Larry Niven - FALLEN ANGELS

High over the northern hemisphere the scoopship's hull began to sing. The cabin was a sounding box for vibrations far below the threshold of hearing. Alex MacLeod could feel his bones singing in sympathy.

Piranha was kissing high atmosphere.

Planet Earth was shrouded in pearl white. There was no break anywhere. There were mountain ranges of fluff, looming cliffs, vast plains that stretched to a far distant convex horizon, a cloud cover that looked firm enough to walk on. An illusion; a geography of vapors as insubstantial as the dreams of youth. If he were to set foot upon them… The clouds did not float in free fall, as was proper, but in an acceleration frame that could hurl the scoopship headlong into an enormous ball of rock and iron and smash it like any dream.

Falling, they called it.

Alex felt the melancholy stealing over him again. Nostalgia? For that germ-infested ball of mud? Not possible. He could barely remember Earth. Snapshots from childhood; a chaotic montage of memories. He had fallen down the cellar steps once in a childhood home he scarcely recalled. Tumbling, arms flailing, head thumping hard against the concrete floor. He hadn't been hurt; not really. He'd been too small to mass up enough kinetic energy. But he recalled the terror vividly. Now he was a lot bigger, and he would fall a lot farther.

His parents had once taken him atop the Sears Tower and another time to the edge of the Mesa Verde cliffs; and each time he had thought what an awful long way down it was. Then, they had taken him so far up that down ceased to mean anything at all.

Alex stared out of Piranha's windscreen at the cloud deck, trying to conjure that feeling of height; trying to feel that the clouds were down and he was up . But it had all been too many years ago, in another world. All he could see was distance. Living in the habitats did that to you. It stole height from your senses and left you only with distance.

He glanced covertly at Gordon Tanner in the copilot's seat. If you were born in the habitats, you never knew height at all. There were no memories to steal. Was Gordon luckier than he, or not?

The ship sang. He was beginning to hear it now.

And Alex MacLeod was back behind a stick, where God had meant him to be, flying a spaceship again. Melancholy was plain ingratitude! He had plotted and schemed his way into this assignment. He had pestered Mary and pestered Mary until she had relented and bumped his name to the top of the list just to be rid of him. He had won.

Of course, there was a cost. Victories are always bittersweet. Sweet because… He touched the stick and felt nothing. They were still in vacuum… thicker vacuum, that was heating up. If there wasn't enough air to give bite to the control surfaces, a pilot must call it vacuum.

How could you explain the sweetness to someone who had never conned a ship? You couldn't. He relaxed in the acceleration chair, feeling the tingling in his hands and feet. The itching anticipation. Oh, to be useful again, even if for a moment.

But bitter because… That part he did not want to think about. Just enjoy the moment; become one with it. If this was to be his last trip, he would enjoy it while he could. If everything went A-OK, he'd be back upstairs in a few hours, playing the hero for the minute or so that people would care. A real hero, not a retired hero. Then back in the day-care center wiping snotty noses. It would be years before another dip trip was needed. He'd never be on the list again.

Which meant that Alex MacLeod, pilot and engineer, wasn't needed any longer. So what do you do with a pilot when pilots aren't needed? What do the habitats do with a man who can't work outside, because one more episode of explosive decompression will bring on a fatal stroke?

Day care. Snotty noses. Work at learning to be a teacher, a job he didn't much like.

Look on the bright side, Alex, my boy. Maybe you won't make it back at all.

Sure, he could always go out the way Mish Lykonov had in Moon Rat, auguring in to Mare Tranquilitatis. They'd have a ceremony - -and they'd miss the ship more than him. Even Mary. Maybe especially Mary, since she'd got him the mission.

He straightened in his seat and touched the controls again. Maybe just a touch of resistance…

"Chto delayet? Alex!"

Something had prodded Gordon awake. Alex glanced to the right. "What is it?"

"I'm getting a reading on the air temperature gauge!"

"Right. There's enough air outside now to have a temperature."

Gordon nodded, still unbelieving.

Gordon had read the book. Come to that, Gordon read a lot of books, but books don't mean much. No one ever learned anything out of a book, anyway. This was why they always teamed a newbie with an old pro. Hands-on learning. The problem with on-the-job training for this job was that there was not a hell of a lot of room for trial and error. Alex moved the stick gently, and felt the ship respond. Not vacuum anymore! He banked and brought them up level, feeling the air rushing past just outside the skin. His eyes danced across the gauges. Here. There. Not reading them. Just a glance to see if something was wrong, or if something had changed since the last glance. Dynamic air temperature. Stagnation air temperature. The Mach number needle sprang to life, leaped from zero to absurdity, then hunted across the dial. A grin stretched itself across his face. No blues now. He hadn't forgotten at all; not a damned thing.

"What is funny?" Gordon demanded.

"Old war-horse heard the trumpet again. Now it's your turn. Take the stick." Fun was fun, but it was time for the kid to wrap his hands around the real thing. There was only so much you could do in a simulator. "There. Feel it?"

"Uh…" Gordon pulled back slightly on the copilot's stick. He looked uncertain.

He hadn't felt anything. "Take over," Alex growled. "You're flying the ship now. Can't you tell?"

"Well…" Another tentative move at the controls.

Piranha wobbled. "Hey! Yeah!"

"Good. Look, it's hard to describe, but the ship will tell you how she's doing if you really listen. I don't mean you should forget the gauges. Keep scanning them; they're your eyes and ears. But you've got to listen with your hands and feet and ass, too. Make the ship an extension of your entire body. Do you feel it? That rush? That's air moving past us at five miles per second. Newton's not flying us anymore. You are."

Gordon flashed a nervous grin, like he'd just discovered sex.

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

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