"—And call the cops!"
"Right. Normally, that would bring on an investigation and we'd be finished."
"I hope they serve good food at Leavenworth!"
"Stop interrupting, will you? Now, the idea is this: suppose whoever sees usthinksthey're seeing a shipfrom outer space?"
Smitty's grin faded. He stared at Morrow for a moment, then picked up his cup and took a healthy swig of coffee. "I see what you mean," he said, replacing his cup carefully on the table. "They think they're seeing a rocket ship from Mars, or something like that. So they go to the cops and start yelling about it. And that's happened so often—"
"We won't have to worry about any thorough investigation," Morrow concluded, smiling. "They might check the area in which our ship was sighted—"
"Which isn't likely to be around here!"
"—But that's all. Even if it is around here, they aren't going to ask us too many questions so long as we don't have two heads, blue skin, and arms like an octopus!"
Smitty chuckled mirthfully. "You'd better keep out of sight, then!"
"Cut the quips!" Morrow growled mockingly. "I think the idea will work. We'll just have to design the ship so it looks weird enough to excite the imagination. It may have some aerodynamic faults, but it's worth the trouble."
"We can't make ittoofancy," Smitty warned. "It's still gotta fly!"
"We don't want it too fancy—just so itlookslike a spaceship! First thing we'll have to do, though, is check the costs of plastic construction materials for aircraft." Morrow gulped the last of his meal down with a swallow of coffee, stacked his cup, plate, and utensils, and set them aside. "We don't want to go too deep into our capital to build this ship," he said wryly. "The lease on this property has already soaked us two thousand."
"What'll the shop machinery come to?" Smitty asked pensively.
"Around a thousand, I think."
"Then I think we can build the ship for around—well, anywhere from one to three thousand dollars. At the most, that'll be just over half our capital down the drain." He frowned. "What'll the rest of it be for? Operating expenses?"
"Mostly that. There are a few other ideas I'd like to try out, though—experiments with these mechanisms. But remember that we're dedicated to this thing until the world situation changes and we can turn it loose without any risk. That may not come for years!"
"I've thought about it," Smitty retorted, grinning. "There's a deer run over near our Kawich mountain hide-out, and other game is plentiful. Our meat supply for the next hundred years costs no more than the price of a couple of hunting rifles."
Morrow shook his head. "That might be fine, Smitty. Maybe we could plant a vegetable garden, too, and live off the land. But I don't think we should subject ourselves to the life of a hermit. We've got to keep our perspective with this thing, and not get anti-social about it."
"A hermit's life would get kinda boring, anyway," Smitty conceded. "But I can always go back to crop-dusting and make a few dollars now and then. What'll you do, though? Can you get a job?"
"I know electronics!" Morrow smiled grimly. "I suppose I could open up a little radio repair shop somewhere."
"You? A radio repair shop? The first real genius this country's had for—" Smitty broke off, staring at him.
Morrow stared back, scowling. "Genius?" he echoed. "What in hell ever gave youthatidea?"
Smitty grinned faintly as he lighted a cigarette. "Guess I'm just carried away by your two heads," he said, spewing smoke.
It was a full month's work just to purchase the shop machinery, the building materials to patch up the old sawmill, the materials for the ship's construction, and to truck it out and install it in the building. They worked from daylight 'till dark, then retired to their shack and spent most of the night going over the blue-prints for the ship. Gradually, it took shape and form on paper.
Masses of cloud were banked against the surrounding mountains, covering the sky with a solid, gray mass that shook loose a thin drizzle of rain, just enough to dampen the ground, the morning they conducted the first weight-test.
They used the gravity-control mechanism—they called it agravitorby then—which Morrow had built in Westerton. The test was conducted outside, with a sling suspended under the gravitor to support a pile of sandbags, with a rope hanging from its bottom to a small hand-winch on the ground.
The gravitor rose up into the drizzle with its load, lifting three hundred and sixty-nine pounds to a height of forty feet. It floated there, the rope dangling loosely from it. There was an odd three-foot S-curve in the rope just below the sandbagged sling.
Smitty stared up at it, squinting against the misty rain. "It just floats there!" he exclaimed huskily. "On four flashlight batteries—"
"The wind's drifting it toward the trees," Morrow said in a tight voice. "Better take up the slack."
Smitty stooped and wound up the little hand-winch. Then he straightened and stared upward again. "On four batteries," he repeated in his husky murmur. "Look at that snake-twist in the rope!"
"That part of it's inside the gravitor's field," Morrow explained quietly. "As for the batteries, I think it's because the mechanism is shielded from the gravity and magnetic influence of the earth. It works entirely within its own magnetic field. Its electronic conductivity is more efficient, so we're getting far more power from those flashlight batteries."
"Butisthere that much power in a flashlight battery?"
"Don't forget those batteries are also inside the gravitor field," Morrow reminded him. "Anyway, I'm not even sure that's the answer. The scientific implications of this extend to such matters as the dimensions and volume of the Universe, and the speed of light. Maybe the Universe isn't expanding and maybe light 'particles' or 'congealed energy' or whatever they are don't slow down. Maybe they curve through a kaliedoscope of gravitational forces generated by star-clusters, and the 'expansion' is a matter of refraction in our particular sector of space—"
"Do you have these attacks often?"
Morrow looked down to find Smitty watching him with a mocking leer.
"C'mon, professor," Smitty chided him. "Let's crank this thing down and get in out of the rain."
"Ummm? Oh—all right!"
Crude wooden jigs were sawed out and nailed together. Plastic tubing was heated and curled into the jigs and, when cooled, was taken out in the precise shapes of formers, spars, and bulk-head frames. These were welded onto thick plastic rods and the rough outline of the ship began to appear. More rods were added, strengthening the framework, and the ship began to assume its final shape in a spidery basket-work of glistening, transparent plastic.
The covering was torn off a large roll of celatex film, and long strips of it were spread through the inside of the framework and cut to size. The strips were dipped in a softening bath, then stretched across the inside of the framework, pressed against it and, drying, molding to it to form a tough, rigid inner skin. Fistfuls of plastic insulating material was dipped and sponged into the openings in the framework, molding to it and to the inner skin. Then more strips of celatex were cut to size over the outside of the framework, dipped, and stretched over it to form a strong outer skin. The result was a large, sleek hull, with a shimmering basket-weave framework and frosty-white, fuzzy insulation showing through its transparent skin.
Gravitors for the lift units and the propulsion unit were built, tested, and installed. A cargo deck was built into the belly of the ship, accessable through large side doors. Power circuits and control systems were installed. The forward, control pit, and aft compartment decks and bulk-heads were welded into place. Then they let their imaginations run riot on the interior decoration, fittings, and furnishings which were easily constructed of plastic framework with celatex stretched and pressed firmly over it to form the desired curves, bulges, and flowing lines. Then they went over it with sand-paper, paint-brushes, and dark blue and mirror-chrome plastic lacquer.
The interior was, to put it mildly, luxurious and ultra-modern. Smooth, flowing instrument panels and storage lockers molded into the walls, foam-rubber chairs growing out of the decks, bunk-seats sunk into the bulk-heads, and transparent-topped tables sprouting their chrome frames from the fore and aft lounge decks. They finished it up with a small lavatory and an electric hot-plate in the bulk-head cubicles just off the forward lounge.
Finally, transparent plexiglass was fitted into the long port-hole slots along the hull, and a large plexiglass dome was mounted over the control pit above the smoothly tapered nose. Then they papered the plexiglass and manned a spray-gun, giving the entire outer skin a thorough coat of shimmering black lacquer.
The complete construction took all of six weeks working from dawn to well after sunset. When it was finished, Smitty took the truck and went into Stockton to purchase the three automobile batteries which would be used to power the ship.
That night, Morrow sat at his drafting table scrawling rough diagrams and pencilling in mathematical notations around them and on the back of the papers. His table lamp threw a bright pool of light in the corner of the dark, shadowy workshop. The night was completely silent, save for the distant sighing of the wind through the pines outside, the faint scratching sound of his pencil, and the clicking and whispering of the slide-rule in his hands when he paused to compute some factor in the diagrams.
Building and weight-testing the gravitors that went into the ship had led to speculation of other possible uses of the mechanisms. The possibilities were many, and Morrow spent his spare-time working them out. His ability, however, was limited.
First, there was the electronic efficiency of the gravitors, the increased power gained from battery storage-cells, the decreased loss of power within the circuits and mechanism. If electrons worked more efficiently in a gravitor's field, then mechanical and chemical power might work just as well. It appeared, on paper, that a small, one-horsepower gasoline engine might deliver the equivalent of a hundred horsepower or more in electrical energy, if it were incorporated into a gravitor field. Morrow worked this "gravitor engine" out the best he could, cursing his lack of knowledge in mechanical engineering. It might work, but he didn't have the knowledge to tell exactly how it could be made. It wasn't his line.
Then, there was the possibility of using the increased gravitor-field efficiency in radio communications. This was right up his alley, but the implications went so far and so deep that only a thoroughly experienced and trained scientist could trace all of them. He hadn't been an engineer long enough to have acquired that much training and experience; he wasn't a renowned scientist in the field. He couldn't always be sure where he was right or wrong in his computations. This was pure research; no book had ever been written for it. He couldn't look up all the answers.
But it appeared that a small radio set would have the power to reach anywhere in the Solar System, not to mention the extensive refinements of any television and/or radar set-up.
The possible refinements of chemical catalysts and electro-chemical processes were extensive, too. Staring at his diagrammatical results, Morrow wondered if mechanisms couldn't be perfected to measure the taste of foodstuffs as the taste-buds in the human mouth did, to measure the smell of odors as the human nose did, to convert carbon-dioxide into oxygen as plants did—even mechanisms which would react selectively to the electrical impulses generated by the cells of the human brain!
But he wasn't a chemist. He could only guess at the possibilities.
Finally, there was the possibility of applying the gravitors directly to the problem of transporting the human body by air. Part of this, he could answer: a gravitor strapped to a man's back would more than replace the conventional parachute for emergency bail-outs. The gravitor could be hooked into alternate power-circuits with alternate field-transmission coils, so if it failed to work on one setting the wearer could switch it to another, the equivalent of wearing a second parachute in case the first failed to open. And unlike a parachute, the wearer would have complete control over his rate of fall: he could descend gently to the ground or, if he wished, he could stop and hover in the air or even reverse his descent and rise upward.
That was part of it. Morrow had discussed it with Smitty and they'd decided to incorporate it into their project. In addition to having the ship look like something from outer space, there was also the problem of having to make a forced-landing somewhere. They might be seen on the ground, repairing their ship. The gravitors could be built into a tank carried on their backs, and fastened to a special harness costume complete with transparent helmet fitting over their heads. The helmets would protect their faces from the wind in a bail-out. Also, their appearance would be altered just enough to make them seem to be visitors from another planet, beings who did not breathe Earth's atmosphere.
But that still didn't give the human body a means of transportation by air. A small, portable propulsion unit was needed for that, and Morrow wasn't at all sure he could design such a unit. He was not a jet engineer.
He wasn't too sure about the large propulsion unit in the tail of the ship, either. Basically, it was a ram-jet unit. It ought to work, but it might not work too well....
Morrow tossed down his pencil and slide-rule, sighing, then pressed his hands over his aching eyes and rose from the table.It's too much for one man!he thought bitterly, and dropped his hands to his sides.
He stood gazing into the deep gloom of the workshop, at the huge, black hull gleaming softly in the darkness. Fifty-five feet long and fifteen feet high, the ship rested patiently on the narrow runners that supported its sleek belly. Twenty-five hundred dollars and six weeks of cautious, painstaking work rolled into one beautiful, fantastic-looking black monster with curved fins around the cluster of "rocket" tubes in its tail and streamlined, submarine-type diving vanes near its nose. Those vanes had been Smitty's contribution, operating on a cross-control system to bank the ship and lift it around a turn as the aileron-elevators did on flying wing aircraft. No other control surfaces were installed; the long, sleek rudder fin was immovable.
The night wind soughed through the forest on some nearby mountain slope. The ship stood black and silent, gleaming softly in the deep gloom of the workshop. It was a weirdly beautiful thing, like some creature of the Unknown.
Straight out of the science-fiction magazines!Morrow mused, grinning.If Gwyn could only see it—
A vision of her rose into his thoughts: Gwyn, lying on her stomach, the tight roll of her swimming trunks about her thighs, the smooth, tanned skin of her slender body, the firm swell of a breast beneath her armpit, the sunlight glints on her brown hair and the cool, calm wariness in her eyes....
Morrow grimaced wryly. Gwyn again! He'd been thinking entirely too often of her, and too much, since he'd left Westerton. He kept telling himself she was just another of the sacrifices he'd been forced to make, another part of his life he'd had to deny himself—
Still, when he slept he dreamed.
He was just too damned young, he told himself harshly. The demands of his body were strongest at his age; it wouldn't let him alone. His instinct to mate, to reproduce his kind, demanded satisfaction. There was danger in that. If he fought it, denied it, kept it bottled up inside him, it could spread and infest his whole being until it became a perverse fixation on sex. He had to have some outlet for it. Time off from his work, time to relax and enjoy female companionship, the nearness of a woman. An older man, in whom the mating lust had had time to diminish until it wasn't quite so strong and insistent—an older man could retire and live in an ivory tower of science. He couldn't. He must make allowance for it.
Find himself a girl in town. A date, a little moonlight and soft talk. Forget about a girl three thousand miles away. Forget Gwyn....
But he wished she were here. He wished she could see the ship.
Dawn was etching its rose-colored light in the East when Smitty drove in the yard.
They installed the batteries and climbed out through the simulated air-lock entrance to the ship, peeling off their gloves and shoving them into their hip pockets. Smitty turned, wiping his hands on his coveralls, and looked up at the ship.
"We can ground-test her without taking her outside," he said plaintively.
Morrow picked up his mackinaw and slung it over his shoulder, grinning. "Can't you wait 'til tonight?"
Smitty scowled at him. "Suppose she doesn't check out? Then we'll spend the rest of the night overhauling her! We oughta give her a ground-test right in here, Bill."
"Fair enough—if she doesn't go through the roof! But let's wait 'till after breakfast, anyway." He walked over to the stove, checked its fire, and shoved a couple more sticks onto it to keep it burning until they got back. "C'mon," he prompted, heading for the door. "I'm hungry if you aren't!"
They left the workshop and crunched through the brittle ground-frost to their shack. Morrow took his turn as cook, whipped up a batch of sausage, eggs, and pancakes, and boiled the coffee to the strength he preferred—which Smitty diluted liberally with canned milk. They gulped down their breakfast, cleaned the dishes, and strode deliberately back to the workshop. The chill November air bit into their clothes, but neither hastened his pace.
As they entered the warmth and shadow of the workshop and pulled off their coats, Morrow felt a fluttery sensation in his stomach which he carefully neglected to mention. It was probably indigestion, anyway.
Smitty, too, was silent. He tossed his coat on the workbench, strode straight to the open air-lock door, and clambored up into the ship. A tight grin creased Morrow's face as he followed with what casualness he could muster.
They moved through the luxurious forward lounge and climbed the metal steps into the control pit. Smitty slipped into the pilot's seat behind the controls and flight panel, up forward. Morrow took the flight engineer's seat behind the instrument console, on the left side of the transparent blister dome. The console sloped gently, like a desk-top, its surface glittering with a dozen instrument dials, twenty-four switches, forty-eight signal lights, two knobs and master switches, and a jet-blast temperature gauge.
"Flight station checks," Smitty reported quietly.
"Roger." Morrow swept his hands across the console, flipping on the twenty-four switches. "Stand by for gravitor check," he added, then clicked on the two knobs.
The ship shifted slightly beneath them. The faint, sighing sound of wind came from the tail.
On the console, twenty-one signal lights flashed blue. Three flashed red. Morrow scowled at them.
"Report gravitor check!" Smitty prompted impatiently.
"Three gravitors out," Morrow growled. "One auxiliary lifter, one auxiliary and one main drive gravitor. Must be a short in 'em somewhere."
"We don't need the drives for a ground-test," Smith reminded him. "Cut to main lift units and let's try her out!"
"Wilco." He switched off the drive knob and the twelve auxiliary lifter switches. "Stand by to rise!"
The sighing wind was gone from the tail. He gripped the lifter knob in his fingertips and, turning his head, stared out at the dark floor of the workshop below.
He turned the knob, cautiously.
The ship rocked gently, then lifted. The floor dropped away beneath them.
"Watch it!" Smitty warned tersely.
The ship paused, then seemed to settle.
They floated serenely, twenty feet above the workshop floor. The heavy rafters of the roof loomed close over the transparent blister.
Smitty cleared his throat, nervously. "I think that's high enough!" he exclaimed.
Morrow permitted himself a fleeting grin, then began to inch the knob back toward its stop. "Stand by for descent!" he warned.
The ship settled slowly. The floor rose up with majestic deliberation—then paused again.
"How high are we?" Morrow asked.
"A little over four feet on the altimeter," Smitty replied. "Want to hold her here a while?"
"I want you to climb out and see how much it alters her lift," Morrow explained. "One less passenger shouldn't affect it at all, but let's make sure."
"Wilco." Smitty rose from his seat and came back toward the steps.
"Jump around a little," Morrow said. "See if it rocks her any."
Grinning, Smitty banged noisily down the steps and clattered back through the ship. She rode perfectly still, unmoving. Smiling his satisfaction, Morrow waited.
Then Smitty walked around the bulge of the nose, on the floor below, and waved to him. Morrow waved back and, rising, moved up to the front seat. The altimeter still registered slightly over four feet. He returned to the console, sat down—and snapped off the lift knob.
The ship settled immediately to the floor, struck lightly, and rocked to a standstill. Morrow clambored down the steps and felt his way back through the dark interior to the air-lock.
Smitty was waiting for him as he dropped to the floor. "She checks, doesn't she?"
"She checks," Morrow affirmed. "Now let's get to work on those shorted gravitors!"
The first night's tests were preliminary. They lifted the ship a few feet off the ground and flew it across the sawmill yard and back. They switched the gravitors from main to auxiliary systems. They loaded the cargo deck amidships with sandbags and flew a weight-test. They took the ship up to fifty feet and held it there until the wind, blowing them toward the trees, forced them to come down.
The ship checked out in every test. They decided to make the first trial flight the next night.
Morrow sat up in the co-pilot's seat beside Smitty as they drove steadily through the darkness. Above, the stars twinkled coldly in the black heavens and the white sickle of a quarter-moon threw its milky glow into the control pit. Below, rolling gray stretches of meadow spread out between dark, timber-clad shoulders and humps of the Sierras. To the East, the timber gave way to rocky, cloud-wreathed peaks. They were headed toward them, and climbing.
"Five thousand on the altimeter," Smitty remarked flatly. "That's ten thousand, five hundred above sea-level. She isn't levelling out yet." His face was grim in the green glow of the instrument dials.
Behind them, the black, glinting hull was crammed with sandbags. They were lifting a full load.
Morrow kept his gaze fixed on the air-speed indicator. A deep, whooming sound came from the tail-jets. The needle on the indicator dial flickered restlessly, back and forth, over a single point.
They were doing forty miles an hour, indicated air-speed. They hadn't been able to increase that speed. A brisk twenty-five-mile-an-hour wind was blowing them steadily southward off their course.
Smitty shook his head. "Those jets don't evensoundright, Bill—"
"I know," Morrow said. He sighed wearily. "We've got to do better than this. Take her higher—ram-jets are supposed to work better at high altitude."
"I don't want to go over twelve thousand without oxygen," Smitty replied. "Can't let this wind blow us down over Yosemite National Park, either—if we can help it."
"Take her up," Morrow said.
The ship continued to rise, steadily.
"Eleven thousand," Smitty chanted. "Eleven thousand five hundred, twelve thousand, twelve thousand five—she's flattening out!"
Their ascent slowed, gradually. The ship steadied at thirteen thousand feet above sea-level—7500 feet on the altimeter, which had been zeroed to the altitude of their sawmill workshop.
"Down!" Morrow barked. "She's losing speed!"
The indicator needle was creeping back past thirty-five, then thirty—their sideward shift to the south could be felt. Smitty shoved forward his control wheel. The ship dived.
They glided easily back across the mountain slope toward their sawmill. Judging their wind-drift accurately, Smitty set the ship down in the yard before the black, yawning doors of the building. As the runners scraped the ground, he switched off the gravitors and slumped back in his seat, dejectedly.
"We've got to rebuild that jet chamber," he muttered. "There's something wrong with it, Bill. All we've got is a big wind-blower, in spite of her weightlessness—the drag of the hull wouldn't slow us downthatmuch!"
Morrow unbuckled his seat-belt, rose, and strode back to the steps without a word.
It took them a week to pull out the rear bulk-heads and completely redesign and reconstruct the tail-jet assembly. When they finished, they tried it again. They got an air-speed of seventy m.p.h. at low level, but it dropped to twenty m.p.h. as they gained altitude. The tail-jets didn't just make a whooming sound, this time—they made a rumbling, burbling sound.
They landed and pulled the ship into the workshop, closing the big doors after it. Morrow walked over to the workbench, pulled off his gloves, and threw them down.
"It's no good!" he said harshly. "That jet chamber just isn't shaped right—there's too much turbulence in it, breaks up the jet-blast."
"We'll rebuild it again," Smitty said, with a shrug in his voice.
Morrow wheeled and glared at him, red-eyed. "We aren't jet engineers, Smitty. We're building by guesswork! We can redesign that jet chamber a thousand times and never get the right shape!"
Smitty moved on to the stove and began stoking up the red coals, stacking wood on them. "She does seventy per hour up to seven thousand feet," he said dully. "If that's the best we can do, we'll just have to be satisfied with it."
"It's notgoodenough!" Morrow protested. "Shehasto have more speed, Smitty. She'll be at the mercy of every wind that comes along if she hasn't, weightless as she is!" He smacked his fist into his palm, decisively. "We've got to get help, chum."
"Help?" Smitty turned and looked at him, querulously. "Where can we get help?"
"A jet engineer," Morrow snapped irritably. "That's the only one whocanhelp us. We've got to find one—" He broke off, suddenly thoughtful.
Smitty grinned without mirth, mistaking his silence for hopelessness. "That's the trouble, Bill," he said. "There's no one whowouldhelp us!"
"I'm not so sure about that!" Morrow replied softly. "I'm not so sure at all—"
It was late Friday afternoon when Morrow parked the battered, mud-splattered truck on a side-street and climbed out to go for a quiet stroll in suburban Sacramento.
The street address he was looking for turned up in the next block, near the edge of town. It was an inconspicuous one of the long street-row of small houses with a green lawn stretching down to the curb and dotted with a few evergreen shrubs, a broad livingroom picture window in front, a white front door with a small ornamental iron night-lamp mounted above it, and a one-story, red-tiled roof in the flat, gently sloping California style.
Morrow walked past the house and around the block to the alley. He walked up the alley behind the house. Its rear was as inconspicuous as its front: a wide yard, partly in lawn, partly in flower garden and part gravelled with clothesline, enclosed by a low, whitewashed wood fence. The only noticeable difference was a small sand-box in which a small brother and sister were playing with toy cars. The little boy and girl wore matching rompers and had straw-colored hair which, Morrow concluded, they must have inherited from their mother. He'd never met Mrs. Foster, but he remembered Bob Foster's dark, heavy hair.
He walked on down the alley, studying the back yards behind the other houses. He noted how wide the alleyway was, how high surrounding fences, garages, and other obstructions were, and the lack of telephone poles or wires overhead. He nodded his satisfaction.
When he got back to the truck, he took a street-map from the glove compartment and carefully marked the exact location of Foster's house.
Then he drove out of Sacramento, had dinner at a roadside restaurant, and proceeded to Stockton. Smitty met him downtown and they went into a lunchroom for coffee.
"Groceries and laundry's taken care of," Smitty reported wryly. "How was Sacramento?"
"Fine," Morrow said. "If the weather forecasts for tomorrow night pan out, we'll get in and out without any trouble."
Smitty frowned worriedly. "It's still a big risk to take, Bill. We'll be flying into the Coastal Radar-Defense Zone, you know, and we can't just file a flight-plan at an airport for an unauthorized, illegal ship. I'd hate to look up and see an F-140 night-fighter with its nose-cannon blazing at me!"
"That ground radar isn't effective below three thousand feet," Morrow reminded him. "I think we can sneak in at treetop-level without being detected."
"That's all right, unless we fly into a power-line in the dark," Smitty grumbled. "It's still risky as hell—"
"We've got to have Foster," Morrow said firmly. "I can't say for sure whether he'll join us or not, but we've got to try!"
"Okay!" Smitty signed resignedly. "We'll try."
The following night, Morrow left Smitty checking over their ship and flight equipment and drove the truck down to a gas station on the highway, thirty miles west of their sawmill-workshop. He parked beside the gas pumps, told the attendant to fill the tank and check the oil, and went inside to the pay-phone booth.
He called Sacramento Long Distance and gave them Foster's home videophone number.
There was some fault in calling from a pay-phone, of course—and a Long Distance call on a rural pay-phone at that. Neither Long Distance calls nor pay-phones nor rural phones had the new videophone accessories. Videophones, involving two-way television transmission via a camera-screen installation, were still in the development stage. Metropolitan and suburban phones had the video screens. Long Distance coaxial transmission was still too costly to merit the installation of the screens on rural phones—which also ruled out Long Distance video calls. To install the screens in pay-phones would, as yet, triple the cost of the calls.
Naturally, the Sacramento operator would inform Foster this was a Long Distance call; Foster's screen would remain blank. The gas station's pay-phone had no screen. This was a disadvantage to Morrow: not seeing Foster's face, he wouldn't be absolutely certain he was speaking to Foster. He'd have to rely on his memory of Foster's voice, and it had been more than two years since he'd met Foster.
Positive identification could be important. Morrow kicked himself mentally for not making a local call to Foster's home while he was in Sacramento. Suppose Foster had moved in the past two years? Suppose there was some sort of slip-up that aroused someone's suspicions just enough to start the authorities on an investigation—
Even theslightestmistake might finish them!
And the call had to be made. Their plan was set for tonight, Saturday night, because Foster was most likely to be home from work—research engineers often worked late hours on weekdays—and because he'd probably have the next day off. They had to get Foster out for that one day, and it had to be done right. But they had to be certain that Foster was home when they went after him.
The receiver continued its rattling noise in his ear as Morrow waited, fidgeting impatiently, and the seconds crawled past.
The rattling ended with a faint click.
"Hello?"
Morrow exhaled a shuddery sigh of relief. He recognized Foster's characteristic deep, muffled tones almost at once. "Hi, Bob. This is Bill Morrow—"
"Morrow? Well, hi yourself! Where you calling from?"
"I'm on the highway," Morrow said. "I'm on my way north and wondered if I might drop in as I pass through Sacramento—I ought to be there in a few hours. You going to be home?"
"Ye-e-es. C'mon around, by all means! You still have my home address, haven't you?"
"Sure thing. How've you been?"
"So-so, between drawing curves on flight-test characteristics and pounding out stories. You written anything lately?"
"I've been a little too busy to give it much thought," Morrow answered truthfully.
"Uh huh! Well—say, you going to be in 'Frisco for next year's science-fiction convention?"
Morrow grinned. "'Sa little too early to say, yet. I'll see you in a few hours, then, huh?"
"Right-o! We'll have the beer on ice!"
Morrow drove back to the sawmill workshop and helped Smitty perform a final inspection of the ship and equipment. Their plan was worked out thoroughly. The ship would fly to and from their target at low altitude, and at its maximum speed. The forecast weather conditions would aid in hiding them, but it would also hinder their flight—much of it would have to be done on instruments, and Smitty spent considerable time studying topographical sector-maps and radio omni-range vectors.
Their personal gear consisted of two special suits which would serve to conceal their identity as well as aid them in an emergency. The suits, patterned out of shimmering fabrilastex material, fit with skin-tight snugness over their long winter underwear and socks. The foot-soles of the suits were of springy foam-rubber, heat-welded to the fabrilastex just as the seams in the material were heat-welded to a perfect fit. A sturdy harness fitted into the inside of the suits to grip their legs, thighs, and chests, suspending them in bail-outs from the sturdy plastic tanks on the back of their suits. Each tank enclosed a gravitor unit. A lightweight, transparent blue dome helmet fitted over their heads and clamped onto fasteners on their shoulders. There were small air-vents around the bottom of the helmets and in the fantastic-looking knob attachments in their tops.
They pulled on their suits in the workshop and stared at each other, grinning. "All you need," Smitty taunted, "is a flashlight ray-gun in each hand!"
"You look pretty monstrous yourself, blue-face!" Morrow retorted.
"Youlooksexy, old boy!"
"Down, Rover! Better climb on the ship's radio and check the weather reports again—"
"Wilco!"
Morrow walked to the end of the workshop and swung open the big doors. Then he went back and crawled into the ship, swinging the thick "air-lock" door into its grooves behind him. As he climbed into the control pit, Smitty reported that the weather was just as lousy as they wanted it to be: clear, cold, and windy at high altitudes, with some low cumulus and a five-hundred-foot thick blanket of fog hugging the ground and creeping in and out of the valleys. There were several scattered thunder-showers and by morning there would be solid rain in the mountains.
Morrow switched on the gravitor units at the flight engineer's panel, then moved up and strapped himself into the co-pilot's seat. "It's your bus, Junior," he said. "Let me know when we reach my stop."
"Passengers move to the rear, please," Smitty retorted, and eased the ship cautiously out of the workshop. They swung northward and set off, flying just a few hundred feet above the mountain slopes. The moon was a cold, white gash in the black heavens, and the dark mantle of the treetops swept past below.
Unfastening his helmet, Morrow swung it back and relaxed, lighting a cigarette....
They had to use every precaution in going after Foster. In the first place, they had to consider that he might be violently opposed to their project—that, in fact, he might go straight to the authorities with it. The only safeguard against that was simply to prevent Foster from knowing where their project was located. Without that information, he would probably find it difficult to make the authorities believe him. A mere story about mechanisms that control gravity, without any basis of fact to support it, would sound rather far-fetched.
For that matter, it would have been difficult merely to visit Foster and convince him they did have such mechanisms! The only quick answer was to show him, to prove it to him. Then he would listen to them.
There was a good chance that he'd approve of their project and help them with it—otherwise, Morrow wouldn't have thought of him. And he was a man who could help them. Robert Foster was a jet engineer, employed as a flight-test analyst at an aircraft corporation's experimental plant near Sacramento. Morrow had met him, however, because Foster had written many stories for the science-fiction magazines, mostly on the galactic empire theme. They had met at a private science-fiction club in New York and spent most of a long night in a bar, along with several other writers and magazine editors, discussing subjects of vast scope and consuming beverages in vast quantity. Foster had proved himself a kindred soul of fertile imagination, if not of superior intellect, and so into the wee, small hours.
In short, Foster had impressed him as a man to be trusted when the going got rough.
Whether or not that impression had been correct, Morrow didn't know. Tonight would certainly put it to the test. They could only ask for his help, and that was all. If he refused, he refused. They couldn't use threats or coercion or any suggestion of violence—that would gain them nothing.
Fosterhadto agree! There was no one else! Without his help, they were stymied....
The weather thickened as they turned west, coming down off the slopes of the Sierras. Silvery masses of cloud drifted by in the moonlight and a thin, gray haze obscured the ground. They cruised along, their tail-jets rumbling, descending slowly to pass beneath a long row of clouds ahead. Raindrops began streaking the transparent blister which pinged at their impact; then it began a steady, ringing sound as the downpour increased. The world was turned into a gray, trickling wetness, faintly reflecting the green glow of the luminous instrument dials. The lights of a town appeared off to the left, wavering sparks in the wet gloom. Smitty swore under his breath.
They emerged from the shower to find themselves over an endless mass of cottony white, completely hiding the ground. "Now we gotta go down through that stuff!" Smitty muttered, and pushed the nose down.
The ground became dimly visible through the mist at a height of seventy feet. "Airspeed's a hundred and ten; headwind was reported at twenty miles." Smitty chanted glumly.
Morrow said nothing for a moment, knowing Smitty meant that if they were flying any faster their dim, wavering view of the ground would mean nothing. Then he started and looked up. "A hundred and ten? In a twenty-mile wind? That's ninety miles an hour!"
Smitty stared at his instruments and nodded slowly. "We're doing better than we did," he agreed. "Either that, or this wind has twisted its tail. We'll check it again."
They flew onward through the swirling, dark mist. The dark blurs of trees flashed past below, and houses, roads, and telephone lines. Dim, shadowy objects, hardly recognizable. And there were moments when the mist closed in completely, hiding everything. Morrow felt a cold sweat forming on his face. The jets made a deep, mournful rumbling sound in the ship's tail. A highway swept past below, with car headlights revealed as moving blobs of yellow in the darkness.
"This is the block," Morrow said, finally. "Swing across it and come down in that alleyway in its center. I'll tell you where to land then."
Below them were the familiar rooftops of the houses, rising darkly out of a thin ground mist. Smitty brought the ship over them, cutting the jets, and let it coast to a stop over the narrow, vague band of the alleyway. Slowly, they drifted downward.
Morrow consulted the street-map on his lap again. "Up a little further," he directed.
The jets gave a brief, rumbling sigh and they glided forward.
"Here—ground her!"
Gravel rasped against the ship's belly. They unfastened their belts and scrambled down into the ship.
"What time is it?" Smitty whispered, as Morrow swung open the door.
Morrow glanced at his wrist-watch. "Three-ten a.m.," he said half-humorously. He wondered if Foster was still waiting up for him. "Fasten your helmet down, and let's go!"
They dropped down from the ship and went over to the low, white fence behind Foster's house. Passing through the gate, they strode across the yard. The mist-shine glimmered faintly off their bodies. Their blue-tinted helmets were grotesque globes of darkness, like the heads of nightmare creatures.
Light glowed from a window in the side of the house. "Somebody's up!" Morrow observed softly.
"Do we go 'round and ring the front doorbell?" Smitty wondered. "Or do we just walk in?"
Morrow shrugged. "It won't make much difference. Let's try the back door—if it's locked, well go around."
They reached the door and he tested its knob, careful not to make any noise. It yielded readily.
They entered.
The faint light filtering down the short hallway was enough to guide them across the dark kitchen. Then they had to pass the dark doorways of what were probably two bedrooms, on either side of the hall. They reached the lighted doorway near the front, and stood looking into the living room.
Robert Foster was seated in a comfortable chair next to the television set. A single reading lamp was burning—the pipe clutched in Foster's teeth was out—and he seemed deeply engrossed in a good book.
Morrow reached up and snapped the fasteners on his helmet.
Foster lifted his gaze with the utmost casualness and studied the two figures in the doorway. He looked quite happy and contented, dressed in an old pair of slacks and loafers and a turtle-neck sweater. His dark, touselled hair showed evidence of his hand running through it—a habitual gesture of his, Morrow remembered.
Slowly, a stunned expression crept across his face.
Morrow swung his helmet back onto his gravitor tank. "Hello, Bob," he said.
Foster slipped a marker into his book, closed it, and laid it carefully aside. "Morrow?" he said. "So you finally made it! I might've known you'd be coming by way of Jupiter—but why the get-up, friend? And who's your partner?" There was just the slightest quaver in his voice.
It was almost more than Morrow had hoped for. He could play it through, now. "This is a Martian friend of mine," he said, hooking his thumb toward Smitty. "I can't stay long. Somebody might see our spaceship and get curious."
"Your—spaceship?" Foster queried falteringly.
"We landed it out in back."
The room was silent for a moment. Foster sat dumbfounded, staring at them. A flicker of a gleam began to show itself in his eyes. "Am I to understand," he said gently, "that you have landed a spaceship in my back yard?"
"No," Morrow corrected. "In the alley."
"Hmmm—it'd better be in the alley. My wife would slaughter us both if you'd trampled her gardenias." Foster fell back in his chair. He tried to relax; he even grinned, somewhat shakily. "Now what's the idea, Bill? Why'd you come tippy-toe in here like this? Out with it!"
"Take too long to explain," Morrow replied, shaking his head. "Somebody's liable to see that spaceship any minute, now." He forced a broad, innocent grin across his face. "You want to come have a look at it?"
"Ye-e-es!" Foster agreed sarcastically, rising from his chair. "I suppose Ishouldtake a look at it—"
Morrow led him out the front door and around the house. "Don't want to awaken your wife," he explained, clamping down his helmet.
"No-o-o-o!" Foster conceded. "I wouldn't advise that!" They proceeded on across the back yard, through the clinging, wet fingers of the mist.
Then Foster saw the ship.
After that, it wasn't too hard to persuade him to enter it. Then it was simple to switch on the gravitors and rise into the dark sky. Morrow had him planted in the flight engineer's seat, enthusiastically demanding explanations in full, as Smitty piloted them swiftly homeward.
Foster was sold!
They held a conference in the sawmill-workshop that lasted all the next day and well into the next night. Then Foster went home to tell his wife he'd had a hurry-up call from the aircraft plant and gone there to work on some secret research; they drove him back to Sacramento in the truck, and let him off near his house.
Then they returned to the workshop and went to work.
The following weekend, Foster drove up in his own car to see them. He climbed out of his car wearing lace-boots and hunting clothes. Reaching into the back seat, he brought out a shotgun and a stack of newspapers, then Morrow came up to greet him and they strode into the workshop.
"You fellows have really been hitting the ball!" Foster exclaimed, as he stopped and gazed at the small, needle-nosed ship sitting beside the larger ship.
Morrow nodded. They had worked night and day to construct the second, smaller ship—a little two-passenger job with sweptback fins and a canopy-covered cockpit in its sharp nose. It rested neatly on its long A-fins, poised to hurtle into the sky. Its color scheme—dark blue-black on top, light gray on its belly—stood out in sharp contrast to the solid, shimmering black of the giant ship behind it.
It had been Foster's idea. He'd pointed out to them that they needed a smaller experimental model, easier to dismantle and rebuild, for the development of their air-jet chamber.
"Have you given it a test-flight yet?" Foster asked.
"Ran it out last night," Smitty replied, coming around the two ships to meet them. He set a plumber's blowtorch on the workbench and wiped his hands on a rag. "It hit seventy miles an hour, then worked up to seventy-four after a five-hour run."
Foster shook his head in puzzlement. "That's something I just can't account for. A jet-pod ought to be just as efficient as its design, and nothing should alter its basic performance other than a change in atmospheric conditions."
"There was no atmospheric change," Morrow said. "Same altitude, same barometric pressure, same thermal conditions. I'm beginning to think the problem isn't only in the jet-pod design."
"That makes two of us!" Foster agreed. "The design I gave you should've worked better than any seventy miles an hour, if your propulsion unit develops that focus of 'false gravity' and squeezes the air out, forming a low-pressure center, as you said it did."
"We've checked that, too," Morrow said, frowning thoughtfully. "I'm beginning to think it's something to do with the gravitors' field of influence. Come over here—I want to show you something!"
He led the jet engineer over to where he and Smitty had rigged a gravitor mechanism and a sling-load of sandbags with rope attached, just as they'd used in weight-testing the gravitors. He switched on the gravitor, adjusted its setting, and let it lift the load of sandbags into the air. Then he pointed to the rope dangling down beneath it.
"See that twist in the rope, just under the sandbags?" he said. "That much of the rope is in the influence of the gravitor's field, which is cancelling out the pull of the Earth's gravity. Now then, if it can influence that three-foot length of rope, what influence might it have on the air around it—and on the slipstream of air flowing over our ships, which is supposed to enter the air-vents and be blasted out the jets for propulsion of the ships?"
"It could be scrambling our intake flow," Foster acknowledged pensively. "But would that condition alter in time?"
Morrow shook his head. "I don't think it does—or that it would unless the gravitor's batteries were almost burned out. Then the field's influence might lessen a bit. Otherwise, no."
"Then why is it that the jets' efficiency increases with time?" Foster asked. "How'd you get seventy miles an hour on the big ship, then ninety? And five hours' running built up the little ship's speed an additional four miles per hour, didn't it?"
Smitty nodded. "It gets gradually better—but not much. If we knew how it happened and what it was doing to the air-flow, maybe we could design jet-pods with the right shape to use that air-flow and get good performance."
Foster turned and peered sharply at Morrow. "Bill, doesn't that gravitor's field work by conductivity of some sort through the surrounding material?"
"Uh?" Morrow started. "Yes, it—wait! You mean the ship's plastic hull?"
"Right. And what about the polarization of that plastic?"
Morrow pursed his lips, contemplatively. "Like all materials on Earth, it's polarized—if you want to use that word—to the gravitational and magnetic fields of Earth. I see what you're driving at, though—the gravitors establish a field in which the Earth's gravity and magnetism are cancelled out, or bent back upon themselves. The mechanism of the gravitors, the hull they support, everything within their field of influence is placed on a basis of its own gravity, mass-attraction, magnetism, what-have-you."
"And that's gradually changing the polarization of those materials," Foster concluded. "And the gravitors' field, working through the material, is also affected. There's a gradual change in its influence on other surrounding matter—and on the slipstream flowing over the ship!"
"We'd need a wind-tunnel to test that, wouldn't we?" Smitty asked dejectedly.
"Yep," Foster agreed. "And wind-tunnels cost money. The only other way to test it would be to make a cross-country flight, and I wouldn't advise that."
"What about a cross-country night flight?" Morrow wondered.
Foster gave him a strange look. "You two haven't been reading the newspapers lately, have you?"
Morrow and Smitty exchanged glances of mingled surprise and guilt. "We've been rather busy out here," Morrow protested lamely.
"I suspected you were," Foster said, a trace of grim humor in his voice. He walked over to the drafting table in the corner, where he'd left his shotgun and bundle of newspapers. "Pull that thing down and come over here," he told them. "I've something to showyou, now!"
Morrow cranked the gravitor-sling down on the hand winch and Smitty shut it off; then they went over to where Foster was spreading newspapers on the drafting table, checking and circling columns of newsprint with a blue crayon pencil. Morrow stepped to his side and stared down at the papers. The words fairly leaped up to strike him in the eye.
MYSTERY SHIP NEAR SACRAMENTO
BLACK SPACESHIP SEEN
MARTIANS PREFER CALIFORNIA!
TWO CARS LEAVE H'WAY AS ROCKET SWOOPS
BLACK ROCKET SHIP; 'NOT OURS,' SAY AIR FORCE
There were more than a dozen news stories about it—not front-page, black-headlines stories, but two-column stories beginning on page two or three and continued in the newspaper center-section. None of it was spectacular enough to merit big headlines.
However, it had obviously been given a thorough coverage by the press. A railroad worker walking to work the Saturday morning of their trip to Sacramento had seen "a black, torpedo-shaped ship flying through the mist at low altitude, making a deep, rumbling noise." A police patrol car on the highway had seen it "flying low through the clouds, as if it were having mechanical difficulty of some sort." Two cars had left the highway and skidded into a ditch as both drivers saw "a black ship without wings swoop directly over" with a sound "like one long, continuous A-bomb explosion!"
Some said the ship was just a solid black shape, without lights or any noticeable features except the absence of any wings; some said "a long, blue flame" came from the tail of the ship. Some said "bright red, green, and blue lights were swarming around it" and some claimed there were "big windows in the sides, with something moving around inside."
Officials of the Air Force, both in California and in Washington, professed to have no knowledge about the ship. But one fact was added: both official groups said they were deeply interested in the reports for "reasons of security," that a thorough investigation would be made, and that radar surveillance along the West Coast would be intensified.
And one, final news story was headed: SEARCH FOR DOWNED 'SPACESHIP' FAILS. There had been strong belief, it said, that the mysterious black ship had been in trouble and was making a forced landing when it was sighted.
"There it is," Foster said with a tone of finality. "These are all the stories in the local papers. It's been played up from coast-to-coast, however—both in the newspapers and news telecasts. And the defense forces along the Coast are just waiting for you to pop out again so they can pounce on you."
"Along the Coast," Smitty echoed pensively. "It's significant that they haven't turned their attention to the interior—back as far as the Sierras, here—"
"Probably think it's some sort of new Russian reconnaissance aircraft," Morrow interjected. "They undoubtedly have a nice, little reception committee waiting out over the ocean."
Smitty nodded. "Any cross-country we plan to do had best be plotted due east, across the desert."
"There's the atomic project area, that way," Foster protested. "They certainly must have increased their air defenses around that."
"At low altitude, we can get around it," Smitty said.
Foster's features went slack. "Look here! You're not seriously thinking of—"
"If we had a wind-tunnel, no!" Smitty retorted wryly. "We could stick the little ship in it, let it run for a few days, watch the hull polarize itself to the gravitors' field, and note how the air-flow around the ship was affected. Then we could rip out the jet chamber and design a new one that'd work in the affected air-flow."
"Ifwe had a wind-tunnel," Morrow emphasized.
"Right!" Smitty turned back toward the ships. "So," he concluded, "we take the big ship! We head out over the desert and keep going, watching how the ship performs and what the air-flow does to her. We'll have to install a few barometric pressure-point indicators around her hull—"
"But we'd have to fly several days steady to get that hull completely polarized," Morrow said. "We can't just restrict ourselves to night flying."
Smitty winced. Then he rubbed his chin, scowling. "If we have to, Bill, we can go east to Utah, then south through Arizona to Mexico, then east again—flying across the Border at night, without lights, won't be too much trouble; and once in Mexico we won't have to worry about radar. We can go out over the Gulf of Mexico, if we want to, and then turn north and fly up the Mississippi and Ohio valleys as far as Pennsylvania. There's a lot of brush country in the neighboring mountain areas—there'd be little danger of getting seen through there. So long as we don't have to land anywhere, we're safe!"
"In other words, it'd be a cross-country endurance flight," Morrow surmised.
"But suppose the ship fails on you?" Foster demanded tersely. "Suppose you're forced down?"
"We're visitors from outer space!" Smitty replied, grinning.
Foster wasn't amused. "Let's not be foolish about this," he argued. "We've got something here that we can't let loose! The world isn't ready for it—"
"But we've got to have it perfected when the worldisready," Morrow said firmly. "Once the tension wears out and the world situation changes, we've got to act! If we aren't ready, the world will go right ahead and get mixed up in some other squabble. Then we'd have to wait again."
Smitty laid a hand on Foster's shoulder. "You can get a few days off from the plant, can't you?"
"What? Well, yes," Foster stammered. "Of course! But—"
They took off at noon on a cloudy winter day.
They spent the afternoon dividing their attention between the test-flight instruments and the surrounding sky. They hadn't the money to afford elaborate recording mechanisms to graph every moment of the flight onto neat tape-spools; they had to rely on the human eye, the questionably analytical human mind, and the servo-mechanism of a human hand wielding a pencil on a loose-leaf notebook. And they constantly expected to see a razor-winged jet fighter hurtling down from the stratosphere above them, its cannon sparkling the bright flame-color of death.
They didn't talk much that afternoon.
They took turns at the controls and eating until each had consumed his dinner, then gathered tensely in the control pit as the ship bored rumblingly into the black night. Ahead of them was the Mexican Border. Below them and around them, almost scraping the ship's belly, as low as they were, was the jumbled, boulder-strewn Arizona desert bathed in frosty white moonlight. Above were the cold, twinkling stars, the black heavens—and who could tell what radar-equipped night fighter poised above them, ready to peel off and plummet downward, guns blazing—
Then the Border was behind them. They took turns at the controls and instruments again, catching a few winks of sleep between turns. Morning dawned, and they approached the Gulf of Mexico.
Morrow checked their supplies—food and water for the trip, parts and materials stowed in the spacious cargo deck for repairs on the ship if necessary—and they took turns at breakfast. Then he and Foster sat down to an argument about the scientific implications of the gravitors. Foster was of the opinion that Einstein's theory no longer was valid, that Milne's work came closer to the truth but was still vague. Morrow thought differently, and they argued together amicably.
Noon passed, and they were over the green expanse of the Gulf. Smitty called their attention to the short-wave radio. The newscasts were quite interesting.
A professional hunter in Nevada, hired to exterminate a mountain lion which had been slaughtering a rancher's cattle, was surprised when a ship that looked "like a big, black whale" thundered over his head and plunged down behind a nearby ridge. The hunter rode hastily around the ridge, expecting to find the wreck, but the ship had vanished completely "as if the ground up and swallered it!"
A Greyhound bus proceeding across Arizona nearly swerved off the road when "a long, black torpedo at least a hundred feet long" came across the sky "so fast the air thunder-clapped behind it" and left "a trail of blue fire" behind it. Passengers on the bus verified the driver's story, with some minor variations.
Two farmers standing in a field in northern Nebraska saw a flight of six "fish-shaped" objects go over, each having a shadow "big as a barn" on the snow.
A noted banker in Chicago created an uproar when he reported seeing "a giant, black shape" rise from the waters of Lake Michigan as he was driving home in the afternoon.
An amateur astronomer in Alabama reported sighting a "strange ship" rising upward from the Earth's atmosphere "on a pillar of rocket fire." The ship had mysteriously disappeared "as soon as it left the atmosphere," the middle-aged hobbyist stated.
A Swedish Air Force jet-pilot claimed he had sighted, given chase, fired at, and seen his tracers bounce harmlessly off a "black, fish-like craft" flying at 40,000 feet above the Baltic Sea.
The news commentators added, in significant tones, that no airline pilots had yet reported seeing such craft. One added somewhat caustically that due to previous experiences the pilots probably wouldn't report anything to the authorities even if they did see anything, since the authorities persisted in treating such reports and the pilots who made them with painful ridicule; the commentator then launched into a condemnation of the current Administration.
"It would seem," Smitty observed from all this, "that we are quite famous!"
"'Notorious' is the word, I believe," Foster countered drily. "If this keeps up, some congressman is likely to introduce a bill providing that the government produce some Martians with black spaceships. The voters will demand it."
"It's good disguise for us, anyway," Morrow mused.
"Uh huh!" Foster grunted in reproof. "Unless we're found out, that is. If the public discovers that we've hoodwinked 'em and there aren't any Martian immigrants at all, they'll probably howl for our blood! I think this is going to develop into a scare-issue, Bill. I'm afraid people will want it, as an excuse to work off some of their nervous tension."
"Fine!" Smitty said grimly. "If anybody's trying to catch us, a general scare-issue will have 'em looking all over the place. We're already supposed to be in Nebraska, in Lake Michigan, in the Baltic Sea, and somewhere out in space!"
"Invisible, too!" Morrow laughed.
They passed over Louisiana in the early morning and proceeded northward up the Mississippi valley. Indicated air-speed was two hundred and thirty-eight miles per hour. Dawn was blanketed in a pouring rain. They turned off up the Ohio valley and reached the Allegheny Plateau in West Virginia, flying by instruments, topographical maps, and radio omni-range navigation.
And once they almost blundered straight into a big, six-engined commercial stratoliner. The stratoliner pulled up almost at the last minute.
By mid-afternoon, they were approaching Pennsylvania. The drizzling rain had changed to snow and sleet. Then they were forced down. The ship's air-speed fell off with an alarming suddenness. Then the entire tail structure took on a heavy load of ice.
They settled tail-down into a clearing on a densely wooded slope. The ship wallowed deep into the soft, slushy snow.
The three men got together over the table in the forward lounge. Foster kept running his hands through his hair, nervously. "We're stuck," he said. "We're stuck here for the winter unless we can rebuild the tail assembly. That jet chamber has to be changed."
It was obvious, after they had diagrammed the readings from their various flight-test instruments. The ship's hull had become completely polarized to the gravitors' field; the field influenced the air flowing over the hull, so much so that a simple air-scoop couldn't pick up air to blow through the propulsion unit and out the tail-jets. The air intake had to be designed to work on the disturbed air-flow.
"It's a little like those 'space-warps' in science-fiction yarns," Foster explained. "There's a warp of the gravitational and magnetic fields around the ship. The air-flow entering that warp bends and twists to follow it."
"We ought to redesign the entire hull to comply with that warped air-flow," Smitty suggested absently.
"The hull doesn't matter so much," Foster contradicted. "We could design it in any shape, though a sharp nose and thin guide-fins are still effective. You just happened to hit the right answer when you placed the control-surfaces forward on the nose of the ship."
"Talking isn't going to get us out of here," Morrow remarked grimly. "Let's get to work on that tail assembly."
"I got news for you!" Smitty muttered. "If we rebuild the tail with our power-tools, it'll use up the juice in our batteries. We won't have enough to get home."
"We must get our batteries recharged, then," Morrow said. "Will we have enough juice left to get out of here when we're finished?"
Smitty nodded. "And then we'll be up a creek. Where do we get our batteries recharged?"
"Couldn't one of us venture into a town around here and buy a few batteries?" Foster suggested. "Without wearing our Martian costumes, of course."
"Our Martian costumes as you call 'em are at least warm!" Smitty retorted. "It's a little cold to go wandering around out there in our coveralls."
"Wouldn't pay to risk it, anyway," Morrow said. "Suppose someone has seen our ship flying around here? Suppose they make a report that brings in the authorities and—"
"But who'd think a man in coveralls just stepped off a spaceship?" Foster persisted.
"Uh huh. You have a point, there. But if the authorities were investigating, they'd check railroad and truck shipments of any plastic or metal aircraft construction materials into this region, and where they were delivered. They'd check local machine shops, auto-parts shops, aviation parts dealers—andthey'd check garages! If one of us walks up to a garage, buys a battery, and walks away carrying it on his shoulder, don't you think the garage mechanic is going to remember him, what he looked like, how tall he was, what he weighed? How often does anyone without a car buy an auto battery and carry it away on his shoulder?"
"We might 'borrow' somebody's car," Smitty mused, grinning.
"We might be caught ten minutes afterward, too," Foster objected. "The police are quite efficient at catching car thieves."
"Then we need a car," Morrow concluded. "Smitty, can we lift out of here once we've rebuilt our jets?"
"We could travel a few hundred miles," Smitty conceded. "Not that it would get us anywhere."
Morrow grinned crookedly. "Would it get us to Westerton, New Jersey?"
It would. And the next night, it did.
The three men crouching in the control pit of the sleek, black ship looked red-eyed and haggard from fatigue and lack of sleep. They had stripped off their shoes and socks to let them dry near the ship's heater, and their damp, mud-stained coveralls were drying on their bodies. Foster had developed a wracking cough and his nose was running.
The air-speed indicator registered three hundred and sixty-eight miles per hour. Smitty stared at it, glumly. "Let's just hope it doesn't fade out on us again," he muttered.
The test of the ship's performance had been the whole purpose of their long, cross-country trip, Morrow thought wordlessly. They had made every preparation they could think of for the trip. Each had a special suit with helmet and gravitor-tank—and one additional feature: a one-man propulsion unit. They'd developed that in the workshop when they ran one of the suit's gravitors until its field had completely polarized the suit; then, when the suit was suspended high over a small wood fire, the smoke from the fire had risen up into the suit's gravitor field and twisted and swirled around to conform to the warp of that field. Knowing those twists and swirls, Foster had designed a small jet unit with air intake slots and jet-pipes which utilized the air-flow through the gravitor field.
Of course, there was one fault in this jet unit: it was designed to use the air-flow around a gravitor standing still. With the gravitor in motion, that air-flow was altered somewhat. But when Smitty had floated up in his suit with that little jet unit built into its tank, he had managed to fly around the sawmill yard at a good fifteen miles per hour. The air drag against his legs, since the gravitor made him weightless, was considerable—it flattened him out in horizontal flight and, by swinging his legs from one side to the other, he was quite capable of controlling the direction of his flight. The lift or descent of the gravitor sufficed for climbing or diving maneuvers. He'd looked like a human fish swimming in the sky.
