Peter Hamilton - Judas Unchained

As they drew up to it, Mellanie pressed harder against the glass, keen to see the planes they’d be flying on. Four of Half Way’s nine HA-1 Carbon Goose flying boats were resting on the rock just above the sea. She stared in awe at the massive silver-white fuselages gleaming under the red sun as their true size sank in.

When the Commonwealth Council was assembling the financial package necessary for CST to establish a wormhole link to Far Away, its members had been actively concerned about the possibility of anything hostile finding its way back to the Commonwealth. Given the nature of the flare that had been detected on Damaran, they had the reasonable enough worry that the aliens who triggered it might be antagonistic. The safeguard they insisted on was simple enough. The two respective wormhole gateway stations on Half Way must be separated by a considerable distance so that the route to Boongate could be severed in the event anything wicked did force its way off Far Away. After a full survey of Half Way, they went on to build the stations, Shackleton and Port Evergreen, on islands over ten thousand kilometers apart.

It was the Halgarths, the political instigators of the whole Far Away project, who provided the link between the islands. Some quirk of dynastic pride made Heather Antonia Halgarth decide on the largest aircraft ever built. The components were all constructed on EdenBurg and shipped in through Boongate to be assembled in Shackleton’s hangars. Made out of a carbotanium composite structure, each Carbon Goose measured a hundred twenty-two meters long, with a corresponding wingspan of a hundred ten meters. They had six engines, air-cooled fission micropile ducted turbines producing thirty-two thousand kilograms of thrust each, enough to give the plane a cruising speed of point nine mach. Range was effectively unlimited; the micropiles needed replacing only every twenty-five years.

The steward led them down from the train, and started shepherding them toward the Carbon Goose they were going to use. Behind them, a couple of CST staff emerged from a hut and began supervising the cargo removal. Loaderbots lifted up crates and transferred them to a small fleet of flatbed wagons that would drive them over to the plane.

Mellanie felt her suit stiffen and inflate as the airlock’s outer door opened. Valves soon equalized the pressure. Half Way’s atmosphere wasn’t hugely toxic—the majority of the gas was the kind of nitrogen oxygen mix found on H-congruous worlds—but it also contained unacceptably high levels of carbon dioxide and argon, which made filters or a rebreather essential. Equatorial temperature in the daytime fluctuated between minus ten and minus fifteen Celsius. Again, not immediately lethal, but heated suits were indispensable.

She walked a few paces away from the bottom of the steps and tilted her head back. Another bright flash erupted in the sky. It came from a tiny radiant point close to the gibbous bulk of the M-class star.

“Is that it?” she asked Dudley.

He was gawping up at the sky, for once looking quite serene. “Yes. That’s the companion. I was hoping you could see the plasma tide, but it doesn’t seem to be substantial enough for naked eye observation.”

“You mean the sun’s atmosphere?”

“Not the corona itself, no, though that does undergo constant tidal distortion. The neutron star is orbiting close enough to the sun to attract most of its solar wind. The plasma gets tugged out into gigantic streamers across the gulf and then spirals down to the neutron star. All the flashes you see are impact waves.”

As he was talking the neutron star flared again. Mellanie had to blink and look away, the light was so intense. It left a dense purple afterimage in her vision.

“Is that radioactive?”

“It emits radiation, Mellanie, it’s not radioactive. The two are quite separate.”

“All right,” she said in faint annoyance. “Is it dangerous?”

“There’s quite a heavy gamma and X-ray burst each time, yes. But Half Way’s atmosphere will protect us from the worst. You perhaps wouldn’t want to stay out here for a week, though.”

“I’ll try to remember.” She marched off toward the waiting flying boat, irritated by the way he’d switched into his lecturer persona.

The Carbon Goose was standing on its triple undercarriage, with aluminum air stairs extended from a forward airlock hatch. A long cargo hold was open amidships, with loaderbots transferring crates on board. As Mellanie drew closer she got a clear view of the sea behind the vast aircraft as it rippled against the inlet’s natural ramp of rock. It wasn’t perfectly still after all; the surface undulated slowly as it was stirred by the gentle currents of air that passed for wind on this world. A fringe of mushy ice lapped slothfully against the rock all around the shoreline, never quite managing to agglutinate into a solid sheet. The terminal glaciers that had emerged five million years ago to cap the northern and southern zones of the planet had slowly drained vast quantities of pure water out of the oceans, leaving a residue of water that became ever more salty with each passing century, correspondingly lowering its freezing point. Neither of the massive planetary encrustations had grown any larger for millennia now. With the star in its current state, Half Way’s environment had reached an equilibrium that would probably last for geological ages.

The airlock in the flying boat was large enough to hold all five passengers simultaneously as the atmosphere cycled. Mellanie took her helmet off as she walked into the forward cabin on the first deck. Her first impression was rows and rows of huge chairs stretching away down the brightly lit interior, like a small theater auditorium. There was a staff of eight waiting for them, and three times that many bots. She’d never seen anything like it before.

They were helped off with their suits and told to sit wherever they liked. Mellanie chose a window seat near the front, and was given a glass of bucks fizz by one of the stewardesses. “Now this is the way to travel,” she declared as the seat slid back and its footrest extended. Dudley looked around uncertainly, then gingerly allowed himself to sink back into the thick leather cushioning.

There were all the usual dull thuds associated with an aircraft preparing to take off, crates being loaded and secured, cargo hold doors closing, turbines starting up. The ends of the wings slowly bent down to the vertical, lowering the long bulbous tip floats ready for the water takeoff. Then they were rolling down the rock slope into the sea. More thuds as the undercarriage retracted, leaving them floating. They taxied sedately out of the inlet. The pilot used the PA to announce their ten-hour flight time and wished them a pleasant journey, and the nuclear turbines wound up to full thrust.

It was a surprisingly short takeoff run. Mellanie grinned excitedly as huge fans of spray curved out from behind the wingtip floats. Then they were surging up into the pink sky, applauded by the silent dazzling flashes of collapsing ions as they crashed into the neutron star forty million kilometers above them.

There was only one break in the monotony of the flight. Three hours in, the pilot spotted a pod of white whurwals far below, and lost altitude so the bored passengers could see them. They were little more than vermilion dots sliding through the darkling sea, almost twice the size of Earth’s blue whales. Unlike those terrestrial whales these were fantastically aggressive, pack creatures hunting down the gradually dwindling stocks of fish they shared their last arctic ocean with. They even fought with other pods as they swam around and around the equator between the constricting walls of Half Way’s terminal glaciers.

Twice Mellanie and Dudley left the forward cabin to consummate their membership in the mile-high club. They didn’t even have to use the cramped toilets for privacy. The middle and rear cabins on all three decks were empty and dark, giving them plenty of scope for misbehavior amid the long rows of vacant seats.
