True enough, she thought. I'll never be able to land, not in the world I knew.

"Getting sentimental about the old computers?"

Elouise, startled, turned in her chair and faced her husband, Charlie. At that moment the airplane lurched, but like sailors accustomed to the shifting of the sea, they adjusted unconsciously and did not notice the imbalance.

"Is it noon already?" she asked.

"It's the mortal equivalent of noon. I'm too tired to fly this thing anymore, and it's a good thing Bill's at the controls."

"Hungry?"

Charlie shook his head. "But Amy probably is," he said.

"Voyeur," said Elouise.

Charlie liked to watch Elouise nurse their daughter. But despite her accusation, Elouise knew there was nothing sexual in it. Charlie liked the idea of Elouise being Amy's mother. He liked the way Amy's sucking resembled the sucking of a calf or a lamb or a puppy. He had said, "It's the best thing we kept from the animals. The best thing we didn't throw away."

"Better than sex?" Elouise had asked. And Charlie had only smiled.

Amy was playing with a rag doll in the only large clear space in the airplane, near the exit door. "Mommy Mommy Mamommy Mommy-o," Amy said. The child stood and reached to be picked up. Then she saw Charlie. "Daddy Addy Addy."

"Hi," Charlie said.

"Hi," Amy answered. "Ha-ee." She had only just learned to close the diphthong, and she exaggerated it. Amy played with the buttons on Elouise's shirt, trying to undo them.

"Greedy," Elouise said, laughing.

Charlie unbuttoned the shirt for her, and Amy seized on the nipple after only one false grab. She sucked noisily, tapping her hand gently against Elouise's breast as she ate.

"I'm glad we're so near finished," Elouise said. "She's too old to be nursing now."

"That's right. Throw the little bird out of the nest."

"Go to bed," Elouise said.

Amy recognized the phrase. She pulled away. "La-lo," she said.

"That's right. Daddy's going to sleep," Elouise said.

Elouise watched as Charlie stripped off most of his clothing and lay down on the pad. He smiled once, then turned over, and was immediately asleep. He was in tune with his body. Elouise knew that he would awaken in exactly six hours, when it was time for him to take the controls again.

Amy's sucking was a subtle pleasure now, though it had been agonizing the first few months, and painful again when Amy's first teeth had come in and she had learned to her delight that by mpping she could make her mother scream. But better to nurse her than ever have her eat the predigested pap that was served as food on the airplane. Elouise thought wryly that it was even worse than the microwaved veal cordon bleu that they used to inflict on commercial passengers. Only eight years ago. And they had calibrated their fuel so exactly that when they took the last draft of fuel from the last of their storage tanks, the tank registered empty; they would burn the last of the processed petroleum, instead of putting it back into the earth. All their caches were gone now, and they would be at the tender mercies of the world that they themselves had created.

Still, there was work to do; the final work, in the final checks. Elouise held Amy with one arm while she used her free hand slowly to key in the last program that her role as commander required her to use. Elouise Private, she typed. Teacher teacher I declare I see someone's underwear, she typed. On the screen appeared the warning she had put there: "You may think you're lucky finding this program, but unless you know the magic words, an alarm is going to go off all over this airplane and you'll be had. No way out of it, sucker. Love, Elouise."

Elouise, of course, knew the magic words. Einstein sucks, she typed. The screen went blank, and the alarm did not go off.

Malfunction? she queried. "None," answered the computer.

Tamper? she queried, and the computer answered, "None."

Nonreport? she queried, and the computer flashed, "AFscanP7bb55."

Elouise had not really been dozing. But still she was startled, and she lurched forward, disturbing Amy, who really had fallen asleep. "No no no," said Amy, and Elouise forced herself to be patient; she soothed her daughter back to sleep before pursuing whatever it was that her guardian program had caught. Whatever it was? Oh, she knew what it was. It was treachery. The one thing she had been sure her group, her airplane would never have. Other groups of Rectifiers-- wreckers, they called themselves, having adopted their enemies' name for them-- other groups had had their spies or their fainthearts, but not Bill or Heather or Ugly-Bugly.

Specify, she typed.

The computer was specific.

Over northern Virginia, as the airplane followed its careful route to find and destroy everything made of metal, glass, and plastic; somewhere over northern Virginia, the airplane's path bent slightly to the south, and on the return, at the same place, the airplane's path bent slightly to the north, so that a strip of northern Virginia two kilometers long and a few dozen meters wide could contain some nonbiodegradable artifact, hidden from the airplane, and if Elouise had not queried this program, she would never have known it.

But she should have known it. When the plane's course bent, alarms should have sounded. Someone had penetrated the first line of defense. But Bill could not have done that, nor could Heather, really-- they didn't have the sophistication to break up a bubble program. Ugly-Bugly?

She knew it wasn't faithful old Ugly-Bugly. No, not her.

The computer voluntarily flashed, "Override M577b, commandmo4, intwis CtTttT." It was an apology. Someone aboard ship had found the alarm override program and the overrides for the alarm overrides. Not my fault, the computer was saying.

Elouise hesitated for a moment. She looked down at her daughter and moved a curl of red hair away from Amy's eye. Elouise's hand trembled. But she was a woman of ice, yes, all frozen where compassion made other women warm. She prided herself on that, on having frozen the last warm places in her-- frozen so goddamn rigid that it was only a moment's hesitation. And then she reached out and asked for the access code used to perform the treachery, asked for the name of the traitor.

The computer was even less compassionate than Elouise. It hesitated not at all.

The computer did not underline; the letters on the screen were no larger than normal. Yet Elouise felt the words as a shout, and she answered them silently with a scream.

Charles Evan Hardy, b24ag61-richlandWA.

It was Charlie who was the traitor-- Charlie, her sweet, soft, hard-bodied husband, Charlie who secretly was trying to undo the end of the world.

God has destroyed the world before. Once in a flood, when Noah rode it out in the Ark. And once the tower of the world's pride was destroyed in the confusion of tongues. The other times, if there were any other times, those times are all forgotten.

The world will probably be destroyed again, unless we repent. And don't think you can hide from the angels. They start out as ordinary people, and you never know which ones. Suddenly God puts the power of destruction in their hands, and they destroy. And just as suddenly, when all the destruction is done, the angel leaves them, and they're ordinary people. Just my mother and my father.

I can't remember Father Charlie's face. I was too young.

Mother Elouise told me often about Father Charlie. He was born far to the west in a land where water only comes to the crops in ditches, almost never from the sky. It was a land unblessed by God. Men lived there, they believed, only by the strength of their own hands. Men made their ditches and forgot about God and became scientists. Father Charlie became a scientist. He worked on tiny animals, breaking their heart of hearts and combining it in new ways. Hearts were broken too often where he worked, and one of the little animals escaped and killed people until they lay in great heaps like fish in the ship's hold.
