the pushpot, some twenty feet aloft. It had a flat underside, and a topside that still looked to him like the rounded top half of a loaf of baker's bread. It hung in the air at an angle of about forty–five degrees, and it howled like a panic–stricken dragon—Joe was getting his metaphors mixed by this time—and it swung and wobbled and slowly gained altitude, and then suddenly it seemed to get the knack of what it was supposed to do. It started to circle around, and then it began abruptly to climb skyward. Until it began to climb it looked heavy and clumsy and wholly unimpressive. But when it climbed, it really moved!
Joe found his head out the window, craning up to look at it. Its unearthly din took on the indignant quality of an irritated beehive. But it climbed! It went up without grace but with astonishing speed. And it was huge, but it became lost in the red–flecked dawn sky while Joe still gaped.
Joe flung on his clothes. He went out the door through resonant empty corridors, hunting for somebody to tell him something. He blundered into a mess hall. There were many tables, but the chairs around them were pushed back as if used and then left behind by people in a hurry to be somewhere else. There were exactly two people still visible over in a corner.
