CHAPTER XV
The Open Hatchway

Pegasus was ready.

The dry run was over and only the final checkout remained.

At zero minus sixteen hours Rick stood at the base of the huge rocket and looked up, studying every inch of it. He knew he would never have the opportunity again.

About fifty feet up he could make out the smooth, stainless-steel connecting ring where the second stage joined the first. Explosive bolts, set off by one of the electronic circuits, would blow the stages apart. The second stage, still carrying the final stage, would accelerate away on its own motors until they, too, had consumed all available fuel. Again, explosive bolts would destroy the connection and the final stage would be on its own. The motors would flare briefly, providing less than a minute's acceleration, then the final stage would coast on its momentum to maximum altitude nearly three hundred miles above the earth.

Not until the final stage started its downward plunge would Jerry Lipton take over. His job, then, would be to control the plunging flight, to use up the excess of energy by maneuvering the rocket into the atmosphere and out, to prevent its burning up like a meteor. In slow, careful stages, he would let it come lower and lower, until most of its energy was used up. Then he would try to land it. The landing speed would be terrific – nearly a thousand miles an hour.

Gee-Gee Gould came up and stood beside him. "It's a beautiful thing, Rick. And it's ours. Yours, mine, Dick's, Frank's, Charlie's – it belongs to every one of the crew."

Rick knew. It was his rocket. If it worked, it would be because of the care and devotion with which he had done his job. He knew others felt the same, and they were equally right. All of them had built part of themselves into Pegasus.

If it worked.. Of course it would work! He sought reassurance from Gee-Gee.

"It's going to be okay, isn't it?"

"Yes." Gee-Gee had no doubt. "Every piece of it has been checked and double-checked. Even the inner workings of the critical parts have been run and rerun. This is one rocket the Earthman never had a chance to sabotage."

Rick nodded. He felt that way, too. The entire rocket had been checked out by teams of never less than two. Each man checked the other's work and both had to agree that all was in perfect order before the piece was accepted and checked off. Each man had to account to a guard before he could go to work. The system was foolproof. Now only the ultimate steps remained, the final checks, the fueling, and at the very last, the placement of the tiny spacemonk in his specially designed carrier.

"Let's go," Gee-Gee said.

They mounted the elevator and were whisked upward to the final stage. Gee-Gee picked up his walkie-talkie from the rack. "Do you read me, Dick?"

"Go ahead, Gee-Gee."

"Tell Jerry to go through checkoff."

Rick and Gee-Gee stood on the ramp and looked down at the ridiculously tiny wings and watched the control surfaces move in response to Jerry's gentle touch on the controls within the blockhouse. The drone control was working perfectly. Rick felt a surge of pride. This particular part of Pegasus was his.

The two went into the confined space in the nose. It was circular, the structural members rising to a near-peak overhead. A radar unit blocked out the tip of the nose cone. Under the unit a heavy steel channel ran down to the side of the drone control. Fixed to the channel by heavy springs was a tiny chair, complete with straps. The chair was festooned with wires, unconnected for the moment. The wires terminated in instruments that would sense every action, every response of the spacemonk's body. The chair channel was pivoted, so the monk would always be upright.

At Gee-Gee's order, Jerry Lipton ran through the check procedures again. This time Rick and Gee-Gee carefully watched the functioning of each servomotor. Finally Gee-Gee announced that he was satisfied. Next step was to check the spacemonk's instruments' circuits.

Rick picked up a tiny stethoscope. It would be taped to the monk's body, held tightly to his heart. He traced the circuit to where it disappeared into the oscillator switch, then took the walkie-talkie. "Display on? Checking the stethoscope."

"Go ahead," Earle replied.

Rick held it to his own heart for a few minutes, then tapped on the bell with his forefinger.

"Looks good on the display," Dick's voice came back. "What did you hit it with – a hammer?"

"Finger," Rick said. "Let's take a temperature next." He found the thermocouple that would be attached to the marmoset's body, traced the circuit to the oscillator, then called, "Watch my own body heat." He tucked the sensing element under his armpit.

"Hotter than a pistol," Dick said.

"Why? Do I have a fever?"

"Not unless you're a monkey. Next?"

"Sphygmomanometer. And don't worry about the pronunciation. The blood-pressure cuff." He traced the circuit, then inflated the rubber and fabric cuff.

"You just had heart failure," Dick reported.

They continued work, checking the radar equipment, the photon counters, cameras, the temperature-sensing devices, and myriad other instruments. Each instrument would feed its information to the oscillator, through the measurand transmitter and into the telemetering circuit, traveling by radio circuit back to the blockhouse. In the blockhouse it would appear in several forms. The information from the marmoset's instruments would appear as a series of waves on continually moving strips of special paper, in a machine called the display.

Finally Rick and Gee-Gee left the nose section and started to work down. It was already dark outside. The nose section was finished. The cameraman had arrived and loaded the cameras and departed. Now it remained only to place Prince Machiavelli, which was among the very last things to be done. Rick had hoped to carry the little monk to his seat, but Frank Miller and Dr. Bond had been given that job. He and Gee-Gee would be too busy with last-minute checks.

Gee-Gee was hard to satisfy. He told a guard, "Watch the nose section. No one is authorized to enter now until the monk is placed at zero minus thirty minutes." Then he led Rick across the desert to the blockhouse.

There were sandwiches and coffee on a table near the door. They helped themselves, then went and stood behind Dick Earle, who was paired off with Charlie Kassick.

"Punch up the nose section," Gee-Gee requested.

Dick ticked off the circuits as he pressed the buttons. One by one the red lights switched to green. All were operating. Only then did Gee-Gee nod his satisfaction. "Okay, Rick. Let's get back to work. Most of it's done, but we still have some checking to do in the first and second stages."

As they mounted the crane again Rick looked up at the festooned cables that terminated in the nose cone. At the moment of firing, the cables would drop off. After that, Pegasus would be on its own.

It was after dawn when the two emerged from the final check. The fueling crews were already at work. The loud-speaker on the crane emitted, "The time is zero minus twenty-five."

Gee-Gee departed for the blockhouse. Rick started after him, then as he cleared the gate he saw Scotty. His pal was waiting patiently in the jeep.

"Just wanted you to know I'm standing by," Scotty said. "You'll be in the blockhouse, I suppose?"

"That's right. Where will you be?"

"Watching the warehouse. Luis is watching it now. I suppose some of the security boys are, too, but I haven't seen them." Scotty's eyes traveled up the great rocket. "It's a honey. Suppose the Earthman has got in his licks?"

Rick shook his head. "Positively not. It's been checked out from nose to fins, and guarded every minute."

Scotty started the jeep motor. "I'd better get out of here. Good luck." The jeep roared off.

Rick turned for a last look at close range, and his eyes traveled up and up, from the stabilizing fins past the wings to the nose cone. Pegasus was ready. Then, he suddenly realized, the nose hatchway was still ajar.

That was strange. Prince Machiavelli should be installed in his seat by now and the hatchway buttoned for take-off. Rick ran to the gate, exchanged his badge for the special badge, and hurried to the crane. He half expected Dr. Bond and Frank to appear in the hatchway, but neither did.

"I'd better see," he muttered.

"The time is zero minus fifteen," the speaker stated.

Rick went up the elevator, hurried up the last few steps, and swung the hatch open. He took the flashlight from his belt kit and swung it around the interior. Prince Machiavelli blinked at him from a cocoon of tapes and straps. The light hurt the monk's eyes. Rick clicked it off and moved to the little marmoset's side. He stroked the tiny head. Why wasn't the hatch locked? Someone must have forgotten something. He walked over and peered through one of the two thick glass ports, expecting to see someone coming up the crane, but there was no sign of Dr. Bond or Frank.

Then, as he turned, the hatchway swung shut. For an instant Rick thought it had closed of its own weight, then he heard the scrape of metal as it was dogged down. Suddenly frightened he crossed the little room and banged on it, but the thick metal gave no sound under his fists. He had to make more noise! He lifted the flashlight to bang it on the door, and in that moment there was a scream of metal from outside as the crane was pulled away. He was locked in! Locked in the rocket! And it was ready to fire!

CHAPTER XVI
The Board Shows Green

Even through the rocket's walls the sound of motors and the creak of metal could be heard, and Rick knew that any slight noise he could make would never be noticed.

Frantic, he ran to the thick port and looked out. Surely there must be some way he could attract attention! The flashlight in his hand reminded him. He aimed it through the port and flashed a rapid SOS, SOS, SOS. Someone would see it! Someone must!

Frantically he flashed his SOS through the port, then ran to the other port and began flashing there. Why didn't someone respond? Everyone carried a flashlight. Why didn't someone think of signaling him that he had been seen?

He knew the answer. He hadn't been seen.

The flashlight picked out his wrist watch. It was now zero minus five! He stood at the port and kept flashing, his mind racing. Apparently whoever had closed the door hadn't known he was inside. His light hadn't been on at that moment. But it didn't make any difference now, because he was locked in from the outside. There was no way of opening the hatchway from inside.

Four minutes.

He had to think of something! Everyone was so occupied with last-minute details that probably no one was even looking at the rocket. Besides, it was light outdoors. His flashlight would be only a dim glow in the rising sunlight.

There had to be another way. He forced himself to calmness. Approach it logically, he told himself sternly. The way to do it is to signal the blockhouse.

He studied Prince Machiavelli, looking for a clue in the spacemonk's draping of instruments. He could tap on the bell of the stethoscope. But then he realized the display would not yet be rolling.

He had a quick vision of Dick Earle and Gee-Gee watching the master board, checking the circuit lights as they flicked from red to green. The board must be nearly all green now, he thought – and in the same instant he knew how he could attract attention.

Rick jumped to the center of the tiny room and crouched over the drone control. He removed the cover. There was one circuit that served only as a feed to the board, to show that the control was operative. Break that and the board would show red.

His flashlight probed the maze of wiring and he located the signal wire. Fishing into the spaghetti with his fingers, he got thumb and forefinger on it and tried to break it. The wire held.

He fumbled in his belt kit and found a pair of side-cutting pliers. They would do. He reached in and snipped the circuit wire, then he slumped down on the deck and mopped rivulets of water from his face.

Close! He glanced at his watch.

Zero minus two.

He grinned foolishly. This would be something to tell his grandchildren. Once, because of a silly mistake he came within two minutes of being the first spaceman!

Prince Machiavelli was looking down at him, the furry little face serious, like that of a very wise old owl. In the irregular light through the ports the tufted ears made the spacemonk look even more owl-like.

"At least I got you a little reprieve by saving my own skin," Rick said aloud. "Poor little guy."

The marmoset chirruped happily, glad of the human companionship.

Zero minus one minute.

Rick wasn't worried about the passage of time. Not until the drone circuit was thrown into operation in another thirty seconds would Gee-Gee and Dick realize that it wasn't functioning. A yell would stop Dr. Bernais, and the gantry would be wheeled back into place. Gee-Gee and Dick would probably come personally to check the circuit and find out why the board had shown red instead of switching to green.

Rick chuckled. What a surprise they'd get!

Fortunately, it would only take a few minutes to repair the signal wire and clear out. Pegasus would be a little late – perhaps fifteen minutes.

Again his thoughts turned to the awful moment when the hatchway closed. Now that he could think more calmly, he decided that whoever had closed the hatch hadn't known he was inside. The interior was gloomy, and he had switched his light off to keep it from shining in the marmoset's eyes.

He still couldn't be sure why the hatchway had been open, but in all probability Frank or Dr. Bond had simply gone down the gantry without closing it, not realizing until they were down that the team responsible for installing the spacemonk was also responsible for buttoning up.

There was no evidence of sabotage that he could see, so the open hatchway was nothing but the kind of mistake people make when working under extreme pressure.

Again he wondered about the identity of the Earthman. It was curious that no evidence of sabotage had been found in Orion, even though the theft of servomotors had taken place. Maybe, as Dr. Hiller had guessed, the picture left by the Earthman had been burned. Anyway, Pegasus was proof the Earthman wasn't infallible. This was one project he hadn't been able to sabotage.

His eye caught the glimmer of white on the bulkhead behind the spacemonk. He didn't remember that. He got up and walked over to it, peering to see in the dimness. Then he remembered his flashlight and focused the beam on the paper.

The blood drained from his head and he gasped. It was a sketch of a knight in armor, lance upraised, thrust through a winged rocket!

Rick let out a hoarse yell.

In the same instant he heard a whine, a rapidly accelerating whine. The pumps! The fuel pumps! The starting sequence had begun!

He looked at his watch, and saw that zero time was many seconds past. But surely his watch was wrong. The board was red! Wasn't anyone watching? He ran to the port and looked out at the deserted desert. He was alone in the great rocket, and the fuel pumps were going. He could almost picture the stream of boron hydride blending with the oxidizer and flowing in an ever-increasing stream toward the combustion chamber. He heard the scrape as the instrument cable dropped away outside.

Pegasus roared!

And Rick knew. He knew that somehow he had failed, that the board showed green!

CHAPTER XVII
Weight, One Ton

Rick had no time to think. He reacted. He pulled off the jacket he had worn against the chill of the desert night, and rolled it tightly. He dropped to the deck and stretched flat on his back, the jacket tucked under the back of his head and neck.

He put his hands flat on the deck and sensed the increasing shudder of the great rocket. It was building thrust! Fuel poured into the combustion chamber and fantastically hot exhaust gases flared from the motor exhaust. And with each passing second thrust built up inside the motor chamber.

When the thrust exceeded the rocket's weight, Pegasus would take off!

He knew it wouldn't be long. Seconds more.

The entire rocket screamed as vibration ran in torturing waves through its metal skeleton and skin. It passed the point of discomfort and became unbearable. Rick rocked his head from side to side, as though to get rid of the shattering howl, but it tore at his head, at his stomach, at his very skin.

He closed his eyes for a moment, and when he opened them again he saw that Prince Machiavelli had moved, downward. The powerful springs that held his little chair were lengthening.

Air-borne!

Rick became conscious of weight. He was being pressed into the metal deck by a mighty hand. It was hard to breathe.

Pegasus was not designed to accommodate humans. No attention had been paid to limits of human endurance. It was all right for the marmoset; his spring chair would take up much of the G forces. But Rick had no padding at all, except for the thin jacket under his head. He had no support but the metal deck, and before this was over his body would be terribly distorted as forces many times gravity rammed him relentlessly into the metal.

In spite of the horrifying scream of the rocket and the increasing pressure, his mind was clear. The rocket was programmed to reach twelve G during first-stage flight – twelve times the force of gravity!

First-stage flight would last slightly over three minutes. By then, Pegasus would be nearly thirty miles up.

The pain began, the pain of tortured muscles and organs pressed slowly, inexorably toward the deck as acceleration built up. Rick wanted to turn over, at least to change the direction of pain, but he couldn't even do that. He was spread-eagled on the deck now, his muscles unable to move his increased weight.

Consciousness began to slip from him, and he fought against it. He had to remain alive! He was going to!

For a brief moment he succeeded, then the grayness moved in like an all-encompassing curtain.

Pegasus climbed into the blue sky, arrow-straight, still accelerating. The seconds ticked away. For an instant, the accelerometer hovered at twelve G, and slipped toward thirteen.

Rick was five feet, ten inches tall, and his weight was a constant hundred and sixty pounds. The rocket reached maximum acceleration, 12.6g, and for that instant Rick weighed 2,016 pounds – slightly over one ton!

Then.. all burnt, fuel exhausted, the first-stage motor stopped.

The explosive bolts went into action. There was an explosion that made itself felt in the skin of the rocket, and the grinding of metal as the first stage detached.

Rick's battered brains swam back to consciousness. For an instant he couldn't recall what had happened, then he realized he had survived the first-stage acceleration. He was in bad shape, he knew. The salt taste in his mouth was blood, and he was breathing bubbles of blood through internal damage in his nose or lungs. But there wasn't time for inventory. The aching silence was lost as the second stage fired. Acceleration built again. This time Rick slipped into the enveloping grayness almost at once. The acceleration was less, and the time of burning was less. Had he not been put through the torture of first-stage acceleration he could have taken the second stage without more than great discomfort. But now he had little resistance left.

He came back to consciousness again as the second stage cut off. In the welcome silence he found time to be thankful he was still alive, even though it might be a temporary thing. He looked up at Prince Machiavelli through bloodshot eyes and couldn't see the little monk. For a terrible instant he thought he was blind, then he saw a glimmer of light through the port. It was the sun. The rocket was in the wrong position to catch it directly, however, and the atmosphere was far too thin to scatter light.

He heard the second stage explode off and tried to brace himself for the final acceleration. He made himself think. He was in a spot, a very bad spot. The Earthman had sabotaged the flight. But how? The first two stages had worked. Even if the third-stage motor never fired, the rocket was high enough to prove out the project objective.

There was only one answer. Even to his fogged brain it was clear that the drone control had been sabotaged by the Earthman. Otherwise cutting the signal wire would have kept the board from showing green. Somehow, the signal wire had been bypassed, to keep the operators from knowing the drone control was inoperative.

The final stage fired and acceleration began once more. Rick fought it. He tried to ignore the pain of the crushing, distorting weight and tried to keep his mind on the problem. He failed.

Pegasus was no longer traveling straight out from earth now. The gimbaled rocket motor swung slightly to one side and the rocket's trajectory flattened. As it swung on the new course, sunlight glanced in through the open port and into Rick's open, sightless eyes.

It was raw sunlight, unfiltered by the atmosphere. It was sunlight no human had ever seen before. Even in his semiconscious state Rick realized the danger and managed to shut his eyes. The sunlight seemed to burn through the lids, to scorch the insides of his head. Then the rocket moved along its new trajectory slightly and the merciless beam shifted, blazed on the sketch of a knight in armor impaling Pegasus with his lance.

Rick realized dimly that the terrible light was gone. He opened his eyes and saw the spacemonk. It was as though someone had drawn layer after layer of gauze between the boy and the marmoset, but he understood that Prince Machiavelli was still alive, and in far better shape than he was.

The vibrating, paralyzing scream of the rocket suddenly cut off. Silence flooded in.

End of burning for stage three!

Pegasus had altered course slightly, in response to its pre-set mechanisms. Now it was on a course that would take it to the maximum point into space, but at the same time would keep it over Scarlet Lake. For a few minutes more it would coast on its momentum, slowing constantly until it reached maximum altitude. Then, briefly, it would hesitate.

Momentum used up, earth's gravity would again assume control. The rocket would slip back, tail first, slowly, slowly, then faster and faster, beginning the long, final plunge to the ground.
