McVary continued to transmit the distress signal, though his speech and thoughts were fragmented. He sucked hard on the oxygen mask as he spoke, and blood collected in his mouth and he had to swallow it.
McVary knew that the oxygen mask alone was not enough. Without a sustaining pressure to force the oxygen into and through his lungs, it was almost totally useless. The flight deck’s emergency oxygen canister, behind Fessler’s panel, could just as well be back in San Francisco for all the good it was doing them. Only a military pressure suit—a space suit—of the type he had once worn could exert the necessary pressure on his body so that he could breathe. But he knew that even if he had one, there would not have been enough time to hook it up.
Dan McVary, who as a young man had flown exotic military jets through wild maneuvers, was suddenly more frightened than he had ever been. How had this happened? Commercial transports were not supposed to completely decompress the way military craft did when they were hit in combat. The possibility of sudden decompression was so slight that it had been ignored by the aeronautical engineers who built the Straton. There were no air-lock doors or pressure bulkheads between the sections as there were watertight compartments on a ship or airtight compartments on modern dirigibles. These safety features were too heavy for an airliner. Too costly. A complete decompression was not supposed to happen. But it had. How? He wondered if airtight compartments would have helped anyway. The image of theTitanic with its so-called watertight compartments flashed through his mind. Engineering marvels … every contingency planned for … only a set of the most … the most unusual circumstances … his head was splitting and he felt a coldness deep down in his body that chilled him in a way he had never felt before. Dan McVary knew he was dying.
Captain Stuart’s vision began to blur. He pushed his face forward to read the digital clock. Over a minute had passed since he felt the jolt. The Straton was still on autopilot and was beginning to descend very rapidly. He could see that the vertical descent rate had increased to 12,000 feet per minute. They passed through 53,000 feet. The cabin pressure was up to 45,000 feet. They were definitely not going to get down to a level where the oxygen masks could be used in time to save anyone who was still able to use them. They would not get into the naturally breathable atmosphere for several minutes after that. He shook his head. They were all dead.
For an instant, Stuart considered the passengers. They were his responsibility. But there was nothing he could do, or even say. There were no slow sinkings on an aircraft, no dramatic speeches from the captain, no leisurely good-byes or farewell toasts. There were only a few minutes or seconds of horror, then death.
In the tourist cabin, the noise from the wind and escaping air had lessened considerably as the inside and outside pressure approached equilibrium. People could hear each other now, but there was very little talking. Most people sucked hard on their released overhead oxygen masks, inhaling and exhaling deeply, puzzled by the absence of that familiar feeling of having taken a good deep breath.
A coldness permeated the cabin and deepened the effects of shock and increased the effects of oxygen deprivation. Layers of condensed moisture formed along the ceiling, caused by the natural onboard water vapor that had suddenly been squeezed out by the reduced cabin pressure. The passengers stared up at these forming clouds, unsure of what they were or what they meant.
Someone yelled, “Fire!” and some people screamed, but most remained silent, accepting this new aberration, too numbed and disoriented to react. The cloud moved through the cabin like a sea fog rolling into a coastal city, casting an amorphous gray haze over the silent people. The cabin lights shone with an unearthly luminescence through the cloud. Eerie white ice particles began forming on the walls and windows. Near the starboard hole there was a brief snow flurry.
The moisture dissipated and the cabin atmosphere became dry except for the breath fog still exhaled by the living and the blood pouring from the open wounds of the dying. Blood and breath crystallized and formed frosts of red and white wherever they touched a freezing surface.
The outside sounds of the four Straton engines and the airflow past the gaping holes grew louder as the sound of the outward-rushing air lessened. These new noises filled the tourist cabin and drowned out the weak moans of the injured.
An uncounted number of people were dead or dying, and most of the rest were in shock. But it appeared that the worst of the ordeal was over. The aircraft was still flying and showed no visible signs of crashing. A strange calm, a pleasant languor simulating the effects of alcohol or tranquilizers, took hold of the passengers of Flight 52 as the first effects of oxygen deprivation began to register. There was still the pain behind the eyes, in the ears, but it did not seem so acute now.
Captain Stuart pressed his face against his console. Everything appeared dark in the cockpit, but he could see that the instrument lights were working. They shone like dying suns in a faraway galaxy, yet they seemed to emit no light beyond their surface. He read the two altimeters. Aircraft altitude was 51,000 feet, and descending. Cabin altitude was also 51,000 feet and descending now with the aircraft. The cabin differential pressure was zero. Inside was outside. Outside was inside.
The autopilot was taking the aircraft down, as fast as it could safely go, into the thicker atmosphere at 30,000 feet where they would find enough ambient pressure to make the oxygen masks workable. The rate of descent was racing against the physiological effects of anoxia—suffocation—and suffocation was winning. Stuart could see no way out of it. All the numbers—airspeed, altitude, rate of descent, rate of pressure loss—had been predictable. He knew the numbers before he had ever stepped into the cockpit of his first Straton.If only the damned hole had been smaller …
In the first-class lounge, an elderly man, John Thorndike, released his seat belt and quickly stood. A familiar sensation gripped his chest and he reached for a pillbox in his jacket. He paled, then turned blue as his heart gave out. He tottered for a moment, then fell forward across the cocktail table, landing on his wife, who tried to scream but couldn’t.
In the tourist and first-class cabins, older people began dying. Some slipped away noiselessly, others moaned their protests as hearts and lungs failed.
Throughout the aircraft, the old, then those with preexisting medical conditions began to die. Lungs collapsed, hearts gave up, thin blood vessels burst, and hemorrhaging blood poured from all the body orifices. Internally hemorrhaging blood collected in skulls and body cavities causing a more painful death. Pockets of pressurized air developed in body cavities, and people began clawing at their faces and torsos, irrationally trying to get at the source of the pain.
Everyone, young and old, weak and healthy, experienced hyperventilation, dizziness, blurred vision, and nausea. People choked on their vomit when oxygen-deprived brains and muscles failed to respond to the vomiting reflex. Skin colors went from white to blue. Bowels and bladders released, and if normal breathing and its adjunct, the sense of smell, had been possible, the cabin would have reeked.
More and more people had given up on the masks, but many people still tried desperately to suck from them, silently cursing what they thought was a failure of the system to provide oxygen. But the oxygen was there. The molecules poured out of the masks and swirled around their faces like a cruel joke, then dissipated into the low-pressure atmosphere.
In the freezing tourist cabin, where anyone who cared to look could see the holes, sunlight poured in through the south-facing port-side hold and starkly illuminated the rubble and carnage left in the wake of the missile.
By this time, everyone who was capable of forming thought knew they were suffocating. Yet outside, through the holes, they could see the unlimited sky, a cloudless deep blue, bright with sunlight. It looked balmy, enchanting, but it was as lethal as the bottom of the sea.
Captain Stuart was barely conscious. He moved his head to his right. McVary was still sitting upright, staring straight ahead. He turned his head and looked back
at Stuart with an odd expression. Stuart turned his head away and looked over his shoulder. Fessler was still lying across his desk in a pool of blood. The bleeding seemed to have stopped.
Stuart’s fingers were numb and his limbs were heavy. His brain seemed detached from his body and he felt as though he were free-floating.
The cells in his brain were dying, but one shining thought, like a faraway landing beacon, was becoming increasingly clear in the darkening cockpit. Ever since he had begun to fly the Straton, the thought of high-altitude decompression had played on his mind and he had formulated a response to this possibility that was so ingrained that it had not yet died or become jumbled like everything else. He knew he must shut off the autopilot and push the aircraft into a sudden dive. It was all coming to him now. He had it.If they did not all die quickly and someone in the cockpit was still functioning when the aircraft descended into the breathable air, then that person might have enough intellect left to put the aircraft down somewhere . He looked at McVary again. Young. Good health. Sucking hard on his mask. Half his brain might survive. The idiot would save them from death and condemn them to that shadowy place, that place of perpetual eclipse, that state of being which is called half-life—speechless, blind, paralyzed, dim-witted. He thought of his wife and family.Oh, God. No .
Stuart reached his hand out toward the autopilot release button on the control wheel. No good. McVary might turn it on again. He pushed his hand toward his console and found what he wanted—the autopilot master switch, which was not duplicated on the copilot’s side. He pushed his hand over the guarded cover of the switch and rolled it back. His fingers found the small toggle.
He hesitated. The instinct for survival—any kind of survival—began overtaking his fading intellect. He had to act quickly.Quickly! Act what? He tried to remember what he was supposed to act on, then remembered for a flash of a second and tugged on the switch. It held fast. He recalled clearly that the solenoid was designed to require a good deal of force to shut down the auto …auto what? What?
Captain Alan Stuart sat back in his seat and stared out the windshield. He frowned. He had a headache. Something was bothering him.Coffee. Brazil . He had to go to Brazil for coffee. He smiled. A small trickle of saliva ran down his chin.
The automatic pilot continued to steer the Straton 797 through its programmed emergency descent. Its electronic memory bank and preset responses were in no way affected by the oxygen deprivation. Never once did it consider the effects of anoxia on its human charges. It was true that one young creator of this autopilot had suggested once that a sudden and complete decompression at altitudes of over 50,000 feet should induce a shutdown of the autopilot. But that young man no longer designed autopilots and his “self-destruct response,” as the Straton executives had labeled it, was not part of the autopilot’s repertoire. The autopilot could and would descend to 11,000 feet where the air was breathable and warmer, and would continue piloting the Straton on its flight path to Tokyo. It could do that and more. The thing it could not do was land the plane, not without additional inputs from the crew.

John Berry felt the effects of the rarefied atmosphere. He had begun to hyperventilate. His head ached painfully and he was dizzy. He sat on the small commode until he felt a little better.
He rose again and pulled at the door. It was still firmly stuck. He felt too weak to try it again. He glanced at his watch on the shelf. 11:04. Only two minutes had gone by since he had felt the bump. It seemed longer.
Berry began pounding on the door. “Open up! Open the damn door! I’m stuck in here!” He put his ear to the door. Odd sounds were coming from the cabin. He pounded again, then sank back against the bulkhead. He wanted to try the door again, but decided to wait until he felt stronger.
John Berry knew that if the aircraft made an emergency landing in the ocean, he would not be able to get to the life rafts. He would drown when the aircraft sank. He put his hands to his aching head, bent over, and vomited on the floor, disregarding the commode. He straightened up and inhaled deeply several times, but a light-headedness rolled over him like a giant wave. He wanted to wash his face and mouth, but remembered that the tap had run dry.Why?
The lavatory seemed to get darker, and he felt weaker. He slipped to the floor. His transition to unconsciousness came slowly, and he allowed his body to untense. He felt a strange euphoria and decided that death would not be that bad. He had never thought it would be. He recalled his childhood, which did not surprise him, even thought of his children, which made him feel less guilty about the way he felt about them. He remembered Jennifer, the way she once was. He closed his eyes and lapsed into blackness.
The vent in the lavatory continued to send a steady stream of pressurized and heated air into the enclosed space. The pressure leaked out around the edges of the door, but it leaked slowly, slowly enough to keep a pressure of over two pounds per square inch on the door, sealing it shut. The pressure loss was also slow enough so that the atmosphere in the lavatory never rose above 31,000 feet.
John Berry lay crumpled on the floor, breathing irregularly. Five more minutes at the altitude of 31,000 feet would cause him permanent and irreversible brain damage. But the Straton’s autopilot was bringing the airliner down rapidly.
* * *
In the tourist cabin, the first-class cabin, the first-class lounge, and the cockpit, the passengers and crew of Trans-United’s Flight 52 had fallen, one by one, into a deep, merciful sleep; the level of oxygen being supplied to their brain cells had dropped too low for too long.
* * *
At 11:08A.M. , six minutes after the Phoenix missile had passed through the Straton 797, the airliner reached 18,000 feet. The autopilot noted the altitude and began a gradual recovery from the emergency descent. The speed brakes were automatically retracted, followed by a slow and steady autothrottle power advance to the four engines.
In the cockpit three figures sat slumped over, strapped to their seats. The two control wheels moved in unison, the four throttles advanced, the ailerons made slight and continuous adjustments. The aircraft was flying nicely. But this was no ghost ship, no Flying Dutchman; it was a modern aircraft whose autopilot had taken charge as it was told to do. Everything would be fine, at least for a while.
As the autopilot’s electronic circuitry sensed the proximity of the desired altitude, it leveled out the giant airliner and established it at an altitude of 11,000 feet and a slow, fuel-saving speed of 340 knots. The air-pressurization system had automatically disengaged as the aircraft sank into the thicker atmosphere. The fresh sea breezes of clean Pacific air filled the cabin of Trans-United’s Flight 52.
A few minutes after leveling off, the first passengers began to awaken from their unnatural sleep.

Lieutenant Peter Matos flew his F-18 fighter on a straight and level course. Reluctantly, he pushed his radio-transmit button. “Homeplate, this is Navy three-four-seven.” He continued to hold down on the transmit button so he could not receive a reply from theNimitz until he was ready to deal with it. His mind whirled with conflict. Something was still not quite right. Finally, he slid his finger off the button, which freed the channel so he could receive their reply.
“Roger, Navy three-four-seven. We have also registered the intercept,” Petty Officer Kyle Loomis answered. Matos knew that the carrier had been equipped to monitor the missile, and that the men in electronics Room E-334 had watched the needle that registered the sudden end-of-transmission from the AIM-63X as it had impacted against the target, destroying its transmitter.
“Navy three-four-seven, this is Homeplate.”
The voice in Matos’s earphones was unmistakably that of Commander Sloan. Even though a special encoding voice scrambler was being used to prevent anyone else from monitoring their channel, the deep and measured qualities of Sloan’s voice came through. Matos discovered that he had suddenly braced himself, as if he had run across Sloan in one of theNimitz ’
s below-decks corridors.
“We are receiving conflicting signals,” Sloan said.
Matos sensed a growing anger at the edges of Sloan’s voice. He had never personally experienced a run-in with the Commander, but too many of the other pilots had. Sloan’s wrath was legendary.Don’t get jumpy , Matos said to himself.It’s just an electronic echo that makes him sound that way. Keep your mind on the job .
“Our monitors agree with your report of missile impact. But we’re still monitoring the target drone,” Sloan continued. “Its condition reads as steady. That conflicts with the Phoenix’s readout. Do you have the engagement area in good radar resolution?”
Matos slumped lower in the cockpit seat to the limits that his cinched-up harness would allow. His heart sank with the words, and he could taste the bile from the pit of his stomach.Christ Almighty, Mother of God . He moistened his lips and cleared his throat before pressing the transmit button. “Roger, Homeplate. This is three-four-seven. I’m beginning to get the impact zone in good resolution. Stand by.”
James Sloan had no intention of being put off, even momentarily, by one of his subordinates. “Three-four-seven, execute a radar lock-on with the Phoenix,” he transmitted. “The test missile must have failed before it engaged the target. That would explain why we still read the target drone.”
“Roger, Homeplate.” But Matos knew that the Phoenix had hitsomething . He had watched the radar tracks converge. He also knew that theNimitz ’s shipboard radar could not see the impact area. The carrier was hundreds of miles astern of his F-18, which put it out of radar range of the test site. All that the carrier people would be able to tell from the equipment in the electronics room was that there was no longer any radio signal coming from the test missile, and that the target drone continued, inexplicably, to send a loud-and-clear transmission.
