If a Z-B AS pilot wanted repairs before it would fly, Lawrence was very happy to have the procedure carried out. The spaceplane would definitely need it.
The enforced hiatus didn't sit so well with the rest of his platoon. Worst hit was Hal Grabowski, the youngest member, just past nineteen years old. Hal's flight experience was limited to one subsonic transocean flight to Australia and five short helicopter trips during the last phase of their training. He'd never been on a spaceplane, let alone experienced freefall. Spaceflight was a novelty he was hungry for, prowling around the lounge in search of some sign that they could embark. A sure giveaway that he'd never seen active service before, either. The ancient armed forces maxim—never volunteer—had streaked over Hal's head at near-orbital altitude.
"It's been three hours!" the kid complained. "Fuck this. Hey, Corp, if they don't fix it, will they give us another spaceplane soon?"
"Yeah, I expect so," Corporal Amersy muttered. He didn't even glance up from the screen on his media player card.
Hal's arms flapped about in disgust He stomped off to annoy someone else. Amersy looked up, watching the kid's back, then turned and smiled at Lawrence. The two of them shook their heads in unison. Amersy was a good ten years older than Lawrence, though his thinning hair was the only outward sign of aging. He was very careful to keep in shape, spending hours each week in the base gym. Good physical condition was a non-negotiable requirement Z-B placed on all its strategic security division squaddies. Amersy was never going to rise above corporal; he had neither the stake-holding nor the connections. It didn't bother him; the position meant he could take good care of his family, so he worked hard at maintaining it. That worked to Lawrence's advantage; Amersy was the most reliable corporal in the Third Fleet.
Only his face betrayed the time he'd devoted to the front line of Z-B's asset-realization policy. A wide patch of skin at the rear of his left cheek was slightly chewed up where a Molotov cocktail had burned through his helmet fifteen years earlier in the Shuna campaign, before Skin reached anything like its current level of ability. Even that shouldn't have been too visible, not with the dark ebony color of Amersy's skin. But that day the Third Fleet field hospital had been inundated with casualties; at the end of a twenty-two-hour shift, the trauma doctor was too fast applying dermal regeneration virals. They'd done the job they were designed for, infiltrating the corium layer to implant new genetic material that would build his epidermal layer back over deep char ridges. Unfortunately the genes that the virals carried were tailored for a Caucasian. Half of Amersy's cheek was white, resembling some kind of flat tumor.
Amersy allowed rookie squaddies to have one joke about it. Hal, naturally, had made a second. The kid was taller even than Lawrence, topping out over two meters, with muscles that could match a Skin suit's strength. It didn't make any difference; he'd limped for a week after landing badly. The kid had shown the corporal plenty of respect since then; it was about the only lesson he had ever learned properly in the whole nine weeks since he'd joined the platoon.
"Are there going to be stewardesses?" Hal asked Edmond Orlov. "You know, some decent-looking pussy."
"It's a fucking military flight, you dipshit," Edmond sneered at him. "Officers and management get freefall blow jobs. You get to fuck Karl."
Karl Sheahan lifted his head, blinking his eyes open. Tiny colored silhouettes shivering over his optronic membranes shrank to nothing. He gave the pair of them the finger.
"What about the starship?" Hal persisted. "Any chicks in the crew?"
"I haven't got a fucking clue. And even if they were all female, it wouldn't make any goddamn difference to you. Crew only ever get the best, that means their fucking coffee machine is smarter and more attractive than you."
"Aww man, that is such a waste. I mean, how many times does a guy have this kind of opportunity? The way I figure, I'll see six, maybe seven campaigns. That'll give me a total of fourteen spaceflights. I don't wanna waste none; that's criminal."
"Waste them how?"
"Boomeranging the padding, man. The big freefall freefor-all. A midair rodeo." He clenched his fists and held them up, pleading. "I wanna have sex in zero-gee, man! Every unnatural position you're not built for. Holy shit. I get hard just thinking about it."
"Shut up, you arrested pervert. There's no such thing. The whole idea's a myth dreamed up by corporate publicity back when they started flying orbital sight-seeing tours. Get it? You even twist your head around fast in freefall and you throw up. You start tumbling around the way you're thinking of, and every orifice lets fly. And I mean every. Now forget about it and give the rest of us a break."
Hal backed off, looking wounded. Edmond was the closest he had to a genuine buddy in the platoon. The two of them had broken base curfew enough nights to go cruising the Cairns Strip together. .
Lawrence waited silently, hoping the kid would finally shut up. There were ten other platoons waiting in the lounge with them, all of them hyped with the prospect of the flight It wouldn't take much to start a fight. He didn't want to start ordering the kid about before the mission had even taken off. None of the others were such a pain, but then they were older, half of them had families, too, which acted like a damping rod on wilder aspects of their behavior. And all of them had seen duty together.
Hal walked over to one of the big picture windows, pressing his face against it to look eagerly out at the huge space-planes that were managing to take off. He took a swig from a Coke can.
"Hal, stop drinking now," Amersy said. "You don't want any fluid in your stomach when we go into orbit. You'll throw up even if you don't twist your head."
Hal glared at the can. He dropped it and kicked it in the direction of the nearest wastebasket. There was no other form of protest.
The kid would do all right, Lawrence decided. He just needed guiding through the first few crowd encounters and he'd start to learn caution. Pity he didn't have a steady girlfriend; that was always a calming influence. But at nineteen he was only interested in screwing as many girls as he could impress by his muscles and his credit card.
Four and a half hours into the wait, and the departure sheet screen changed their flight status to boarding. Hal let out a loud whoop and snatched up his small bag. The rest of Platoon 435NK9 lumbered up out of their chairs and made their way over to the designated gate. Their spaceplane was rolling slowly into the departure bay as they assembled at the clearance desk.
The Xianti 5005h3 spaceplane was a well-proven commercial ground-to-orbit vehicle; the Beijing Astronautics Company had first flown the original 5005a mark in 2290. Since then there had been over forty variants produced as the manufacturer gradually expanded capacity and smoothed out early bugs. The 5005h3 was a stretched delta planform 120 meters long, with a wingspan of a hundred meters. Eighty percent of its volume was taken up by fuel tanks. Its carbon-lithium composite fuselage had a broad center section with graceful curves blending it cleanly into the wing section, a softness in sharp contrast to the knife-blade leading edges. A third of the way down the belly was a single oval scoop intake with an airspike protruding several meters from the rim.
Several gantry service arms rose out of the departure bay's concrete, carrying pipes and utility cables that were plugged into sockets along the Xianti's belly. Technicians in silver fire suits were walking about underneath, inspecting the huge wheel bogies and keeping an eye on the fueling process. A tall girder tower at one side of the bay had clean white vapor flowing silently out of a nozzle on the top, dissipating fast in the warm breeze. That was the only sign that the spaceplane used cryogenic fuel. Its fuselage remained remarkably free from condensation as the on-board tanks were chilled down and filled.
A pair of Z-B spaceflight division staff stood behind the clearance desk, handing out protective black plastic helmets, similar to the kind cyclists used. They made sure everyone put theirs on before embarking. At the end of the sealed walkway a small grimy window looked back along the huge vehicle. That was the las
t sight Lawrence was given of the spaceplane—a vast expanse of silver-blue wing surface, its size the only indication of the raw power to be unleashed in the flight. As he walked past he felt that familiar small twist of envy, wishing that he were the pilot who hauled this superb monster up through the atmosphere into space and freedom. Except, as all the years since Amethi had shown him, it wasn't true freedom. At some time, you always had to come back down to earth. That wish was the wonderful deceit that had so far cost him twenty years of his life.
The Xianti's passenger cabin was remarkably similar to that of a standard aircraft. Same worn-down blue-gray carpet, not just on the floor but the walls and ceiling, too; pale gray plastic lockers above the seats, harsh lighting, small vent nozzles hissing out dry air a couple of degrees too cool for real comfort. There was plenty of headroom, though, and the chairs had deep jelfoam padding as well as being spaced well apart. All that was missing were windows.
Lawrence made sure the platoon stowed their bags and strapped themselves in securely before he fastened his own buckles. Seatback screens ran through a few brief safety procedures. Lawrence ignored them. Not that he was blasй about spaceflight, more like pragmatic. At takeoff, the spaceplane carried nearly five hundred metric tons of cryogenic hydrogen. No major emergency was survivable.
The Xianti taxied to the end of the runway, and the human pilot cleared the AS for launch. Four Rolls-Royce RBS8200 turbojets throttled up, producing seventy-five tons of thrust.
They began to race down the runway. Seatback screens showed Lawrence the scenery flashing by; the green blur transferred smoothly into a pale blue as they lifted from the tarmac. Then the huge bogies retracted with a noise more like sections of fuselage tearing off. The blue slowly began to darken.
With full afterburn the turbojets pushed the Xianti up to Mach 2.6 somewhere above the Willis Islands. The scramjet ignited then, liquid hydrogen vaporizing in carefully designed supersonic plume patterns within the hot compressed airflow before combusting in long, lean azure flames. It produced 250 tons of thrust, shaking the cabin with a gullet-rattling roar as it pushed the spaceplane ever higher through the stratosphere.
Lawrence clamped his teeth together as the G-force crept upward and the scramjet's fierce vibration blurred his vision. The pressure on his lungs increased toward the verge of pain. He tried to concentrate on breathing regularly—not easy through the building anxiety. The enormity of their power-dive up into orbit made him understand just how insignificant he was in relation to the energies driving them, how hopelessly dependent they were that the obsolete design programs had been used properly fifty years ago, calculating theoretical parameters of aerothermaldynamic flow; that everything was going to work and keep on working under obscene stresses.
Stars began to appear in the seatback screen as the velvet blue panorama drained away into midnight black. The AS pilot began to throttle back the scramjet as they reached Mach 20. They were at the top of the atmosphere now, still soaring upward from the impetus of the burn. Even at that speed, the oxygen density was falling below sustainable combustion levels. Two small rocket motors in the tail fired up, producing a mere fifteen tons of thrust each, which gently eased the spaceplane up to orbital velocity. They created the illusion that the spaceplane was standing vertical on a low-gravity moon. Lawrence's chair creaked as its struts adjusted to the new loading. At least the pounding roar was over.
The glaring blue-white crescent of Earth slid into the bottom of the seatback screen as the rockets cut off, taking with them the last percentage of G-force. Every nerve in Lawrence's body was screaming at him that they were now falling back to the ground, ninety kilometers below. He took some quick shallow breaths, trying to convince himself that the sensation was perfectly natural. It didn't work particularly well, but he was soon distracted by the sounds of worse suffering from his fellow passengers.
For forty minutes the Xianti glided along its course, passing over Central America and out across the Atlantic. Seat-back screens flashed a quick warning, and the small rockets fired again, circularizing their orbit at four hundred kilometers' altitude. After that Lawrence heard a whole new series of mechanical whines and thuds. The spaceplane was opening small hatches on its upper fuselage, extending silver radiator panels to shed heat generated by the life support systems and power cells. Its radar began tracking the Moray. The orbital transfer ship was twenty kilometers ahead, in a slightly higher orbit. Reaction control thrusters adjusted their trajectory in minute increments, closing the gap.
Lawrence watched the screen as the Moray grew from a silver speck to a fully defined ship. It was three hundred meters long, and about as basic as any space vehicle could get. Habitation cabins were five cylinders clustered together, thirty-five meters long, eight wide. They'd been sprayed with a half-meter layer of carbon-based foam, which was supposed to act as a thermal shield as well as providing protection from cosmic radiation. Lawrence had checked the solarwatch bulletin before they took off. Sunspot activity was moderate with several new disturbances forming, one of them quite large. He hadn't told the rest of the platoon, but he was quietly relieved the transfer would take only thirty hours. He didn't trust the foam to protect him from anything serious. Its original white coloring had darkened to pewter gray as the years of vacuum exposure boiled the surface, and even with the spaceplane camera's poor resolution he could see pocks and scars from micrometeorite impacts.
Behind the cylinders was a life support deck, a clump of tanks, filter mechanisms and heat exchangers. A broad collar of silver heat-radiator panels stretched out from the circumference, each segment angled to keep the flat surface away from direct sunlight.
Next was the freight section, a fat trellis of girders sprouting a multitude of loading pins, clamps and environmental maintenance sockets. For the last three weeks, the Cairns base spaceplanes had been boosting cargo pods up to the Moray and its sister ships. They'd been ferrying them up to Centralis at the Lagrange four orbital point where the star-ships waited, then returning to low Earth orbit for more. Even now there wasn't a single unoccupied clamp. They contained the helicopters, jeeps, equipment, armaments and supplies for the Third Fleet's ground forces; everything they'd need to mount a successful mission.
The final section of the ship was given over to propulsion. It housed two small tokamak fusion reactors and their associated support machinery, a tightly packed three-dimensional maze of tanks, cryostats, superconductor magnets, plasma inductors, pumps, electron injectors and high-voltage cabling. The fifteen heat radiator panels necessary to cope with the system were over a hundred meters long, sticking out from the ship like giant propeller blades. The tokamaks fed their power into a high-thrust ion drive, eight grid nozzles buried in a simple box structure that was fixed to the base of the ship almost as an afterthought.
Moray's length drifted past the camera as the Xianti gently maneuvered itself to the docking tower at the front. Reaction control engines drummed incessantly, turning the spaceplane along its axis as it was nudged ever closer. Then the airlock rings were aligned, snapping together with a clang.
Lawrence took a look around the cabin. Several squaddies had thrown up, and the larger air grilles along the ceiling and floor were splattered with the residue. Checking his own platoon he could see several of them showing signs of queasiness. Hal, of course, had an expression of utter delight on his face. Zero-G didn't seem to have any adverse effect on him at all. Typical, Lawrence thought; he could already feel his own face puffing up as fluids began to pool in his flesh.
The airlock hatch swung open, and the cabin PA hissed on. "Okay, we're docked and secure," the human pilot said. "You can egress the transorbital now."
Lawrence waited until the platoon sitting in front of him had gone through the airlock before releasing his own straps. "Remember to move slowly," he reminded his people. "You've got a lot of inertia to contend with."
They did as they were told, unbuckling the restraints and gingerly easing themselves out of t
he deep seats. It had been over eighteen months since any of them had been in freefall, and it showed—sluggish movements suddenly becoming wild spins. Desperate grabs. Elbows thudding painfully into lockers and seat corners. Lawrence Velcroed his bag to his chest, and used the inset handles along the ceiling to make his way forward. In his mind, he tried to match the process with climbing a ladder. A good grounding psychology: always try for a solid visual reference. Except here his legs wanted to slide out to the side and twist him around. His abdominal muscles tensed, trying to keep his body straight. Someone knocked into his feet. When he glanced around to glare, Odel Cureton was grimacing in apology, his own body levering around his tenuous handhold, putting a lot of strain on his wrists.
