<h4><i><b>Reaching for the Stars....</b></i></h4>
<p><i><b>Ever</b></i> since ancient man first gazed in wonder at the stars, humanity
has dreamed of traveling to outer space. Now scientists agree that
space-flight may very soon become a reality.</p>
<p><i><b>Space Platform</b></i> tells of man’s first step into outer space ... of the
difficulties and dangers of reaching for the stars. It is also an
exciting adventure. When young Joe Kenmore came to Bootstrap to install
pilot gyros in the Platform he hadn’t bargained for sabotage or murder
or love. But Joe learned that ruthless agents were determined to wreck
the project. He found that the beautiful girl he loved, and men like The
Chief, a rugged Indian steelworker, and Mike, a midget who made up for
his size by brains, would have to fight with their bare hands to make
man’s age old dream of space travel come true!</p>

<p>This acknowledgment is necessary if I am to say thanks to some experts
to whom I am indebted. There is Captain Charles Benjamin, who read over
the aviation parts of this book with pursed lips and a belligerent
attitude toward questionable statements of fact or observation. There is
Dr. John Drury Clark, whose authoritative knowledge of rocket fuels was
the basis for admitted but not extravagant extrapolation on my part.
There is the crew of a four-engined transport ship, who argued over my
manuscript and settled the argument by a zestful, full-scale
crash-landing drill—repeat, “drill”—expressly to make sure I had
described all the procedure just right. There is Willy Ley, whom I would
like to exempt from responsibility for any statement in the book, while
I acknowledge the value of personal talks with him and the pleasure
anybody who has ever read his books will recognize. And there is Dr.
Hugh S. Rice of the Hayden Planetarium, who will probably be surprised
to find that I feel I owe him gratitude. They are in great part
responsible for the factual matter in this book.</p>
<p>I think I may add, though, that I worked on it too.</p>

<h2><SPAN name="c1" id="c1"></SPAN><i>1</i></h2>
<p>There wasn’t anything underneath but clouds, and there wasn’t anything
overhead but sky. Joe Kenmore looked out the plane window past the
co-pilot’s shoulder. He stared ahead to where the sky and cloud bank
joined—it was many miles away—and tried to picture the job before him.
Back in the cargo space of the plane there were four big crates. They
contained the pilot gyros for the most important object then being built
on Earth, and it wouldn’t work properly without them. It was Joe’s job
to take that highly specialized, magnificently precise machinery to its
destination, help to install it, and see to its checking after it was
installed.</p>
<p>He felt uneasy. Of course the pilot and co-pilot—the only two other
people on the transport plane—knew their stuff. Every imaginable
precaution would be taken to make sure that a critically essential
device like the pilot gyro assembly would get safely where it belonged.
It would be—it was being—treated as if it were a crate of eggs instead
of massive metal, smoothed and polished and lapped to a precision
practically unheard of. But just the same Joe was worried. He’d seen the
pilot gyro assembly made. He’d helped on it. He knew how many times a
thousandth of an inch had been split in machining its bearings, and the
breath-weight balance of its moving parts. He’d have liked to be back in
the cargo compartment with it, but only the pilot’s cabin was
pressurized, and the ship was at eighteen thousand feet, flying west by
south.</p>
<p>He tried to get his mind off that impulse by remembering that at
eighteen thousand feet a good half of the air on Earth was underneath
him, and by hoping that the other <span class="pagenum"><SPAN name="Page_2" id="Page_2">[Pg 2]</SPAN></span>half would be as easy to rise above
when the gyros were finally in place and starting out for space. The
gyros, of course, were now on their way to be installed in the
artificial satellite to be blasted up and set in an orbit around the
Earth as the initial stage of that figurative stepladder by which men
would make their first attempt to reach the stars. Until that Space
Platform left the ground, the gyros were Joe’s responsibility.</p>
<p>The plane’s co-pilot leaned back in his chair and stretched luxuriously.
He loosened his safety belt and got up. He stepped carefully past the
column between the right- and left-hand pilot seats. That column
contained a fraction of the innumerable dials and controls the pilots of
a modern multi-engine plane have to watch and handle. The co-pilot went
to the coffeepot and flipped a switch. Joe fidgeted again on his
improvised seat. Again he wished that he could be riding in back with
the crates. But it would be silly to insist on perching somewhere in the
freight compartment.</p>
<p>There was a steady roaring in the cabin—the motors. One’s ears got
accustomed to it, and by now the noise sounded as if it were heard
through cushions. Presently the coffeepot bubbled, unheard. The co-pilot
lighted a cigarette. Then he drew a paper cup of coffee and handed it to
the pilot. The pilot seemed negligently to contemplate some dozens of
dials, all of which were duly duplicated on the right-hand, co-pilot’s
side. The co-pilot glanced at Joe.</p>
<p>“Coffee?”</p>
<p>“Thanks,” said Joe. He took the paper cup.</p>
<p>The co-pilot said: “Everything okay with you?”</p>
<p>“I’m all right,” said Joe. He realized that the co-pilot felt talkative.
He explained: “Those crates I’m traveling with——. The family firm’s
been working on that machinery for months. It was finished with the
final grinding done practically with feather dusters. I can’t help
worrying about it. There was four months’ work in just lapping the
shafts and balancing rotors. We made a telescope mounting once, for an
observatory in South Africa, but compared to this gadget we worked on
that one blindfolded!”</p>
<p><span class="pagenum"><SPAN name="Page_3" id="Page_3">[Pg 3]</SPAN></span></p>
<p>“Pilot gyros, eh?” said the co-pilot. “That’s what the waybill said. But
if they were all right when they left the plant, they’ll be all right
when they are delivered.”</p>
<p>Joe said ruefully: “Still I’d feel better riding back there with them.”</p>
<p>“Sabotage bad at the plant?” asked the co-pilot. “Tough!”</p>
<p>“Sabotage? No. Why should there be sabotage?” demanded Joe.</p>
<p>The co-pilot said mildly: “Not quite everybody is anxious to see the
Space Platform take off. Not everybody! What on earth do you think is
the biggest problem out where they’re building it?”</p>
<p>“I wouldn’t know,” admitted Joe. “Keeping the weight down? But there is
a new rocket fuel that’s supposed to be all right for sending the
Platform up. Wasn’t that the worst problem? Getting a rocket fuel with
enough power per pound?”</p>
<p>The co-pilot sipped his coffee and made a face. It was too hot.</p>
<p>“Fella,” he said drily, “that stuff was easy! The slide-rule boys did
that. The big job in making a new moon for the Earth is keeping it from
being blown up before it can get out to space! There are a few gentlemen
who thrive on power politics. They know that once the Platform’s
floating serenely around the Earth, with a nice stock of atom-headed
guided missiles on board, power politics is finished. So they’re doing
what they can to keep the world as it’s always been—equipped with just
one moon and many armies. And they’re doing plenty, if you ask me!”</p>
<p>“I’ve heard——” began Joe.</p>
<p>“You haven’t heard the half of it,” said the co-pilot. “The Air
Transport has lost nearly as many planes and more men on this particular
airlift than it did in Korea while that was the big job. I don’t know
how many other men have been killed. But there’s a strictly local hot
war going on out where we’re headed. No holds barred! Hadn’t you heard?”</p>
<p>It sounded exaggerated. Joe said politely: “I heard there was
cloak-and-dagger stuff going on.”</p>
<p><span class="pagenum"><SPAN name="Page_4" id="Page_4">[Pg 4]</SPAN></span></p>
<p>The pilot drained his cup and handed it to the co-pilot. He said: “He
thinks you’re kidding him.” He turned back to the contemplation of the
instruments before him and the view out the transparent plastic of the
cabin windows.</p>
<p>“He does?” The co-pilot said to Joe, “You’ve got security checks around
your plant. They weren’t put there for fun. It’s a hundred times worse
where the whole Platform’s being built.”</p>
<p>“Security?” said Joe. He shrugged. “We know everybody who works at the
plant. We’ve known them all their lives. They’d get mad if we started to
get stuffy. We don’t bother.”</p>
<p>“That I’d like to see,” said the co-pilot skeptically. “No barbed wire
around the plant? No identity badges you wear when you go in? No
security officer screaming blue murder every five minutes? What do you
think all that’s for? You built these pilot gyros! You had to have that
security stuff!”</p>
<p>“But we didn’t,” insisted Joe. “Not any of it. The plant’s been in the
same village for eighty years. It started building wagons and plows, and
now it turns out machine tools and precision machinery. It’s the only
factory around, and everybody who works there went to school with
everybody else, and so did our fathers, and we know one another!”</p>
<p>The co-pilot was unconvinced. “No kidding?”</p>
<p>“No kidding,” Joe assured him. “In World War Two the only spy scare in
the village was an FBI man who came around looking for spies. The
village cop locked him up and wouldn’t believe in his credentials. They
had to send somebody from Washington to get him out of jail.”</p>
<p>The co-pilot grinned reluctantly. “I guess there are such places,” he
said enviously. “You should’ve built the Platform! It’s plenty different
on this job! We can’t even talk to a girl without security clearance for
an interview beforehand, and we can’t speak to strange men or go out
alone after dark—.”</p>
<p>The pilot grunted. The co-pilot’s tone changed. “Not quite that bad,” he
admitted, “but it’s bad! It’s really bad! We lost three planes last
week. I guess you’d call it in action against saboteurs. One flew to
pieces in mid-air. Sabotage. Carrying critical stuff. One crashed on
take-off, carrying irreplaceable <span class="pagenum"><SPAN name="Page_5" id="Page_5">[Pg 5]</SPAN></span>instruments. Somebody’d put a detonator
in a servo-motor. And one froze in its landing glide and flew smack-dab
into its landing field. They had to scrape it up. When this ship got a
major overhaul two weeks ago, we flew it with our fingers crossed for
four trips running. Seems to be all right, though. We gave it the works.
But I won’t look forward to a serene old age until the Platform’s out of
atmosphere! Not me!”</p>
<p>He went to put the pilot’s empty cup in the disposal slot.</p>
<p>The plane went on. There wasn’t anything underneath but clouds, and
there wasn’t anything overhead but sky. The clouds were a long way down,
and the sky was simply up. Joe looked down and saw a faint spot of
racing brightness with a hint of colors around it. It was the sort of
nimbus that substitutes for a shadow when a plane is high enough above
the clouds. It raced madly over the irregular upper surface of the cloud
layer. The plane flew and flew. Nothing happened at all. This was two
hours from the field from which it had taken off with the pilot gyro
cases as its last item of collected cargo. Joe remembered how grimly the
two crew members had prevented anybody from even approaching it on the
ground, except those who actually loaded the cases, and how one of the
two had watched them every second.</p>
<p>Joe fidgeted. He didn’t quite know how to take the co-pilot’s talk. The
Kenmore Precision Tool plant was owned by his family, but it wasn’t so
much a family as a civic enterprise. The young men of the village grew
up to regard fanatically fine workmanship with the casual
matter-of-factness elsewhere reserved for plowing or deep-sea fishing.
Joe’s father owned it, and some day Joe might head it, but he couldn’t
hope to keep the respect of the men in the plant unless he could handle
every tool on the place and split a thousandth at least five ways. Ten
would be better! But as long as the feeling at the plant stayed as it
was now, there’d never be a security problem there.</p>
<p>If the co-pilot was telling the truth, though—.</p>
<p>Joe found a slow burn beginning inside him. He had a <span class="pagenum"><SPAN name="Page_6" id="Page_6">[Pg 6]</SPAN></span>picture in his mind
that was practically a dream. It was of something big and bright and
ungainly swimming silently in emptiness with a field of stars behind it.
The stars were tiny pin points of light. They were unwinking and
distinct because there was no air where this thing floated. The
blackness between them was absolute because this was space itself. The
thing that floated was a moon. A man-made moon. It was an artificial
satellite of Earth. Men were now building it. Presently it would float
as Joe dreamed of it, and where the sun struck it, it would be
unbearably bright, and where there were shadows, they would be abysmally
black—except, perhaps, when earthshine from the planet below would
outline it in a ghostly fashion.</p>
<p>There would be men in the thing that floated in space. It swam in a
splendid orbit about the world that had built it. Sometimes there were
small ships that—so Joe imagined—would fight their way up to it,
panting great plumes of rocket smoke, and bringing food and fuel to its
crew. And presently one of those panting small ships would refill its
fuel tanks to the bursting point from the fuel other ships had
brought—and yet the ship would have no weight. So it would drift away
from the greater floating thing in space, and suddenly its rockets would
spout flame and fumes, and it would head triumphantly out and away from
Earth. And it would be the first vessel ever to strike out for the
stars!</p>
<p>That was the picture Joe had of the Space Platform and its meaning.
Maybe it was romantic, but men were working right now to make that
romance come true. This transport plane was flying to a small town
improbably called Bootstrap, carrying one of the most essential devices
for the Platform’s equipment. In the desert near Bootstrap there was a
gigantic construction shed. Inside that shed men were building exactly
the monstrous object that Joe pictured to himself. They were trying to
realize a dream men have dreamed for decades—the necessary space
platform that would be the dock, the wharf, the starting point from
which the first of human space explorers could start for infinity. The
idea that anybody <span class="pagenum"><SPAN name="Page_7" id="Page_7">[Pg 7]</SPAN></span>could want to halt such an undertaking made Joe
Kenmore burn.</p>
<p>The co-pilot painstakingly crushed out his cigarette. The ship flew with
more steadiness than a railroad car rolls on rails. There was the oddly
cushioned sound of the motors. It was all very matter-of-fact.</p>
<p>But Joe said angrily: “Look! Is any of what you said—well—kidding?”</p>
<p>“I wish it were, fella,” said the co-pilot. “I can talk to you about it,
but most of it’s hushed up. I tell you——”</p>
<p>“Why can you talk to me?” demanded Joe suspiciously. “What makes it all
right for you to talk to me?”</p>
<p>“You’ve got passage on this ship. That means something!”</p>
<p>“Does it?” asked Joe.</p>
<p>The pilot turned in his seat to glance at Joe.</p>
<p>“Do you think we carry passengers regularly?” he asked mildly.</p>
<p>“Why not?”</p>
<p>Pilot and co-pilot looked at each other.</p>
<p>“Tell him,” said the pilot.</p>
<p>“About five months ago,” said the co-pilot, “there was an Army colonel
wangled a ride to Bootstrap on a cargo plane. The plane took off. It
flew all right until twenty miles from Bootstrap. Then it stopped
checking. It dove straight for the Shed the Platform’s being built in.
It was shot down. When it hit, there was an explosion.” The co-pilot
shrugged. “You won’t believe me, maybe. But a week later they found the
colonel’s body back east. Somebody’d murdered him.”</p>
<p>Joe blinked.</p>
<p>“It wasn’t the colonel who rode as a passenger,” said the co-pilot. “It
was somebody else. Twenty miles from Bootstrap he’d shot the pilots and
taken the controls. That’s what they figure, anyhow. He meant to dive
into the construction Shed. Because—very, very cleverly—they’d managed
to get a bomb in the plane disguised as cargo. They got the men who’d
done that, later, but it was rather late.”</p>
<p>Joe said dubiously: “But would one bomb destroy the Shed and the
Platform?”</p>
<p><span class="pagenum"><SPAN name="Page_8" id="Page_8">[Pg 8]</SPAN></span></p>
<p>“This one would,” said the co-pilot. “It was an atom bomb. But it wasn’t
a good one. It didn’t detonate properly. It was a fizz-off.”</p>
<p>Joe saw the implications. Cranks and crackpots couldn’t get hold of the
materials for atom bombs. It took the resources of a large nation for
that. But a nation that didn’t quite dare start an open war might try to
sneak in one atom bomb to destroy the space station. Once the Platform
was launched no other nation could dream of world domination. The United
States wouldn’t go to war if the Platform was destroyed. But there could
be a strictly local hot war.</p>
<p>The pilot said sharply: “Something down below!”</p>
<p>The co-pilot fairly leaped into his right-hand seat, his safety belt
buckled in half a heartbeat.</p>
<p>“Check,” he said in a new tone. “Where?”</p>
<p>The pilot pointed.</p>
<p>“I saw something dark,” he said briefly, “where there was a deep dent in
the cloud.”</p>
<p>The co-pilot threw a switch. Within seconds a new sound entered the
cabin. <i>Beep-beep-beep-beep.</i> They were thin squeaks, spaced a full
half-second apart, that rose to inaudibility in pitch in the fraction of
a second they lasted. The co-pilot snatched a hand phone from the wall
above his head and held it to his lips.</p>
<p>“Flight two-twenty calling,” he said crisply. “Something’s got a radar
on us. We saw it. Get a fix on us and come a-running. We’re at eighteen
thousand and”—here the floor of the cabin tilted markedly—“now we’re
climbing. Get a fix on us and come a-running. Over!”</p>
<p>He took the phone from his lips and said conversationally: “Radar’s a
giveaway. This is no fly-way. You wouldn’t think he’d take that much of
a chance, would you?”</p>
<p>Joe clenched his hands. The pilot did things to the levers on the column
between the two pilots’ seats. He said curtly: “Arm the jatos.”</p>
<p>The co-pilot did something mysterious and said: “Check.”</p>
<p>All this took place in seconds. The pilot said, “I see something!” and
instantly there was swift, tense teamwork in <span class="pagenum"><SPAN name="Page_9" id="Page_9">[Pg 9]</SPAN></span>action. A call by radio,
asking for help. The plane headed up for greater clearance between it
and the clouds. The jatos made ready for firing. They were the
jet-assisted take-off rockets which on a short or rough field would
double the motors’ thrust for a matter of seconds. In straightaway
flight they should make the plane leap ahead like a scared rabbit. But
they wouldn’t last long.</p>
<p>“I don’t like this,” said the co-pilot in a flat voice. “I don’t see
what he could do——”</p>
<p>Then he stopped. Something zoomed out of a cloud. The action was
completely improbable. The thing that appeared looked absolutely
commonplace. It was a silver-winged private plane, the sort that cruises
at one hundred and seventy-five knots and can hit nearly two-fifty if
pushed. It was expensive, but not large. It came straight up out of the
cloud layer and went lazily over on its back and dived down into the
cloud layer again. It looked like somebody stunting for his own private
lunatic pleasure—the kind of crazy thing some people do, and for which
there is no possible explanation.</p>
<p>But there was an explanation for this.</p>
<p>At the very top of the loop, threads of white smoke appeared. They
should have been unnoticeable against the cloud. But for the fraction of
an instant they were silhouetted against the silver wings. And they were
not misty wisps of vapor. They were dense, sharply defined rocket
trails.</p>
<p>They shot upward, spreading out. They unreeled with incredible,
ever-increasing velocity.</p>
<p>The pilot hit something with the heel of his hand. There was a
heart-stopping delay. Then the transport leaped forward with a force to
stop one’s breath. The jatos were firing furiously, and the ship jumped.
There was a bellowing that drowned out the sound of the engines. Joe was
slammed back on the rear wall of the cabin. He struggled against the
force that pushed him tailward. He heard the pilot saying calmly: “That
plane shot rockets at us. If they’re guided we’re sunk.”</p>
<p>Then the threads of smoke became the thickness of cables, of columns!
They should have ringed the transport plane in. But the jatos had jumped
it crazily forward and were still <span class="pagenum"><SPAN name="Page_10" id="Page_10">[Pg 10]</SPAN></span>thrusting fiercely to make it go
faster than any prop-plane could. The acceleration made the muscles at
the front of Joe’s throat ache as he held his head upright against it.</p>
<p>“They’ll be proximity——”</p>
<p>Then the plane bucked. Very probably, at that moment, it was stretched
far past the limit of strain for which even its factor of safety was
designed. One rocket had let go. The others went with it. The rockets
had had proximity fuses. If they had ringed the transport ship and gone
off with it enclosed, it would now be a tumbling mass of wreckage. But
the jatos had thrown the plane out ahead of the target area. Suddenly
they cut off, and it seemed as if the ship had braked. But the pilot
dived steeply, for speed.</p>
<p>The co-pilot was saying coldly into the microphone: “He shot rockets.
Looked like Army issue three point fives with proximities. They missed.
And we’re mighty lonely!”</p>
<p>The transport tore on, both pilots grimly watching the cloud bank below.
They moved their bodies as they stared out the windows, so that by no
possibility could any part of the plane mask something that they should
see. As they searched, the co-pilot spoke evenly into the microphone at
his lips: “He wouldn’t carry more than four rockets, and he’s dumping
his racks and firing equipment now. But he might have a friend with him.
Better get here quick if you want to catch him. He’ll be the innocentest
private pilot you ever saw in no time!”</p>
<p>Then the pilot grunted. Something was streaking across the cloud
formation far, far ahead. Three things. They were jet planes, and they
seemed not so much to approach as to swell in size. They were coming at
better than five hundred knots—ten miles a minute—and the transport
was heading for them at its top speed of three hundred knots. The
transport and the flight of jets neared each other at the rate of a mile
in less than four seconds.</p>
<p>The co-pilot said crisply: “Silver Messner with red wing-tips. The
number began——” He gave the letter and first digits of the vanished
plane’s official designation, without <span class="pagenum"><SPAN name="Page_11" id="Page_11">[Pg 11]</SPAN></span>which it could not take off from
or be serviced at any flying field.</p>
<p>Joe heard an insistent, swift <i>beep-beep-beep-beep</i> which would be the
radars of the approaching jets. He could not hear any answers that might
reach the co-pilot as he talked to unseen persons who would relay his
words to the jet fighters.</p>
<p>One of them peeled off and sank into the cloud layer. The others came
on. They set up in great circles about the transport, crossing before
it, above it, around it, which gave the effect of flying around an
object not in motion at all.</p>
<p>The pilot flew on, frowning. The co-pilot said: “Yes. Sure! I’m
listening!” There was a pause. Then he said: “Check. Thanks.”</p>
<p>He hung the instrument back where it belonged, above his head and behind
him. He thoughtfully mopped his brow. He looked at Joe.</p>
<p>“Maybe,” he said mildly, “you believe me when I tell you there’s a sort
of hot war on, to keep the Platform from taking off.”</p>
<p>The pilot grunted. “Here’s the third jet coming up.”</p>
<p>It was true. The jet that had dived into the clouds came up out of the
cloud formation with somehow an air of impassive satisfaction.</p>
<p>“Did they spot the guy?”</p>
<p>“Yeah,” said the co-pilot. “He must’ve picked up my report. He didn’t
dump his radar. He stayed in the cloud bank. When the jet came for
him—spotting him with its night-fighter stuff—he tried to ram. Tried
for a collision. So the jet gave him the works. Blew him apart. Couldn’t
make him land. Maybe they’ll pick up something from the wreckage.”</p>
<p>Joe wet his lips.</p>
<p>“I—saw what happened,” he said. “He tried to smash us with rockets.
Where’d he get them? How were they smuggled in?”</p>
<p>The co-pilot shrugged. “Maybe smuggled in. Maybe stolen. They coulda
been landed from a sub anywhere on a good many thousand miles of coast.
They coulda been hauled anywhere <span class="pagenum"><SPAN name="Page_12" id="Page_12">[Pg 12]</SPAN></span>in a station wagon. The plane was a
private-type ship. Plenty of them flying around. It could’ve been bought
easily enough. All they’d need would be a farm somewhere where it could
land and they could strap on a rocket rack and put in a radar. And
they’d need information. Probably be a good lead, this business. Only
just so many people could know what was coming on this ship, and what
course it was flying, and so on. Security will have to check back from
that angle.”</p>
<p>A shadow fell upon the transport ship. A jet shot past from above it. It
waggled its wings and changed course.</p>
<p>“We’ve got to land and be checked for damage,” said the co-pilot
negligently. “These guys will circle us and lead the way—as if we
needed it!”</p>
<p>Joe subsided. He still had in his mind the glamorous and infinitely
alluring picture of the Space Platform floating grandly in its orbit,
with white-hot sunshine on it and a multitude of stars beyond. He had
been completely absorbed in that aspect of the job that dealt with the
method of construction and the technical details by which the Platform
could be made to work.</p>
<p>Now he had a side light on the sort of thing that has to be done when
anything important is achieved. Figuring out how a thing can be done is
only part of the job. Overcoming the obstacles to the apparently
commonplace steps is nine-tenths of the difficulty. It had seemed to him
that the most dramatic aspect of building the Space Platform had been
the achievement of a design that would work in space, that could be
gotten up into space, and that could be lived in under circumstances
never before experienced. Now he saw that getting the materials to the
spot where they were needed called for nearly as much brains and effort.
Screening out spies and destructionists—that would be an even greater
achievement!</p>
<p>He began to feel a tremendous respect and solicitude for the people who
were doing ordinary jobs in the building of the Platform. And he worried
about his own share more than ever.</p>
<p>Presently the transport ship sank toward the clouds. It <span class="pagenum"><SPAN name="Page_13" id="Page_13">[Pg 13]</SPAN></span>sped through
them, stone-blind from the mist. And then there was a small airfield
below, and the pilot and co-pilot began a pattern of ritualistic
conversation.</p>
<p>“Pitot and wing heaters?” asked the pilot.</p>
<p>The co-pilot put his hand successively on two controls.</p>
<p>“Off.”</p>
<p>“Spark advance?”</p>
<p>The co-pilot moved his hands.</p>
<p>“Take-off and climb?” said the co-pilot.</p>
<p>“Blowers?”</p>
<p>“Low.”</p>
<p>“Fuel selectors?”</p>
<p>The co-pilot moved his hands again to the appropriate controls,
verifying that they were as he reported them.</p>
<p>“Main on,” he said matter-of-factly, “crossfeed off.”</p>
<p>The transport plane slanted down steeply for the landing field that had
looked so small at first, but expanded remarkably as they drew near.</p>
<p>Joe found himself frowning. He began to see how really big a job it was
to get a Space Platform even ready to take off for a journey that in
theory should last forever. It was daunting to think that before a space
ship could be built and powered and equipped with machinery there had to
be such wildly irrelevant plans worked out as a proper check of controls
for the piston-engine ships that flew parts to the job. The details were
innumerable!</p>
<p>But the job was still worth doing. Joe was glad he was going to have a
share in it.</p>
