"What's our flight path?" Alex asked.

"Uh…" A quick glance at the map rollout. "Greenland upcoming."

"Good. Hate to be over Norway."

"Why?"

Why. Didn't the kid listen to the downside news broadcasts? Gordon, this is your planet! Don't you care? No, he probably didn't. It was his grandparents planet.

"There's war in Norway. If we flew over, somebody would cruise a missile at us sure as moonquakes, and we'd never even know which side did it."

The new tiling was wonderful. In the old days, the ship's skin would be glowing; but now… Four thousand degrees and no visible sign at all. Still, they'd be glowing like a madman's dream on an IR screen, new tiles or no, and that was all the Downers would need to vector in on.

"Which side?" Gordon mused. "What are the sides?"

Alex laughed. "That's one of the reasons we can't be sure. When it started, it was what was left of NATO defending the Baltics." Non-nuclear, but it just went on and on and on. Alex didn't really care who won any more than Gordon did. "After a while, the Scandinavians and the Russians took a nervous look over their shoulders at the glaciers, and East versus West became North versus South."

"Silly bastards. Nye kulturni."

"Da." It didn't surprise him anymore. All the younger Floaters spoke Russian as automatically as English. Russlish? Ever since Peace and Freedom had pooled their resources, everyone was supposed to learn each other's language; but Alex hadn't gotten past "Ya tebye lyublyu." Hello was "zdravstvuitye." Alex thought there was something masochistic about speaking a language that strung so many consonants together. "Be fair, Gordon. If you had ice growing a mile thick in your backyard, wouldn't you want to move south?"

Gordon mulled it. "Why south?"

He couldn't help the grin. "Never mind. Let me take her again. Hang on, while I kill some velocity. Watch what I do and follow me." He stroked the stick gently.

Here we go, baby. You'll love this. Drop the scoop face-on to the wind. Open wide. That's right. Spread your tail, just for a moment… Alex realized that his lips were moving and clamped them shut. The younger ones didn't understand when he talked to the ship. Gordon was having enough trouble feeling the ship. "Okay," he said finally, "that's done. Take over, again."

Gordon did, more smoothly than before. Alex watched him from the corner of his eye while pretending to study the instruments. Piranha was a sweet little ship. Alex had flown her once, years before, and considered her the best of the three remaining scoopers. Maybe that was just Final Trip nostalgia. Maybe he would have felt the same about whichever ship he flew on his last dip; but he would shed a special tear for Piranha when they retired her. The scoopers were twenty-two years old already and, while there was not much wear and tear parked in a vacuum, screaming through the Earth's atmosphere like a white hot banshee did tend to age the gals a bit. Jaws was already retired. Here was Gordon at nineteen, just getting started; and the ships at twenty-two were ready to pack it in. Life was funny.

Alex ran a hand lightly across the instrument panel. Scoopships were pretty in an ugly sort of way: lifting bodies with gaping scoops that made them look like early jet airplanes. They could not land--no landing gear--but they didn't dip into the atmosphere deeply enough for that to matter. But they were the hottest ships around.

Piranha skimmed above the glare-white earth as hot as any meteor, but never too hot at any point. Humming, vibrating, functional.

Gordon was functional too. Alert, but not tense; holding her nose just right while flame-hot air piled through the scoop and bled into the holding tank. The velocity dropped below optimum on the dial and Gordon bled some of the air into the scramjet and added hydrogen until the velocity rose again. He did it casually, as if he did this sort of thing every day. Alex nodded to himself. The kid had it. He just needed it coaxed out of him.

"Alex?" Gordon said suddenly. "Why not Greenland?"

"Hmm?"

"Why isn't anyone in Greenland shooting missiles?"

Alex grinned. That was good. Gordon was flying a scoopship on a dip trip, sucking air at five miles per, and trying to make casual conversation. That's right, Gordo. You can't do this sort of thing all tensed up; you've got to be relaxed.

"Nobody there but Eskimos," he explained. "An Ice Age doesn't bother them any. Hell, they probably think they've all died and gone to Inuit Heaven."

"Eskimos I do not know. Gogol once wrote good story that speaks of Laplanders but I did not understand--" The sky had turned from black to navy blue. Wouldn't want to get any lower. Gordon glanced out the windscreen and said, "Shouldn't we be seeing land by now?"

Alex shook his head, realized Gordon wasn't looking at him and answered. "No, the cloud-deck off the pole…" He stopped. The white below them wasn't the cloud shroud any more. They must have gone past the southern edge or hit a hole in it. White on white. Cloud or ice. If you didn't actually look you, might not notice. "Damn, damn. The ice is still growing."

Gordon didn't say anything. Alex watched him a moment longer then turned his attention to the gauges. Gordon was nineteen. There had always been an Ice Age, so it did not surprise him that the glaciers had crept farther south. Alex thought he remembered a different world--green, not white--before his parents brought him upstairs. He wasn't sure how much of it was genuine childhood memories and how much was movies or photographs in books. The habitats had a fair number of books on tape, brought up when they still got along with the Downers.

The green hills of earth, he thought. Now the glaciers--not rivers of ice, but vast oceans of ice--were spreading south at tens of miles a year. Hundreds of miles in some places. In the dictionary, "glacial" meant slow; but Ice Ages came on fast. Ten thousand years ago the glaciers had covered England and most of Europe in less than a century. They'd known that since the sixties… though no one had ever seen fit to revise his schoolbooks. But what did that matter? To a school kid a century was forever anyway.

As for Gordon… He glanced again at his copilot. Well, what the world is like in our lifetimes is what it should be like forever. As it was in the beginning, is now, and ever shall be. It was funny to think of groundside environmentalists desperately struggling against Nature, trying to preserve forever the temporary conditions and mayfly species of a brief interglacial. Alex looked again through the cockpit windscreen and sighed.

"We could have stopped it," he said abruptly.

"Eh?" Gordon gave him a puzzled glance.

"The Ice Age. Big orbiting solar mirrors. More microwave power stations. Sunlight is free. We could have beamed down enough power to stop the ice. Look what one little SUNSAT has done for Winnipeg."

Gordon studied the frozen planet outside. He shook his head. "Ya nye ponimal," he admitted. "I faked the examiners, but I never did get it. The what-did-they-call-it, polar ice cap? It stayed put for thousands of years. Then, of a sudden it reaches out like vast white amoeba."

All of a sudden, Alex's earphones warbled. He touched a hand to his ear. "Piranha here."

"Alex!" It was Mary Hopkins's voice. She was sitting mission control for this dip. Alex wondered if he should be flattered… And if Lonny was there with her. "We've got a bogey rising," said Mary. "Looks like he's vectoring in on you."

So, they don't shoot missiles out of Greenland? Find another line of work, Alex-boy; you'll never make it as a soothsayer. "Roger, Big Momma." He spun to Gordon. "Taking over," he barked. "Close the scoop. Seal her up. Countermeasures!"
