“Got a bogey at three o’clock high. Range about six hundred miles.” Johnson spoke casually, but his voice in the intercom was thin with tension.

Captain Paul Coulter, commanding Space Fighter 308, 58th Squadron, 33rd Fighter Wing, glanced up out of his canopy in the direction indicated, and smiled to himself at the instinctive reaction. Nothing there but the familiar starry backdrop, the moon far down to the left. If the light wasn’t right, a ship might be invisible at half a mile. He squeezed the throttle mike button. “Any IFF?”

“No IFF.”

“O.K., let me know as soon as you have his course.” Coulter squashed out his cigar and began his cockpit check, grinning without humor as he noticed that his breathing had deepened and his palms were moist on the controls. He looked down to make sure his radio was snug in its pocket on his leg; checked the thigh harness of his emergency rocket, wrapped in its thick belly pad; checked the paired tanks of oxygen behind him, hanging level from his shoulders into their niche in the “cradle.” He flipped his helmet closed, locked it, and opened it again. He tossed a sardonic salute at the photograph of a young lady who graced the side of the cockpit. “Wish us luck, sugar.” He pressed the mike button again.

“You got anything yet, Johnny?”

“He’s going our way, Paul. Have it exact in a minute.”

Coulter scanned the full arch of sky visible through the curving panels of the dome, thinking the turgid thoughts that always came when action was near. His chest was full of the familiar weakness--not fear exactly, but a tight, helpless feeling that grew and grew with the waiting.

His eyes and hands were busy in the familiar procedure, readying the ship for combat, checking and re-checking the details that could mean life and death, but his mind watched disembodied, yearning back to earth.

Sylvia always came back first. Inviting smile and outstretched hands. Nyloned knees, pink sweater, and that clinging, clinging white silk skirt. A whirling montage of laughing, challenging eyes and tossing sky-black hair and soft arms tightening around his neck.

Then Jean, cool and self-possessed and slightly disapproving, with warmth and humor peeping through from underneath when she smiled. A lazy, crinkly kind of smile, like Christmas lights going on one by one. He wished he’d acted more grown up that night they watched the rain dance at the pueblo. For the hundredth time, he went over what he remembered of their last date, seeing the gleam of her shoulder, and the angry disappointment in her eyes; hearing again his awkward apologies. She was a nice kid. Silently his mouth formed the words. “You’re a nice kid.”

I think she loves me. She was just mad because I got drunk.

The tension of approaching combat suddenly blended with the memory, welling up into a rush of tenderness and affection. He whispered her name, and suddenly he knew that if he got back he was going to ask her to marry him.

He thought of his father, rocking on the porch of the Pennsylvania farm, pipe in his mouth, the weathered old face serene, as he puffed and listened to the radio beside him. He wished he’d written him last night, instead of joining the usual beer and bull session in the wardroom. He wished--. He wished.

“I’ve got him, Paul. He’s got two point seven miles of RV on us. Take thirty degrees high on two point one o’clock for course to IP.”

Automatically he turned the control wheel to the right and eased it back. The gyros recorded the turn to course.

“Hold 4 G’s for one six five seconds, then coast two minutes for initial point five hundred miles on his tail.”

“Right, Johnny. One sixty-five, then two minutes.” He set the timer, advanced the throttle to 4 G’s, and stepped back an inch as the acceleration took him snugly into the cradle. The Return-To-Station-Fuel and Relative-Velocity-To-Station gauges did their usual double takes on a change of course, as the ship computer recorded the new information. He liked those two gauges--the two old ladies.

Mrs. RSF kept track of how much more fuel they had than they needed to get home. When they were moving away from station, she dropped in alarmed little jumps, but when they were headed home, she inched along in serene contentment, or if they were coasting, sneaked triumphantly back up the dial.

Mrs. RVS started to get jittery at about ten mps away from home, and above fifteen, she was trembling steadily. He didn’t blame the old ladies for worrying. With one hour of fuel at 5 G’s, you didn’t fire a single squirt unless there was a good reason for it. Most of their time on a mission was spent free wheeling, in the anxiety-laden boredom that fighting men have always known.

Wish the Red was coming in across our course. It would have taken less fuel, and the chase wouldn’t have taken them so far out. But then they’d probably have been spotted, and lost the precious element of surprise.

He blessed the advantage of better radar. In this crazy “war,” so like the dogfights of the first world war, the better than two hundred mile edge of American radar was more often than not the margin of victory. The American crews were a little sharper, a little better trained, but with their stripped down ships, and midget crewmen, with no personal safety equipment, the Reds could accelerate longer and faster, and go farther out. You had to get the jump on them, or it was just too bad.

The second hand hit forty-five in its third cycle, and he stood loose in the cradle as the power died.

Sixty-two combat missions but the government says there’s no war. His mind wandered back over eight years in the service. Intelligence tests. Physical tests. Psychological tests. Six months of emotional adjustment in the screep. Primary training. Basic and advanced training. The pride and excitement of being chosen for space fighters. By the time he graduated, the United States and Russia each had several satellite stations operating, but in 1979, the United States had won the race for a permanent station on the Moon. What a grind it had been, bringing in the supplies.

A year later the Moon station had “blown up.” No warning. No survivors. Just a brand-new medium-sized crater. And six months later, the new station, almost completed, went up again. The diplomats had buzzed like hornets, with accusations and threats, but nothing could be proven--there were bombs stored at the station. The implication was clear enough. There wasn’t going to be any Moon station until one government ruled Earth. Or until the United States and Russia figured out a way to get along with each other. And so far, getting along with Russia was like trying to get along with an octopus.

Of course there were rumors that the psych warfare boys had some gimmick cooked up, to turn the U. S. S. R. upside down in a revolution, the next time power changed hands, but he’d been hearing that one for years. Still, with four new dictators over there in the last eleven years, there was always a chance.

Anyway, he was just a space jockey, doing his job in this screwball fight out here in the empty reaches. Back on Earth, there was no war. The statesmen talked, held conferences, played international chess as ever. Neither side bothered the other’s satellites, though naturally they were on permanent alert. There just wasn’t going to be any Moon station for a while. Nobody knew what there might be on the Moon, but if one side couldn’t have it, then the other side wasn’t going to have it either.

And meanwhile, the struggle was growing deadlier, month by month, each side groping for the stranglehold, looking for the edge that would give domination of space, or make all-out war a good risk. They hadn’t found it yet, but it was getting bloodier out here all the time. For a while, it had been a supreme achievement just to get a ship out and back, but gradually, as the ships improved, there was a little margin left over for weapons. Back a year ago, the average patrol was nothing but a sightseeing tour. Not that there was much to see, when you’d been out a few times. Now, there were Reds around practically every mission.

Thirteen missions to go, after today. He wondered if he’d quit at seventy-five. Deep inside him, the old pride and excitement were still strong. He still got a kick out of the way the girls looked at the silver rocket on his chest. But he didn’t feel as lucky as he used to. Twenty-nine years old, and he was starting to feel like an old man. He pictured himself lecturing to a group of eager kids.

Had a couple of close calls, those last two missions. That Red had looked easy, the way he was wandering around. He hadn’t spotted them until they were well into their run, but when he got started he’d made them look like slow motion, just the same. If he hadn’t tried that harebrained sudden deceleration ... Coulter shook his head at the memory. And on the last mission they’d been lucky to get a draw. Those boys were good shots.

“We’re crossing his track, Paul. Turn to nine point five o’clock and hold 4 G’s for thirty-two seconds, starting on the count ... five--four--three--two--one--go!” He completed the operation in silence, remarking to himself how lucky he was to have Johnson. The boy loved a chase. He navigated like a hungry hawk, though you had to admit his techniques were a bit irregular.

Coulter chuckled at the ad lib way they operated, remembering the courses, the tests, the procedures practiced until they could do them backwards blindfolded. When they tangled with a Red, the Solter co-ordinates went out the hatch. They navigated by the enemy. There were times during a fight when he had no more idea of his position than what the old ladies told him, and what he could see of the Sun, the Earth, and the Moon.

And using “right side up” as a basis for navigation. He chuckled again. Still, the service had had to concede on “right side up,” in designing the ships, so there was something to be said for it. They hadn’t been able to simulate gravity without fouling up the ships so they had to call the pilot’s head “up.” There was something comforting about it. He’d driven a couple of the experimental jobs, one with the cockpit set on gimbals, and one where the whole ship rotated, and he hadn’t cared for them at all. Felt disoriented, with something nagging at his mind all the time, as though the ships had been sabotaged. A couple of pilots had gone nuts in the “spindizzy,” and remembering his own feelings as he watched the sky go by, it was easy to understand.

Anyway, “right side up” tied in perfectly with the old “clock” system Garrity had dug out of those magazines he was always reading. Once they got used to it, it had turned out really handy. Old Doc Hoffman, his astrogation prof, would have turned purple if he’d ever dreamed they’d use such a conglomeration. But it worked. And when you were in a hurry, it worked in a hurry, and that was good enough for Coulter. He’d submitted a report on it to Colonel Silton.

“You’ve got him, Paul. We’re dead on his tail, five hundred miles back, and matching velocity. Turn forty-two degrees right, and you’re lined up right on him.” Johnson was pleased with the job he’d done.

Coulter watched the pip move into his sightscreen. It settled less than a degree off dead center. He made the final corrections in course, set the air pressure control to eight pounds, and locked his helmet.

“Nice job, Johnny. Let’s button up. You with us, Guns?”

Garrity sounded lazy as a well-fed tiger. “Ah’m with yew, cap’n.”

Coulter advanced the throttle to 5 G’s. And with the hiss of power, SF 308 began the deadly, intricate, precarious maneuver called a combat pass--a maneuver inherited from the aerial dogfight--though it often turned into something more like the broadside duels of the old sailing ships--as the best and least suicidal method of killing a spaceship. To start on the enemy’s tail, just out of his radar range. To come up his track at 2 mps relative velocity, firing six .30 caliber machine guns from fifty miles out. In the last three or four seconds, to break out just enough to clear him, praying that he won’t break in the same direction. And to keep on going.

Four minutes and thirty-four seconds to the break. Sixty seconds at 5 G’s; one hundred ninety-two seconds of free wheeling; and then, if they were lucky, the twenty-two frantic seconds they were out here for--throwing a few pounds of steel slugs out before them in one unbroken burst, groping out fifty miles into the darkness with steel and radar fingers to kill a duplicate of themselves.

This is the worst. These three minutes are the worst. One hundred ninety-two eternal seconds of waiting, of deathly silence and deathly calm, feeling and hearing nothing but the slow pounding of their own heartbeats. Each time he got back, it faded away, and all he remembered was the excitement. But each time he went through it, it was worse. Just standing and waiting in the silence, praying they weren’t spotted--staring at the unmoving firmament and knowing he was a projectile hurtling two miles each second straight at a clump of metal and flesh that was the enemy. Knowing the odds were twenty to one against their scoring a kill ... unless they ran into him.
