I didn't know that I had been. Then I remembered why. "Oh, Jeff -- I busted my pretty wings!"

"We'll get you more. Uh, brace yourself. I'm going to do it again."

"All right." He did.

I suppose Hardesty & Hardesty has more rhythm than Jones & Hardesty.

It really sounds better.

Sky Lift

"All torch pilots! Report to the Commodore!" The call echoed through Earth Satellite Station.

Joe Appleby flipped off the shower to listen. "You don't mean me," he said happily, "I'm on leave-but I'd better shove before you change your mind."

He dressed and hurried along a pa.s.sageway. He was in the outer ring of the Station; its slow revolution, a giant wheel in the sky, produced gravity-like force against his feet. As he reached his room the loud-speakers repeated, "All torch pilots, report to the Commodore," then added, "Lieutenant Appleby, report to the Commodore." Appleby uttered a rude monosyllable.

The Commodore's office was crowded. All present wore the torch, except a flight flight surgeon and Commodore Berrio himself, who wore the jets of a rocketship pilot. Berrio glanced up and went on talking: "-the situation. If we are to save Proserpina Station, an emergency run must be made out to Pluto. Any questions?" surgeon and Commodore Berrio himself, who wore the jets of a rocketship pilot. Berrio glanced up and went on talking: "-the situation. If we are to save Proserpina Station, an emergency run must be made out to Pluto. Any questions?"

No one spoke. Appleby wanted to, but did not wish to remind Berrio that he had been late. "Very well," Berrio went on. "Gentlemen, it's a job for torch pilots. I must ask for volunteers."

Good! thought Appleby. Let the eager lads volunteer and then adjourn. He decided that he might still catch the next shuttle to Earth. The Commodore continued, "Volunteers please remain. The rest are dismissed."

Excellent, Appleby decided. Don't rush for the door, me lad. Be dignified-sneak out between two taller men.

No one left. Joe Appleby felt swindled but lacked the nerve to start the exodus. The Commodore said soberly, "Thank you, gentlemen. Will you wait in the wardroom, please?" Muttering, Appleby left with the crowd. He wanted to go out to Pluto someday-sure!-but not now, not with Earthside leave papers in his pocket.

He held a torcher's contempt for the vast distance itself. Older pilots thought of interplanetary trips with a rocket-man's bias, in terms of years-trips that a torch ship with steady acceleration covered in days. By the orbits that a rocketship must use the round trip to Jupiter takes over five years; Saturn is twice as far, Ura.n.u.s twice again, Neptune still farther. No rocketship ever attempted Pluto; a round trip would take more than ninety years. But torch ships had won a foothold even there: Proserpina Station-cryology laboratory, cosmic radiation station, parallax observatory, physics laboratory, all in one quintuple dome against the unspeakable cold.

Nearly four billion miles from Proserpina Station Appleby followed a cla.s.smate into the wardroom. "Hey, Jerry," he said, "tell me what it is I seem to have volunteered for?"

Jerry Price looked around. "Oh, it's late Joe Appleby. Okay, buy me a drink."

A radiogram had come from Proserpina, Jerry told him, reporting an epidemic: "Larkin's disease." Appleby whistled. Larkin's disease was a mutated virus, possibly of Martian origin; a victim's red-cell count fell rapidly, soon he was dead. The only treatment was ma.s.sive transfusions while the disease ran its course. "So, m'boy, somebody has to trot out to Pluto with a blood bank."

Appleby frowned. "My pappy warned me. 'Joe,' he said, 'keep your mouth shut and never volunteer.'"

Jerry grinned. "We didn't exactly volunteer."

"How long is the boost? Eighteen days or so? I've got social obligations Earthside."

"Eighteen days at one-g-but this will be higher. They are running out of blood donors."

"How high? A g-and-a-half?" g-and-a-half?" Price shook his head. "I'd guess two gravities." Price shook his head. "I'd guess two gravities."

"Two g's!"

"What's hard about that? Men have lived through a lot more."

"Sure, for a short pull-out-not for days on end. Two g's strains your heart if you stand up."

"Don't moan, they won't pick you-I'm more the hero type. While you're on leave, think of me out in those lonely wastes, a grim-jawed angel of mercy. Buy me another drink."

Appleby decided that Jerry was right; with only two pilots needed he stood a good chance of catching the next Earth shuttle. He got out his little black book and was picking phone numbers when a messenger arrived. "Lieutenant Appleby, sir?" Joe admitted it.

"The-Commodore's-compliments-and-will-you-report-at-once-sir?"

"On my way." Joe caught Jerry's eye. "Who is what type?"

Jerry said, "Shall I take care of your social obligations?"

"Not likely!"

"I was afraid not. Good luck, boy."

With Commodore Berrio was the flight surgeon and an older lieutenant. Berrio said, "Sit down, Appleby. You know Lieutenant Kleuger? He's your skipper. You will be co-pilot."

"Very good, sir."

"Appleby, Mr. Kleuger is the most experienced torch pilot available. You were picked because medical records show you have exceptional tolerance for acceleration. This is a high-boost trip."'

"How high, sir?"

Berrio hesitated. "Three and one-half gravities." Three and a half g's! That wasn't a boost-that was a pullout. Joe heard the surgeon protest, "I'm sorry, sir, but three gravities is all I can approve."

Berrio frowned. "Legally, it's up to the captain. But three hundred lives depend on it."

Kleuger said, "Doctor, let's see that curve." The surgeon slid a paper across the desk; Kleuger moved it so that Joe could see it. "Here's the scoop, Appleby-"

A curve started high, dropped very slowly, made a sudden "knee" and dropped rapidly. The surgeon put his finger on the "knee." "Here," he said soberly, "is where the donors are suffering from loss of blood as much as the patients. After that it's hopeless, without a new source of blood."

"How did you get this curve?" Joe asked.

"It's the empirical equation of Larkin's disease applied to two hundred eighty-nine people."

Appleby noted vertical lines each marked with an acceleration and a time. Far to the right was one marked: "1 g- 18 days" That was the standard trip; it would arrive after the epidemic had burned out. Two gravities cut it to twelve days seventeen hours; even so, half the colony would be dead. Three g's was better but still bad. He could see why the Commodore wanted them to risk three-and-a-half kicks; that line touched the "knee," at nine days fifteen hours. That way they could save almost everybody, but, oh, brother!

The time advantage dropped off by inverse squares. Eighteen days required one gravity, so nine days took four, 'while four-and-a-half days required a fantastic sixteen gravities. But someone had drawn a line at "16 g-4.5 days." "Hey! This plot must be for a robot-torch-that's the ticket! Is there one available?"

Berrio said gently, "Yes. But what are its chances?"

Joe shut up. Even between the inner planets robots often went astray. In four-billion-odd miles the chance that one could hit close enough to be caught by radio control was slim. "We'll try," Berrio promised. "If it succeeds, I'll call you at once." He looked at Kleuger. "Captain, time is short. I must have your decision."

Kleuger turned to the surgeon. "Doctor, why not another half gravity? I recall a report on a chimpanzee who was centrifuged at high g for an amazingly long time."

"A chimpanzee is not a man."

Joe blurted out, "How much did this chimp stand, Surgeon?"

"Three and a quarter gravities for twenty-seven days."

"He did? did? What shape was he in when the test ended?" What shape was he in when the test ended?"

"He wasn't," the doctor grunted.

Kleuger looked at the graph, glanced at Joe, then said to the Commodore, "The boost will be at three and one-half gravities, sir."

Berrio merely said, "Very well, sir. Hurry over to sick bay. You haven't much time."

Forty-seven minutes later they were being packed into the scout torchship Salamander. Salamander. She was in orbit close by; Joe, Kleuger, and their handlers came by tube linking the hub of the Station to her airlock Joe was weak and dopy from a thorough washing-out plus a dozen treatments and injections. A good thing, he thought, that light-off would be automatic. She was in orbit close by; Joe, Kleuger, and their handlers came by tube linking the hub of the Station to her airlock Joe was weak and dopy from a thorough washing-out plus a dozen treatments and injections. A good thing, he thought, that light-off would be automatic.

The ship was built for high boost; controls were over the pilots' tanks, where they could be fingered without lifting a hand. The flight surgeon and an a.s.sistant fitted Kleuger into one tank while two medical technicians arranged Joe in his. One of them asked, "Underwear smooth? No wrinkles?"

"I guess."

"I'll check." He did so, then arranged fittings necessary to a man who must remain in one position for days. "The nipple left of your mouth is water; the two on your right are glucose and bouillon."

"No solids?"

The surgeon turned in the air and answered, "You don't need any, you won't want any, and you mustn't have any. And be careful in swallowing."

"I've boosted before."

"Sure, sure. But be careful."

Each tank was like an oversized bathtub filled with a liquid denser than water. The top was covered by a rubbery sheet, gasketed at the edges; during boost each man would float with the sheet conforming to his body. The Salamander Salamander being still in free orbit, everything was weightless and the sheet now served to keep the fluid from floating out. The attendants centered Appleby against the sheet and fastened him with sticky tape, then placed his own acceleration collar, tailored to him, behind his head. The surgeon came over and inspected. "You okay?" being still in free orbit, everything was weightless and the sheet now served to keep the fluid from floating out. The attendants centered Appleby against the sheet and fastened him with sticky tape, then placed his own acceleration collar, tailored to him, behind his head. The surgeon came over and inspected. "You okay?"

"Sure."

"Mind that swallowing." He added, "Okay, Captain. Permission to leave your ship, sir?"

"Certainly. Thank you, Surgeon."

"Good luck." He left with the technicians.

The room had no ports and needed none. The area in front of Joe's face was filled with screens, instruments, radar, and data displays; near his forehead was his eyepiece for the coelostat. A light blinked green as the pa.s.senger tube broke its anchors; Kleuger caught Joe's eye in a mirror mounted opposite them. "Report, Mister."

"Minus seven' minutes oh four. Tracking. Torch warm and idle. Green for light-off."

"Stand by while I check orientation." Kleuger's eyes disappeared into his coelostat eyepiece. Presently he said, "Check me, Joe."

"Aye aye, sir." Joe twisted a k.n.o.b and his eyepiece swung down. He found three star images brought together perfectly in the cross hairs. "Couldn't be better, Skipper."

"Ask for clearance."

"Salamander to Control-clearance requested to Proserpina. Automatic light-off on tape. All green."

"Control to Salamander. You are cleared. Good luck!"

"Cleared, Skipper. Minus three. Double oh!" Double oh!" Joe thought morosely that he should be half way to Earth now. Why the h.e.l.l did the military always get stuck with these succor-&-rescue jobs? Joe thought morosely that he should be half way to Earth now. Why the h.e.l.l did the military always get stuck with these succor-&-rescue jobs?

When the counter flashed the last thirty seconds he forgot his foregone leave. The l.u.s.t to travel possessed him. To go, no matter where, anywhere go! He smiled as the torch lit off.

Then weight hit him.

At three and one-half gravities he weighed six hundred and thirty pounds. It felt as if a load of sand had landed on him, squeezing his chest, making him helpless, forcing his head against his collar. He strove to relax, to let the supporting liquid hold him together. It was all right to tighten up for a pull-out, but for a long boost one must relax. He breathed shallowly and slowly; the air was pure oxygen, little lung action was needed. But he labored just to breathe. He could feel his heart struggling to pump blood grown heavy through squeezed vessels. This is awful! he admitted. I'm not sure I can take it. He had once had four g for nine minutes but he had forgotten how bad it was.

"Joe! Joe!" Joe!"

He opened his eyes and tried to shake his head. "Yes, Skipper." He looked for Kleuger in the mirror; the pilot's face was sagging and drawn, pulled into the mirthless grin of high acceleration.

"Check orientation!"

Joe let his arms float as he worked controls with leaden fingers. "Dead on, Skipper."

"Very well. Call Luna."

Earth Station was blanketed by their torch but the Moon was on their bow. Appleby called Luna tracking center and received their data on the departure plus data relayed from Earth Station. He called figures and times to Kleuger, who fed them into the computer. Joe then found that he had forgotten, while working, his unbearable weight. It felt worse than ever. His neck ached and he suspected that there was a wrinkle under his left calf. He wiggled in the tank to smooth it, but it made it worse. "How's she look, Skipper?"

"Okay. You're relieved, Joe. I'll take first watch."

"Right, Skipper." He tried to rest-as if a man could when buried under sandbags. His bones ached and the wrinkle became a nagging nuisance. The pain in his neck got worse; apparently he had wrenched it at light-off. He turned his head, but there were just two positions-bad and worse. Closing his eyes, he attempted to sleep. Ten minutes later he was wider awake than ever, his mind on three things, the lump in his neck, the irritation under his leg, and the squeezing weight.

Look, bud, he told himself, this is a long boost. Take it easy, or adrenalin exhaustion will get you. As the book says, "The ideal pilot is relaxed and unworried. Sanguine in temperament, he never borrows trouble." "The ideal pilot is relaxed and unworried. Sanguine in temperament, he never borrows trouble." Why, you chair-warming so-and-so! Were Why, you chair-warming so-and-so! Were you you at three and a half g's when you wrote that twaddle? at three and a half g's when you wrote that twaddle?

Cut it out, boy! He turned his mind to his favorite subject-girls, bless their hearts. Such self-hypnosis he had used to pa.s.s many a lonely million miles. Presently he realized wryly that his phantom harem had failed him. He could not conjure them up, so he banished them and spent his time being miserable.

He awoke in a sweat. His last dream had been a nightmare that he was headed out to Pluto at an impossibly high boost.

My G.o.d! So he was!

The pressure seemed worse. When he moved his head there was a stabbing pain down his side. He was panting and sweat was pouring off. It ran into his eyes; he tried to wipe them, found that his arm did not respond and that his fingertips were numb. He inched his arm across his body and dabbed at his eyes; it did not help.

He stared at the elapsed time dial of the integrating ancelerograph and tried to remember when he was due on watch. It took a while to understand that six and a half hours had pa.s.sed since light-off. He then realized with a jerk that it was long past time to relieve the watch. Kleuger's face in the mirror was still split in the grin of high g; his eyes were closed. "Skipper!" Joe shouted. Kleuger did not stir. Joe felt for the alarm b.u.t.ton, thought better of it. Let the poor goop sleep!

But somebody had to feed the hogs-better get the clouds out of his brain. The accelerometer showed three and a half exactly; the torch dials were all in operating range; the radiometer showed leakage less than ten percent of danger level.

The integrating accelerograph displayed elapsed time, velocity, and distance, in dead-reckoning for empty s.p.a.ce. Under these windows were three more which showed the same by the precomputed tape controlling the torch; by comparing, Joe could tell how results matched predictions. The torch had been lit off for less than seven hours, speed was nearly two million miles per hour and they were over six million miles out. A third display corrected these figures for the Sun's field, but Joe ignored this; near Earth's...o...b..t the Sun pulls only one two-thousandth of a gravity-a gnat's whisker, allowed for in precomputation. Joe merely noted that tape and D.R. agreed; he wanted an outside check.

Both Earth and Moon now being blanketed by the same cone of disturbance, he. twisted k.n.o.bs until their radar beacon beamed toward Mars and let it pulse the signal meaning "Where am I?" He did not wait for answer; Mars was eighteen minutes away by radio. He turned instead to the coelostat. The triple image had wandered slightly but the error was too small to correct.

He dictated what he had done into the log, whereupon he felt worse. His ribs hurt, each breath carried the stab of pleurisy. His hands and feet felt "pins-and-needles" from scanty circulation. He wiggled them, which produced crawling sensations and wearied him. So he held still and watched the speed soar. It increased seventy-seven miles per hour every second, more than a quarter million miles per hour every hour. For once he envied rocketship pilots; they took forever to get anywhere but they got there in comfort.
