And what if you decide NOT to! Are you a criminal to be hunted down? Bill Morrow fished his cigarettes out, shook one loose, and poked it between his lips. He lighted it with hands that shook badly, he leaned back on the workbench and blew smoke in a long, heavy sigh. His gaze remained fixed on the compact little chunk of glittering grids, coils, and metal loops that floated in the center of the room. Floated, by Isaac Newton—floated! It worked. It worked beautifully! He'd merely inserted the four dry-cell flashlight batteries into their clamps and thumbed the switch on the little face-panel. The tiny pilot-light winked on, the needle jiggled on the single instrument dial— And it worked. It had risen gently from the workbench, floating into the air.... Then, seemingly, it had fostered a dislike for the workbench. It slid off and bounced toward the floor—bounced, up and down in the air, gently—and floated on across the cellar toward the oil furnace in the corner. But as it approached the oil furnace, it had decided it didn't like that either—so it deflected its course and floated toward the concrete cellar wall. But it didn't like the wall. So it reversed its course and retreated to the center of the room. There it hovered, four feet above the cement floor, four feet below the rafters of the cellar roof. It hovered in mid-air. Morrow stared at it, critically. He could capture it—get it between himself and the wall, and reach out and grab it before it could slip away—and touching it wouldn't harm him. The magneto-gravitic coils didn't need high voltage. It was working on its lowest "volume" setting. The only word applicable was "volume" because he used an ordinary volume-control grid and knob to adjust its power—and, again, "power" was the only applicable word. He might have to invent a few new words for it. But on its lowest volume setting, it was supporting its own weight—suspending itself in the Earth's gravitic field. And since gravitic forces were also magnetic forces, he would weigh a fraction of a pound lighter when he grabbed hold of the mechanism—just he, himself, since he wore rubber-soled shoes. If he turned up its volume, it would exert greater influence on the molecular structure of itself and of his body—and perhaps of a few grains of dust on the cement floor beneath his feet—by simple mass-attraction and conductivity. Of course, "mass-attraction" and "conductivity" were also obsolete terms—except that they described two different results of the same natural phenomenon. The floating mechanism affected the basic phenomenon itself— And was the closest Einstein could come to explaining that! Still, a word could be invented for it, Morrow supposed. Not that he understood what the new word was supposed to define—but then, had Edison known what electricity was? No! He had merely experimented and learned what it would do, and then designed mechanisms which would utilize it. Morrow didn't know what "gravity and magnetic moment" was, either—nor "angular momentum"—but he had discovered what it would do. It, not they—it was all the same thing. And he designed a mechanism. And the mechanism worked. It defied "gravity." With its volume turned up, it could very probably lift him to any height above the Earth he desired, with its ability growing weaker only as it rose out of the Earth's gravity and magnetic field. And it would keep him suspended, if he desired, until its batteries burned out. There would be limitations, of course. Perhaps the Earth's gravity and magnetic fields would be too weak at, say, an altitude of fifty miles for the mechanism to function. There were probably limits to the mass and weight it could lift. There would have to be extensive tests— And a cellar workshop was no place to conduct them! He straightened up from the workbench and moved forward on the balls of his feet. He spread his arms wide as he approached the mechanism, like a basketball player approaching a wary opponent who had the ball. Smoke from the cigarette dangling out of the corner of his mouth streamed up and stung his eye. He wished he had left it back on the workbench. At first, the little mechanism ignored him. Then, almost instinctively, it seemed to notice him. It went sliding away from him, toward the wall. Morrow moved forward, cautiously. It glided close to the wall, then rebounded gently. It came drifting back toward him—then hesitated, started off in a tangent—and he grabbed for it. A faint, tingling shock went up his arm as he clawed at the shiny metal loops, but that was all. He hung on grimly as it tugged at his fingertips; then, as its influence swept through him and attuned his body to it, it snuggled up to him, suddenly friendly. He snapped it off and felt its inert weight settle down familiarly in his hands. He carried it back to the workbench, set it down, and threw a rag over it. Then he pulled off his coveralls, went upstairs to the kitchenette, and washed his hands. There were other factors to consider, of course. Especially the ones he didn't want to think about—the frightening ones— He stared down at his hands, feeling the cool water run pleasantly over them. Strong, supple hands. Well-proportioned, muscular. A little bit like the rest of him. Not fat or skinny, not soft-muscled nor, again, as bulgingly muscular as a wrestler. Just firm flesh, strong and not too much of it, on a strong-boned skeleton frame. Nerves well-coordinated, reflexes good. But tired. Mentally fatigued, the psycho-therapists said, from living in a world of raw tensions. According to them, ninety percent of the American public suffered mental fatigue. There had been a slew of magazine articles and several books about it. The Cold War, the war that wasn't a war. The Russkies. Morrow turned off the cold-water tap and glanced at his image in the shaving mirror. A slender face, a good nose, a firm mouth with slightly too much jaw. Dark hair tumbled in comfortable looseness over a lined forehead. Gray eyes that mocked him as he mocked himself. He dried his hands and got a couple of cans of beer out of the refrigerator. Grabbing a can-opener and a glass, he strolled in through the small, dark bedroom to the front living room and sprawled himself out in the deep chair beside the television set. It was a small home, a comfortable home, and he enjoyed prowling around in it in his socks, loafers, and shorts. He scratched his left leg and opened a can of beer. He was, Morrow concluded, the product of an age of terror. East was Russia and west was the Allied Nations, and in between was a veritable No Man's Land. Radar blanketed the skies, rocket missiles stood on their firing-racks, long-range bombers waited to deliver atomic death and swift jet-fighters waited to do battle with them. The diplomats called it a balance of power; the military strategists, a balance of forces, wherein neither side could launch an atomic war without suffering complete annihilation by the other. And so, said the statesmen, there would be no atomic war. The only trouble was, they couldn't convince the people. Too many self-minded individuals saw the world situation as two sticks of dynamite rubbing against each other. At any moment, both might explode. Massive war industry and compulsory military training for their youngsters didn't make the public feel any more secure. Nor, of course, did the generals want them to feel secure. The Allied generals moved their armies in threatening maneuvers near critical borders to increase the fear of the peoples in communist-dominated countries; the Russian generals did likewise to increase the fear of people in the Allied Nations. And the diplomats hurled threats back and forth in the United Nations' assemblies to achieve the same purpose. Militarily, the two sides had reached a stalemate. The final weapon was the people. Each side hoped the people of the other side would rise up in revolt, thus breaking the deadlock and winning the struggle, but humanity is notoriously stubborn. It was, nonetheless, rather hard on the people. Individual lives were deeply affected, sometimes for better and sometimes for worse. Morrow's life had, so far, been for the better. In high school, certain aptitude tests had placed him in advance physics classes; upon graduation, at seventeen, he had spent a year in a government-sponsored engineering school. At eighteen, further tests had placed him in the Air Force, assigned as radar-operator to the rear cockpit of a sleek, all-weather jet-fighter. He spent two years patrolling the stratosphere over the vast, white expanse of the Arctic Ocean. At twenty, he was reassigned to engineering school and spent four years studying electronics, during which time he was returned to civilian status. He was placed at Western Electronics as a production engineer; by the time he was twenty-seven, he had worked his way up to the Research Division. His flying experience helped considerably, but it wasn't all. He was deeply in love with electronics. He had studied Einstein's equations, for example, and got something out of them that most of the others missed. No one knew exactly what it was—neither did Morrow—but he began to have "hunches" that often paid off. In electronics, that was a priceless faculty. A great deal of it, especially in the research department, was still pretty much of a hit-or-miss affair. There still wasn't a man who knew exactly what electricity was! Now, at twenty-nine, he had gotten another of those "hunches." It worked, too! The machine floated! He gazed thoughtfully out the broad picture window at the stretch of green lawn, the sidewalks, the trees along the street and the other little prefab houses of his neighbors. The evening shadows were cool and deepening as night approached. Warm, yellow light poured from the windows across the street. He was comfortable here in his little, company-owned bachelor's home. Most of the town of Westerton was owned by Western Electronics, with its huge, sprawling plant buildings on the other side of the small valley, across the railroad tracks. Like most of the bachelor engineers, he ate most of his meals over at the company cafeteria. A cleaning-woman came twice a week to tidy up his little house, though he was a fairly conscientious housekeeper himself. And like practically all the engineers, he had a small workshop patched together in his cellar, built from odds and ends salvaged from the company's junk-pile of rejected parts, a few pieces scrounged from the laboratories, and some odd bits made in the machine-shop over the protests of its foreman. There were nine amateur radio-hams sharing the wave-bands in Westerton and vicinity, and no office-clerk's housewife ever had any difficulty getting a recalcitrant dishwasher or electric iron fixed. It was here, in his private workshop, that he had developed his "hunch" to startling reality. Working in his spare time, figuring out its mathematical components, then working those components into theoretical diagrams, then designing and building the machine to fit the diagrams—and it worked! Also, it was fantastic. It had been a little too fantastic for him to mention it to any of the others at the labs. His fellow-engineers—some of whom were considerably older than he was—were a little too staid for that. They, too, were products of the age; their entire efforts and, indeed, most of their interests were tied up in the one, basic problem of making better electronic devices for better weapons for the Armed Forces. They couldn't be blamed for that, the world situation being what it was, but it did make them somewhat hide-bound. The idea of controlling the pull of gravity was a little too fanciful for them, Morrow feared—or if they had any interest in the idea at all, it would be in the possible uses of it as a military weapon. That was the way to get ahead as a scientist, these days! Morrow shuddered involuntarily. There was the thing he actually feared! He drew it into his thoughts, slowly, and analysed it. Item: he had discovered a means of controlling gravity. Item: he had developed a mechanism which worked on that principle. Addenda: the mechanism could lift a human being, quite possibly as much mass as a heavy tank, and it might even open the way to interplanetary travel. Quite obviously, it had terrific potentialities as a weapon of war. And it was his patriotic duty, as a citizen of the United States, to turn his discovery over to the authorities. Well, suppose he did? It would come as an even greater shock than was the development of the atomic bomb—of that, he was sure. It would become a top-secret project. Gradually, each individual unit of the entire Armed Forces would be made airborne. The Infantry would take to the skies, supported by airborne artillery and tanks; the Air Force and Navy would combine to send giant battleships gliding through the stratosphere, unhindered by any shore-line and capable of both artillery fire and aerial bombardment. How could anything as big as that be kept secret? The answer was, it couldn't. Such a program would hardly have begun when some Russian agent handed the entire secret over to his bosses in the Kremlin. Then Russia would launch the same sort of program. And world tension was already terrific. Mankind was already teetering on the brink of atomic war. What psychological effect would this new threat have on them? What insults would the diplomats think of, then? What charges and counter-charges would hurl between them? What final "incident" would spark the entire civilization into a raging holocaust? Or would the officials in Washington realize that outcome? Would they order his discovery destroyed, forgotten, and himself assigned to some well-guarded hunting lodge in the Canadian Northwest where he could be kept in comfortable isolation, with no one around to pluck the dreadful secret from his mind? The present balance of power had at least some promise of averting an atomic war. His discovery would destroy that balance of power, and do it suddenly, frighteningly. Someone might get just scared enough to start shooting. After that, there'd be no turning back. There would be atomic war. They probably wouldn't want their balance of power destroyed. At least, not that way. Well, then, why shouldn't he save them—and himself—a lot of trouble and simply destroy the thing himself? Forget about it, forget he'd ever thought of it? That wasn't so good, either. Personally, he was deeply anxious to begin the tests on the mechanism. There was so little he knew, actually, about what its limitations were, how they could be surmounted— But there was more to it than that. The mechanism did work, and it would lift considerable weight. Therefore, it would certainly have its uses. Air travel could be made perfectly safe. That fact prompted a vision into his mind of everybody flying around in little, teardrop plexiglass shells, landing on their roofs—and living in homes scattered over a peaceful countryside. Cities could be smaller, devoted exclusively to office-buildings and industrial plants, and would suffer less congestion. Also, people would become accustomed to travelling greater distances. A thousand miles might be a comfortable afternoon's ride. This, in turn, would mean greater travelling and exchange between various nations. Then, there was the fact that commercial shipping would be revolutionized. Transporting air cargoes would be cheap and dependable, even for the heaviest kinds of freight. Thus, factories could be built near their power or raw material sources. They wouldn't have to be built near large railroad centers or harbors; commercial shipping would no longer be a problem. And thus, industrial areas could spread out, become less congested, have better surroundings for employee-morale and pay less property taxes. Also, they would be able to ship their products to more distant markets. International trade would increase tremendously. The world-wide competition would shatter unfair national cartels—that would take time, and many governments would fight it, but eventually they'd have to accept it or intensive smuggling would undermine their economy. In times of economic stress, black markets were often a blessing to backward, underdeveloped areas. The whole result of it would be that the entire world would be bound together far more closely. Economic ties would be predominantly international. The increased flow of travellers between nations would gradually break down prejudices and differences of custom and misunderstanding. And that would create a far stronger basis for tomorrow's world government. As civilization stood, it needed a world government desperately. Either that, or atomic energy would destroy it. Either world government or war. So there it is! Morrow concluded. He had a mechanism for controlling the pull of gravity. Either that mechanism was destroyed and forgotten, or the world's present balance of power would be destroyed and humanity plunged into atomic war. But if the mechanism was destroyed, humanity wouldn't have it for the future development of world government and civilization. And they needed it. The present automobiles, trains, and aircraft were all very streamlined and marvelous when compared to the horse and buggy, but they were still too limited, too cumbersome and too costly. There had to be something for the average man, earning the average salary, that would haul him—and extend his interests—to the far corners of the world. The mechanism would do that. Mankind would need it to develop a sound, productive future. But if it wasn't destroyed, there would be atomic war. There wouldn't be any future! It was after midnight when he rose from his chair, pulled on a pair of slacks and a sweater, and left the house. He locked the front door and walked around to the garage. Swinging the door back, he felt his way into the darkness, touched the familiar surfaces of his little motor-bike, and rolled it out to the drive-way. Mounting, he kicked the starter, and the little one-cylinder, 15 horsepower engine exploded into a throaty chatter. He rode down the dark, tree-lined streets, the cool air whipping over his body. Swinging into Railroad Avenue, he pulled over to the curb and stopped before the lighted windows of the telegraph office. He strode in, scribbled off a telegram, and paid for it. The office girl, counting the words, stopped and frowned. She shoved it back across the counter to him. "Does that make sense?" she asked dubiously. Morrow glanced over it again and smiled. It read:
He shoved it back to her. "It makes sense, all right. And I'm expecting a quick reply, so I'll be waiting across the street in Switzer's Cafe." "It may take some time—" "That reply will come as quickly as you people can handle it," Morrow retorted. "A crop-dusting pilot is accustomed to getting telegrams in the middle of the night—and answering them, before some other outfit can grab the job being offered!" The girl shrugged her thin shoulders. "All right, then. You'll be over at Switzer's—" "Right." She scribbled a note on a memo pad. Morrow turned and strode out. A feeling of elation tingled through him as he crossed the street. Calling on D.P. Smith had been a natural reaction, once the plan had begun forming in his mind. If he'd ever wanted anyone murdered, Smitty was the one man he could trust! But there was a more immediate cause for elation. It was after midnight, and Gwyn went on shift at Switzer's Cafe at midnight. She'd been on the dawn patrol for the past week, and the only time he'd seen her was when he dropped in for a quick breakfast coffee every morning. Gwyn Davidson was the only daughter of old Pat Davidson, the plant superintendent at Western Electronics. Bill had worked under Pat as a production engineer; he'd met Gwyn two months earlier when she returned home from college. Gwyn's mother had died the year before from cancer, after a lifetime of suffering and hospital bills. Old Pat was still paying off those bills, and Gwyn had been working her own way through school. Now, she was a waitress with an M.A. degree, helping out with the expenses at home. He saw her through the front window, leaning on the counter in the deserted cafe, reading the comics in a newspaper. She was a small, curvaceous girl in a blue waitress' uniform carefully chosen to fit to her best advantage. Soft, dark hair tumbled back from a tanned, healthy face that sported only a trace of lipstick. Her wide, steady gaze flicked up as he strode in, then she smiled warmly. "Hi, Bill. What're you doing up at this ungodly hour?" Pretty, firm-fleshed, and bouncy. Even though her feet are killing her! Bill thought. "Hello, Gwyn," he said. "I came down to send a telegram. Pour me some coffee, huh?" He straddled a stool before her. "I'll give you what we serve as coffee," she answered brightly, "but you'll have to pay for it!" "Fair warning. How's tricks?" "Haven't seen her lately. What's with this telegram all of a sudden?" She grabbed cup and saucer, turned, and drew a cupful from the chrome coffee-maker. "Invitation to an old friend," Bill replied half-truthfully. "All of a sudden, I'm lonesome." She swung back and slid the coffee before him. Her eyes were teasing. "Wouldn't a wife do just as well?" "A good question," he quipped back. "Come sit down and have coffee with me, and we'll talk it over!" "What?" She grinned brightly, wide-eyed. "Don't go 'way, now!" She whirled, grabbed a cup and saucer, and filled it. "I'll be right there!" She moved briskly around the end of the counter and perched herself on the stool beside him. "Now! Tell me more!" She began ladling spoon-fulls of sugar into her coffee. It was a good comedy act, done with a natural flair for perfect timing. Morrow leaned weakly on the counter, laughing silently. Gwyn gave him a glare of feigned contempt. "Oh! Just another fast-talker, huh? I might have known!" She stirred her coffee furiously. "You engineers are all alike. If father warned me once—" "Don't overdo it, honey," he cautioned her, lightly. "You know perfectly well I've enjoyed those long goodnight kisses when I've walked you home." She sobered reflectively. "All right, Bill. But just what was this mid-morning telegram about—or don't you want to tell me?" It was a casually-spoken question, and the circumstances made it a perfectly logical one. As a research engineer, Morrow worked on a number of things which had top-secret classification, and Gwyn knew he did. And I'd better classify this, too! Morrow thought slyly. "Afraid I can't," he answered her, calmly. She nodded and sipped her coffee in silence. Finally, she asked, "Will you be glad when I'm back on a day-shift?" Morrow took his turn sipping coffee and took his time forming an answer. "I want to take you swimming out at the Lakeshore Lodge, again," he said. "I still dream about the way you rolled up your two-piece suit so it was a Bikini model—" "Uh huh," she interrupted. Her tone was hardly enthusiastic. "If we do, you'd better not try making the passes at me you did the last time!" "You expect me to resist the temptation of all that beautiful skin?" he retorted, grinning down at her. She gave a pert shake of her head. "When I give in to a man, he'll be my husband," she said firmly. "And he'll be my husband because he loves me—not because he drools over my body!" "Ummm," Morrow ummed, doubtfully. He decided it would be best to change the subject. "Read the latest Universe?" "Uh huh! What'd you think of Sturgeon's story?" She was at once bright, smiling, interested. "Wasn't it wonderful? I mean, the way he so perfectly defined an alien being's intelligence—" That was science-fiction. Gwyn read the science-fiction magazines avidly, from cover to cover. Morrow read a few, along with his other reading—the Post, Harper's, the Digest, and half a dozen technical journals—and he'd even written and sold a science-fiction story once. Nineteen editors rejected it, but the twentieth bought it after having him revise it three times. But that one mutual interest had gone a long way in winning his esteem in Gwyn's mind, slight though it was. And she was cute as a bug, the sort of female who set a man's blood a-tingle. So they talked science-fiction. Alien creatures that inhabited other planets, trips across space and out to the other stars, travels through time and into other dimensions, civilizations which spread clear across the galaxy.... It was over an hour before a young messenger boy came in with the expected telegram. Morrow tipped the boy, excused himself to Gwyn, and ripped open the envelope. The message read:
Grinning, Morrow folded the yellow sheet and stuffed it into his pocket. "Everything okay?" Gwyn asked, forcing all concern from her voice. "Everything is okay," Morrow affirmed quietly. "How much do I owe you?" "Four coffees? Forty-five cents." He laid the change on the counter, then stooped and kissed her cheek lightly. "I gotta go home and get some sleep," he murmured. She smiled, a little wistfully. "Thanks for coming." He went out into the cool darkness, then hurried down to the bar on the corner and went in to use the men's room. Then he came out, crossed the street, and climbed aboard his little motor-bike. Thoughts drifted lazily through his mind as he chugged contentedly homeward.... Thoughts—and memories. They were cruising along peacefully at 40,000 feet. Morrow felt as if he were molded into the snug rear cockpit, an integral part of the tons of sleek, deadly metal that was the old F-94 jet-fighter. But he'd experienced that feeling so often it no longer mattered, then. Before him was the familiar maze of instrument dials and signal lights and switches crammed around a glowing, green-blotched radar scope. Around him was the clear, transparent canopy, with the round crash-helmet of Smitty's head poking up from the front cockpit ahead of him. Below, off the edge of the razor-thin wing, was the criss-crossed gray surface of the Arctic ice-pack. The sky was an intense blue-black sprinkled with the hard, bright sparks of stars. There were faint, rhythmic sounds around him. Familiar sounds. The warm, dry air blowing through his flight suit, circulating over his body. The air pushing into his face-mask. The rolling motion of the seat-cushions, massaging his backside with mechanical dispassion. Then the flat, metallic voice in his earphones. "Forty-three degrees left. Contact in five minutes!" "Roger!" Smitty's voice answered. The ship tilted gently. Centrifugal force pressed Morrow against his seat. The world turned slowly beneath them. Forty-three degrees. Two minutes later, a bright spark appeared on his radar scope. "Air spotted!" he spoke into his mike. "Two degrees right!" "Over to you!" the metallic voice from ground radar answered. And the jet shifted slightly. Two degrees. "Contact in two minutes," Morrow chanted. "One-thirty ... One ... Thirty—" "Contact!" Smitty's voice cracked. The F-94 whipped over into a turn. The force of two gravities shoved Morrow down in his seat. For a brief moment—a breathless, eternal moment, all of two seconds—another F-94 exactly like theirs appeared directly before them. Long enough for red lights to glow and camera guns to record a direct hit. The practice mission was completed—almost. Then Smitty snap-rolled the ship, missing the other ship almost by inches. The g's piled up, cramming Morrow down in his seat, pulling at his facial muscles. Then his vision cleared and he straightened up, bruised and somewhat battered. It was the old bomber-interceptor game. That other F-94 could have been an enemy bomber, plowing toward American cities with a load of atomic death— Smitty turned his head and looked back. His eyes crinkled into a smile under the green glaze of his goggles. Smitty. Captain Daniel Purcell Smith, then—or "D.P." Smith, which were also the initials for "Displaced Person." A cool, thoughtful, and smart jet-fighter pilot in those days, and a darned good guy. They had taken Seattle apart at the seams on their one furlough, preferring the devilment of their own companionship to going home to Mom's apple pie. Morrow's telegram had made sense, all right. The words scramble and May Day were fighter-lingo; scramble meant let's go! we've a fight on our hands, and May Day meant I'm in trouble! He was in trouble, certainly. The mechanism he'd developed was, in itself, plenty of trouble. And it was a special kind of trouble—the kind in which the only person he could dare trust had to be someone like Smitty. The Air Force camaraderie which existed between them had never quite faded out. Even after they'd been mustered back into civilian status, after Morrow had signed a government engineering contract and Smitty had gone on to commercial flying, they had kept in touch with each other. Diverging interests hadn't pulled them apart; the old school ties, the old trustworthiness was still there. An odd letter every few months or so, a postcard at Christmas.... He was fortunate to know a man like Smitty, Morrow knew. He couldn't have carried out his plan alone. He reached home, stored his motor-bike in the garage, and walked into the living room. He snapped on the light and stood there for a moment, gazing across the room at his littered writing desk. If he were going to carry out his plan, there was one thing he'd have to do himself. People weren't going to like it. Good engineers were scarce. He walked across the room, sat down at the desk, and crammed a sheet of Western Electronics stationery into his portable typewriter. He paused, lighted a cigarette, and then grimly proceeded to write his letter of resignation. "It's a mechanism that floats in the Earth's field of gravity," Morrow began— They were seated in a secluded booth in the modernistic restaurant at the Newark Airport. Through the wall-length observation window, they could look down on the airfield; a giant stratoliner was rolling up before the building, the bright spot-lights glistening off the silvery arcs of its six big turbo-props. White-uniformed linemen were pushing the steps up to the side of its fat hull as the door slid open and a pert stewardess poked her head out. Beyond the gleaming sky-monster, in the pitch darkness of early morning, the runway lights twinkled in rows and patterns of red, yellow, blue and green sparks. Morrow spoke quietly and succinctly, pausing only for a sip of coffee or a pull on his cigarette, and gave a concise briefing of his discovery and its implications. The dishes of an early breakfast had been cleared away, so no waitress bothered them and the few other patrons in the restaurant were out of ear-shot. Across from him, ex-Captain D.P. Smith sprawled laconically on the cushioned seat, listening. The expression on his lean, brown face was thoughtful, intent. He sipped his coffee and flicked the ashes of his cigarette into the saucer. He was a small, slender man dressed in a conservative, pin-stripe business suit. There was nothing dare-devil about his attitude, nor were his movements deft or quick. He was slow, cautious; his attitude was a reserved calmness. It was immediately noticeable. His carefully groomed black hair and his small, black mustache gave his features a mischievous look. There was something satanic about his small stature, his long hands, and his lean, handsome appearance. One would expect a bright, hand-painted tie and a roving, speculative eye. His utter calmness and reserve seemed incongruous. Only the faint, white scar along his jawline might have indicated a devil-may-care experience. Morrow had mentioned it, remembering that Smitty had written about the crash last year—he was making a pass over a field, spreading bug-killer spray over a farmer's potato crop, when a sudden down-draft caught his plane and he couldn't pull up in time to avoid the neighboring orchard. He'd crashed through the apple trees, snapping them like kindling. The plane was completely demolished. When I woke up, he'd written, they had me spread out on a silver tray with an apple in my mouth! Crop-dusting was a hard, dangerous job. The pilots did most of their flying before dawn or in early afternoon, when the air was calm; but they had to fly at other times, too, to make enough to meet expenses. They'd take off in small, worn-out planes, loaded beyond safety flight limits with bug-killer, and fly to some farmer's fields. Then they'd make passes back and forth over the fields, flying below-treetop, leap-frogging barbed-wire fences, zooming under telephone lines, and dodging trees and farm buildings, their eyes stinging as the spray billowed back into the cockpit. The pay they received was small, mostly because there were so many skilled pilots looking for work and so few civilian flying jobs. Smitty could easily reenlist in the Air Force, of course, but they wouldn't give him a flying job; at thirty-two, he was too old for military flying. They took the eighteen-year-olds for that. And Smitty wouldn't reenlist to sit behind a desk. So he dusted crops. It was no job for a dare-devil, either. A pilot had to know his limitations, the limitations of his plane, and what he was doing every second. "—And that's the situation," Morrow concluded. "If the mechanism isn't destroyed, it'll plunge the world into atomic war. If it is destroyed, it'll be lost to mankind for the next several hundred years—until somebody else stumbles across it." "In short," Smitty resumed, "if we got it now, we have atomic war. If we don't have it for the next few centuries, we will have atomic war." "I'm afraid so," Morrow affirmed. "Unless they manage to develop a world civilization and government without it." Smitty shook his head. "They need something like this gravity machine to pull people closer together, to get them to know more about one another. Otherwise, any world government scheme is likely to be a fizz—unless it's established by force!" "That'd amount to world dictatorship." Smitty shrugged. "All right, so we've got this thing. If we keep it, we get atomic war. If we don't, maybe our grand-children get atomic war. That it?" Morrow nodded. "So you must have some plan up your sleeve!" Smitty grinned at him, shrewdly. "You wouldn't drag me all the way up here just to listen to a hard-luck story." Morrow's eyes narrowed. "Smitty, the only reason this would cause an atomic war now is because the world situation is so tense—" "True!" "—But the world situation isn't always going to be this way! Sooner or later, something will happen to change it. Something's bound to change it! This is a modern, fast-moving world—things happen fast!" "So?" Smitty raised his brows, querulously. "Well, it's bound to change within our lifetime! And when it does, we may have an opportunity to reveal this discovery. All we have to do is wait, keep it secret, test it and develop it, and turn it loose when the time is ripe!" "Un-huh," Smitty grunted. "And who's going to pay for it?" "I've got seven thousand in the bank—" "And I've got three!" Smitty frowned scornfully. "How far do you think we'd get on ten thousand bucks, chum?" "As far as we'll need to get," Morrow retorted. "We aren't trying to finance a mass-production scheme, remember. This is strictly experimental work." "What would the retail cost amount to on that mechanism you built?" he asked dubiously. Morrow scratched his jaw, reflectively. "Retail cost it'd run to around three hundred dollars." "So we make a bunch of those mechanisms. Now, what do we test 'em for?" "For their use as a means of air transportation," Morrow answered. "Primarily, that is—there are probably a good many other possibilities." "So how do we test 'em?" Smitty persisted. "How do you test any flight mechanism? You take it up in a plane, turn it on, and see how it works! So for thorough tests, including high-altitude performance, we'll need a plane with a pressurized cabin, big enough to hold our test equipment and the mechanisms. At the present market rates, you won't buy a plane like that for much less than fifteen thousand dollars!" Morrow was shaking his head, patiently. "We can't do it that way," he said. "But we can afford the cheap plastic materials they're using in small private planes, now, and build a ship especially for the mechanisms. Then we can test it for low-altitude performance and, if it works, gradually extend our tests on up to eight or ten thousand feet—" "And if the mechanisms fail, we crash! That'd be sheer suicide—" "Not necessarily. If they work at low altitude, they'll be dependable in saving us from a crash. And we can install a main and auxiliary system of mechanisms, so if one fails we can cut in another." Smitty paused, thinking it over. He gave a slow, grudging nod. "It might work, at that. It just might. But you realize what sort of predicament this will put us in, don't you?" "Such as what?" Morrow prompted cautiously. "Such as supposing somebody finds out about it," Smitty replied. "Most people have a pretty strong feeling about patriotism these days. We have something that qualifies as a good secret weapon. They aren't going to like the way we neglect to inform the government about it." "Uh huh. Men have been lynched for less," Morrow agreed. "We'll just have to see to it that nobody does find out about it. We can start out small, in almost any place that's relatively isolated—a deserted farm-house would do, I suppose—and build our ship. Then we'd have to make our flights at night, until we're fairly sure of the ship. After that, we could set out to find a permanent base—one hidden off somewhere in the desert or mountains, where nobody will notice us. Then we'll fly our equipment out there and set up shop." "What about power? If we set up near a power line, there'll be the company linemen coming around." "I think a gas-engine generator will suffice," Morrow refuted. "We can haul gas to our deserted farm-house by car, then fly it out to our shop at night." "What if somebody asks questions when we buy or lease this land, 'way off in the middle of nowhere?" Morrow grinned. "If it's 'off in the middle of nowhere,' why should we buy it? Nobody'll know we're there!" He finished the last of his coffee and shoved his cup aside. "You've been flying over the Southwest for quite some time, Smitty. I'm hoping you can find the sort of isolated spot we'll need." "There are places in that desert country where no white man's ever walked," Smitty confirmed. "They're still finding old Indian ruins nobody knew existed. But you know we could get arrested for all this, don't you?" "Umm," Morrow ummed. "Building an experimental aircraft without authorization is unlawful, isn't it!" "It's a federal offense!" Smitty exclaimed tersely. "Also, flying without a license is a federal offense—and you don't have one. And using government land without permission is a federal offense. And you'll have to quit your job with Western Electronics, won't you? What about your government contract?" "I've given them two-weeks' notice," Morrow explained. "I'm allowed that. Of course, engineers are scarce—so scarce that by quitting my job here for no good reason, I'm getting myself blackballed out of every other company in the industry. None of 'em will hire me after that." Smitty frowned concernedly. "Did you have to do it that way? I mean—suppose you just disappeared?" Morrow shook his head. "There'd be federal investigators swarming around here three-deep!" he said. "I repeat, chum—engineers are scarce! And they don't like strange things happening to engineers who've been working on top-secret material. They catch more enemy agents that way." "You sure they won't investigate you for quitting?" Smitty's gaze was thoughtful. "I don't think so. In the next two weeks, I think I can convince them that I've simply turned out to be a stinker." Morrow grinned sourly. "They'll be glad to get rid of me, then." "So you'll be ready to leave in two weeks." Smitty's tone was non-committal. "Then I'd better hop the next plane out this morning and start hunting up our base of operations." "Don't you want to come out to Westerton and see the mechanism?" "Uh-uh! Less we do to arouse suspicion, the better. I'll wire you, of course, when I find something. Have you got a gun?" "Gun?" Morrow started. "No. Why should I?" "Good." Smitty grinned lazily. "Don't carry one. They're too damned dangerous." "I agree," Morrow said quietly. "It hadn't even occurred to me." The train rattled and squealed through the hot summer afternoon, dust and foul-smelling smoke drifting back through the open coach windows. Morrow huddled in the corner of his seat and stared miserably out at the moving landscape. Have you got a gun? The words echoed through his mind. Of course he didn't have a gun. He had never thought about it. Why should he need a gun? But the answer was obvious. The secret of the gravity-control mechanism was precious. Certain individuals, should they learn about it, would stop at nothing to get it. Including murder. And if the government learned about it, they'd dump him into prison and throw the key away! Thus, anyone who happened to find out about it would do one of two things—try to steal it or inform the authorities about it. Either one would mean catastrophe. And there was only one sure way to keep anyone's mouth shut. Kill them! Morrow knew he couldn't do that—he didn't have that sort of mentality. Nor could he stand by and let anyone else do it, not even Smitty. But that was what Smitty had meant: he wouldn't stand by and let it happen, either. Besides, any murder would bring on an investigation. They couldn't hide from that. So it boiled down to the simple fact that if anyone found out what they were doing, they'd be finished. Dead men don't talk, but they get a lot of other people curious. Somehow, they had to keep it secret. They couldn't afford to let anyone find out about it. And that could be disastrous. There had to be some alternative choice, in case anything like that should happen. There had to be an out. Without one, they'd be trapped. They had to admit that some day, somehow, it would happen. Someone would find them out. And they had to be prepared to handle it. It would have to be handled in some way that didn't involve murder. What other way was there? There had to be some other way. Had to. Morrow chewed down his fingernails as the train lurched and rattled onward.... They pulled into Westerton with a hissing roar of steam and jolted to a stop beside the station. Morrow climbed down from the coach, wearily, and strode through the station to the street. It was late afternoon, but it was still hot. He pulled off his tie, stuffed it into his coat pocket, and unfastened his collar. Then he pulled off his coat, threw it over his shoulder, and rolled up his sleeves. That was better. Now for a bite to eat. He strolled down the shady side of Railroad Avenue toward Switzer's Cafe. Beyond the law! his footsteps rang on the sidewalk. Beyond the law, beyond the law— Suppose someone did find them out? They could ask no one to protect their interests. There'd be no help from the authorities. They'd have to protect themselves—against anyone and everyone! How could they do that without guns, without the possibility of killing someone? They couldn't accept defeat that easily. The secret was too important to the future of mankind! But what could they do? Beyond the law! Beyond the law— "Bill! Hey, wait up!" Morrow stopped as if someone had jerked him back on a string. He whirled toward the sound of the voice before his mind had recognized it. Gwyn came trotting down the street toward him, swinging a tennis racket in her hand. She was dressed in a white, short-skirted tennis suit. She stopped beside him, breathlessly, and put her arm through his. "Where you going?" "Switzer's," he said. "Join me in a sandwich?" "Okay." They strolled onward. Her skirt rippled over her smooth thighs, accentuating her tanned, slender legs. "I go on the four o'clock shift tomorrow. Want to come down at midnight and walk me home?" "At midnight?" he taunted. "Sure! It's the witching hour!" She wrinkled her nose up at him, teasingly. "What're you all dressed up in your suit for? Going somewhere?" "Had to go to Newark today," he said. "To meet someone." "Oh! Don't they even let you alone on Sundays?" "Sometimes, honey." He grinned. "When are you going swimming with me again?" "Well, if you want to swim—" She broke off and gazed up at him with mocking cynicism. Suddenly, her gaze went past him and she tugged at his arm. "Oh! Wait a second." She guided him into the little newsstand and left him by the cigar counter, going on over to the magazine racks. Morrow stood back and admired her firm, shapely posterior. "Ah!" she exclaimed, pulling out a magazine. She fished some change from the little purse on her belt and passed it to the newsstand operator. "Okay, let's go." "What've you got there?" Morrow asked. "You can see it after I have," she retorted. "Why don't you buy one yourself, for a change?" She flipped through the magazine's pages as they walked along. Morrow took her elbow, guided her around a telephone pole, and maintained a discreet silence. As they seated themselves in a booth, Gwyn closed the magazine and slid it across to him. Smiling, Morrow glanced down at it—then stiffened, staring at the cover illustration. It was no more than a typical science-fiction cover. The setting was a typical street scene at night—some dark side-street in the metropolitan section of some city like New York. In the foreground stood a young man.... But from there on, it was nothing ordinary. The young man was slumped back against the wall of a building as if he were trying to mold himself right into it. The expression on his face was one of mixed surprise, incredulity, and fear. It showed plainly that he knew no one else would believe him if he told what he was seeing; and furthermore, he didn't believe it himself. In the background, farther up the street, a group of people were emerging from a doorway. A beautiful girl was in the lead, and behind her came creatures that looked like men with blue skins, except that they had tentacles instead of arms. The light of a street lamp revealed the skin-tight garments they were wearing, and the octopus-armed men had transparent helmets over their hairless heads. The girl wore a helmet that was thrown back. And before them was a tall, gleaming rocket ship, standing on its tail-fins in the middle of the street! And the young onlooker didn't believe it! "She is pretty, isn't she!" Gwyn's acid tones cut through his thoughts. Morrow noticed, then, that the cover-girl's costume was not only skin-tight, but there wasn't much of it. He grinned wordlessly, then thumbed through the rest of the magazine. Its pages hardly registered on his mind. He was beginning to form an idea.... By the end of the following week, Morrow had convinced everyone at the labs that he was a heel. But that wasn't all. He also felt like a heel. It began the first day, with Borgesdorf. Alec Borgesdorf was chief of the Research Division. He sent word for Morrow to drop into his office. When Morrow walked in, he saw his letter of resignation on the desk. Borgesdorf was grinning and frowning at the same time. "What the hell is this, Bill?" he asked good-naturedly. "What's it look like, 'Greetings from the President?'" Morrow retorted. Borgesdorf's grin faltered. His frown turned to amazement. "Well holy cow, Bill!" he exclaimed. "What's the trouble? Why're you quitting?" "I'm quitting this whole blasted mess!" Morrow said flatly. "Does that answer your question?" "Wh—well, yes, if you say so. But—you know what this means, Bill! Why?" Morrow looked at him, coldly. "Suppose you mind your own business?" Borgesdorf tensed behind his desk. The friendliness faded slowly from his gaze. "All right," he said abruptly. "But if there's anything wrong around here, I think you should tell me about it." "Don't worry about it," Morrow sneered. "I'm quitting and that's that. Keep your dirty nose out of it." Borgesdorf's big, fleshy face reddened slightly, but that was all. He didn't say anything for a few minutes. Then he gave a barely perceptible nod. "Very well, Morrow. That's all." "Sure." Morrow wheeled and stalked out. Two days later, it was little Petersen. Petersen was a wizened, little guy nearly sixty years old; he'd been playing around with radio when it was a crystal and the cat's whiskers. He had consternation written all over his seamed face as he came shuffling up to Morrow. Morrow could almost hear the discussing that had gone on between him and Borgesdorf—Petersen frowning worriedly as the chief said, I couldn't get a thing out of him, Pete. Can't understand it at all. See what you can get out of him, will you? So here was little Pete. "Hear you're quittin' us, Bill," he drawled nasally. "What about it?" Morrow retorted, cursing himself mentally. Pete was a nice, old guy—everybody in the labs liked him. Morrow liked him, too ... but this was different. "Nobody's done anything against you, have they?" Pete complained. "You're throwing away a whole lot, son. It won't be gotten back easy." His shrewd, little eyes watched Morrow, pensively. "The country needs young fellas like you now, Bill—" Morrow forced the sneer across his face again. "That's just too damn' bad," he said evenly. Pete's eyes narrowed. "You're talkin' like a commie—" Morrow lashed out. The back of his hand smacked across the little man's mouth. "Beat it," he said huskily. "Beat it, you damned little shrimp." Pete stared at him for a moment, then turned slowly and walked away. Instantly, Mart Sumter came stalking across the lab. Sumter was big, broad-shouldered, with muscles bulging against his stained smock. He stopped in front of Morrow, his fists clenched. "If I ever see you do that again," he said softly, "I'll give you the worst beating you've ever had in your life!" Morrow returned his angry glare, then whirled and went back to his work. "You heard me, didn't you?" Sumter's breath whispered on his neck. "I heard you," Morrow rasped. "Don't forget it." Then Sumter strode away. Morrow grinned shakily. He was certainly getting what he deserved! At home, an idea was rapidly taking on form and dimension in his mind. He set up his drafting board, collected his inks, and worked doggedly through the night, etching out diagrams that showed—theoretically, at least—how his idea would work. At midnight, he would show up at Switzer's Cafe to walk Gwyn home. The nights were cool and pleasant, with deep shadows along the tree-lined streets and the street lights filtering through the treetops, dappling the silent fronts of the houses. They strolled along, slowly, their arms around each other, Gwyn's body pressed close to his. "I like a small town," Gwyn murmured softly, one night. "'Specially at night—so peaceful, so cozy." "I like the dark," Morrow said. "Why?" "I don't know. It changes things. It's a different world." She looked up at him, wonderingly. "I think of a small town. You think of a different world. Why is that, Bill?" "You're tired, maybe." He grinned down at her. "You've been on your feet eight hours." "That makes me think of a small town?" "Contentment," he said. "Small towns are contented." "And a different world—that's exciting, isn't it?" "Sometimes it's dangerous." "I see." She was quiet for a while. Then, "I never asked you where you were from, did I?" "No." "Small town? Or city." The latter held conviction. He chuckled. "You're not even warm! Casa Verde, Arizona. A cluster of shacks in the middle of a desert, with sand-stone cliffs rising like mountains of the moon everywhere you looked, and black buzzards circling in a hot, brassy sky—" She shuddered. "It sounds terrible." "—And beautiful." He murmured it, gently. "We left when I was six years old. No schools there." "Then—you're from a different world, is that it?" "You might say that." "Strange. We're two utterly different people, aren't we, Bill?" She was gazing up at him, studying his features, watching the dappled light and shadows play over them. Morrow sensed that he was on perilous ground. He said nothing. "You aren't happy here, are you, Bill?" she spoke almost in a whisper. "You never will be!" "Most men I've met are—searching for something," he replied hesitantly. "But they don't devote all their time to it," she protested. "They at least manage to live fairly normal lives and raise families—" "Do two utterly different people—" He broke off, leaving the question unspoken. But we're down to brass tacks, now, he mused. We just don't feel the same way about things! Why was that? "Look," he said, almost gruffly. "I think of a different world—let's stick to that point, for now. You think of a small town. But then, why do you read science-fiction?" She frowned in puzzlement. "What do you mean?" "Well, isn't that a 'different world?'" "But it's fiction. I don't think of reality—" He smiled gravely. "You don't think there are horrible monsters lurking in the corners, or little people in the wallpaper, or strange eyes floating around watching you—" "If I did, I'd be in a booby-hatch!" "Or you might be a research engineer!" He chuckled softly. "Ignorance is bliss, Gwyn. And how much do you know about reality? What do you know of the mysteries within the atom, or the strange way the Universe seems to be expanding as if it had exploded and the stars, including our sun, were still hurtling outward from the blast?" "Sounds like a good way to go crazy!" She looked up, intently. "I've never heard you talk like this." "Well, you aren't quite so ignorant," he amended teasingly. "You realize inwardly that your 'small town' isn't quite so contented as it seems—that beneath the surface, there's unrest. So maybe you read science-fiction because it deals with spectacular forms of unrest—men risking their lives in space travel or on other planets, changes and developments that cause revolutions or wars—and you find solace in that. The little unrest in your 'small town' no longer seems so bothersome." "Mr. Morrow," she spoke icily. "I do not enjoy having you pick my mind apart!" Then why must you criticize me? he thought. But he didn't say it aloud.... Sunday afternoon, they went swimming. There was a secluded strip of beach where Morrow spread a blanket out on the sand, and after they had swum and splashed and dived to near-exhaustion, they sprawled themselves out on the blanket and let the warm sun dry their skin. Gwyn lay on her stomach and removed her halter, then rolled her trunks into a narrow band around her thighs. Morrow watched with mingled interest and affection. Gwyn scowled at him, then pretended to ignore him. When his skin began to sting through the sun-tan oil, Morrow suggested they move into the shade of the trees. Gwyn struggled back into her halter and sat up. They dragged the blanket back into the shade and sat down again. Morrow put his arms around her, and they talked for a while. When Gwyn came out of the bushes wearing her shorts and blouse, she grinned and wrinkled her nose at him. "This has been wonderful, Bill. I almost wish we could be like this forever!" She let him kiss her, then. They rode back to town on his little motor-bike and had cokes and hamburgers at a lunch-stand. The second week passed without significance. The other engineers at the labs treated him coolly, now. They'd be glad when he left. At home, his diagrams were finished. He went over them again, checking them thoroughly. Friday, a telegram reached him at the labs.
Saturday, he spent most of the day settling his affairs and packing for the trip. The plan had begun. Whether it worked or not, he was going through with it. The gravity-control mechanism would not be turned loose on the world to increase the tensions and fears already much too prevalent to the point where mankind would plunge into atomic war. But the gravity-control mechanism wouldn't be abandoned, either. They'd develop it, secretly. They'd have it ready when the world situation changed—for the better, Morrow hoped—and it could be given to the world. Then, mankind would benefit from it. That was his whole purpose—that his discovery should benefit mankind, rather than pave the way to the destruction of civilization. Morrow considered it a purpose worthy of all the sacrifices he had to make. His job, his career—perhaps later, if the plan worked, he could regain them. But he had to try. The battered, worn truck came whining out of the rutted dirt road, clashed its gears, and rumbled into the wide sawmill yard. On the left, a little mountain stream laughed merrily over the rocks and then widened out, ahead, and trickled sluggishly across a brakish pond. On the right, at the foot of the tall pine trees, were the crumbling ruins of sheds and outbuildings, piles of rotted wood. The truck halted before the main sawmill building across the yard. The mill was weather-stained and decrepit-looking, with the boards fallen off one wall and the roof sagging on one corner, but it was still standing. Morrow and Smith climbed down from the cab of the mud-splattered truck and stood gazing around them. "Looks like she's been abandoned for quite a while," Morrow remarked noncommittally. "She has," Smitty agreed. "But it'll serve our purposes, I think. This main building is large enough to be our hanger-workshop with a minimum of repairs. The timbers have tightened up until they're like iron, else the whole building would've collapsed long ago." Morrow nodded. "Long as the timbers are sturdy, we can patch up the holes with canvas tarpaulin if we have to." Smitty hooked his thumb toward the stream. "I got a lab analysis of the water—it's drinkable. But we'll have to spread some oil on that pond to kill the mosquitoes. We don't have any neighbors to worry about within ten miles of here; Yosemite National Park's due south of here about fifteen miles." "What about fire towers?" "Forest rangers? The nearest is over on a mountainside twenty miles away. He's not going to see anything at night unless it's a fire." Smitty grinned reflectively. "I figure this can serve as our temporary base until we get the ship built and flight-tested. Then we travel due east across some of the worst desert and mountain country you'll ever see, to the site I've picked for our permanent base. It's in a deep, crooked canyon over on the other side of the Kawich Range, in Nevada." "Not near any atomic project area, is it?" "Uh-uh. Not near anything else, either. It's not near any airway routes, and private pilots shun that area because there aren't any fields or meadows available for emergency forced-landings." "Sounds good!" Morrow complimented him. "Where do we camp, here?" "I've knocked together a small cabin back in the woods. Grab your stuff out of the truck and come on—I'll fix us some chow!" Morrow climbed into the rear of the truck and slid his luggage back to the tailgate. Smitty took a couple of suitcases, Morrow the third and his equipment case, and they strode off on a narrow trail winding through the trees. "Now what was it you've been working on?" Smitty asked as he led the way. "I've been working, on?" Morrow echoed blankly, his mind filled with sensations of clear, cool mountain breeze and the smell of tall pines and the eternal silence of the woodland. "Yeah!" Smitty prompted. "When we were having dinner, back in L.A., remember, we were talking about the event of anyone catching us at this, that we'd be finished if they did? You said you'd been working on something that would protect us from discovery." "Oh, that!" Morrow grinned. "I merely figured out a means of camouflage." "Camouflage?" "It's still just in its theoretical stage, but I think it'll work. I'll show you my diagrams." "Show me while we're eating." The little shack nestled under the pines was cozy and weather-proof, built out of rough lumber and fitted out with hand-made furniture. The air was filled with the aroma of fried bacon, coffee, and wood smoke. They sat at the small, wooden table and ate out of tin plates, washing it down with tin cups of coffee, and Morrow spread his diagrams between them and explained his idea to Smitty. "—So it's all designed around that propulsion unit," he said. "The gravity-control ring establishes a focus of 'false gravity' inside the tail-pipe so that air is sucked in through the scoops on the ship's hull. The air 'falls' into that focus of 'false gravity' and goes on past it to shoot out the tail-pipe at an estimated sixty-mile-an-hour gale." "Couldn't we do just as well with a large electric fan?" Smitty asked, half-jokingly. "This propulsion unit will cost only a fraction of the price of a large air-conditioning fan and motor," Morrow pointed out. Smitty grinned at the diagrams. "Okay, but you've certainly sketched in a fancy-looking ship, there! Aero-dynamically, I'm afraid it wouldn't be too practical—" "I know," Morrow admitted. "But we'll have to work that out and still keep this fancy-looking ship." "How come?" "Because that's the whole idea, Smitty! Think a minute. Suppose we've built our ship and are flight-testing it. So there's always the possibility that someone will see it—" |
