Reckoning by the Dead

The compass deviation card was mounted on a brass clip beside the instrument panel, and Ilsa read it the way she read it before every flight — not because the numbers changed, but because the act of reading them was the beginning of a contract between herself and the machine. At heading 030, the compass lied by two degrees east. At 120, three degrees west. At 210, one degree east again. Every heading had its own particular dishonesty, catalogued in pencil on a card no larger than a man’s palm, and she corrected for these dishonesties automatically, the way a person might correct for the known tendencies of their own character — the impulse to generosity that is really vanity, the patience that is really fear. You did not eliminate the errors. You knew them, and you flew with them, and the knowing was the craft.

She tightened the last engine cowling fastener and wiped her hands on a rag that had once been someone’s shirt. The Gipsy Moth sat on the apron at Wilson Airfield in the dark before dawn, its fabric wings damp with Nairobi dew, its exhaust stubs cold. A single lamp burned in the dispatch hut. The rest of the field was shapes and suggestion — the silhouettes of parked aircraft, the hump of a fuel bowser, the wooden wind T on its pole turning slowly in a breeze too light to feel on the skin.

Abdi came out of the dispatch hut carrying a canvas satchel and a clipboard. He was Somali, thin, precise in his movements, and he had been dispatching flights from Wilson since before Ilsa arrived in the colony eight years ago, when she was twenty-three and had come from Copenhagen with a license, a broken engagement, and the particular clarity of a person who has learned that doing everything correctly does not oblige the world to produce the correct result. She had come to fly, and she flew. The reasons she had left Denmark remained in Denmark, and she did not visit them.

Abdi held the satchel at a slight distance from his body, as though the object were not yet his responsibility and he wished to mark the moment of transfer clearly.

“Polyvalent antivenom,” he said. “Six vials. Packed in kapok. Do not drop them.”

“I have never dropped anything, Abdi.”

“There is a first occasion for every failure. The manifest.” He held out the clipboard. She signed it. The cargo was for a soda-extraction camp on the southern shore of an alkaline lake in the Rift Valley — a place she had visited once before, six months ago, ferrying replacement parts for the camp’s rail spur. The man who needed the serum was the camp’s European overseer, a Dutchman named Grijs, who had been bitten on the right hand by a puff adder sometime in the previous twelve hours. The radio message had been garbled. The details were few. The urgency was plain.

She stowed the satchel behind the rear cockpit seat, threading the securing straps through its handles and pulling them tight. The antivenom was polyvalent — not specific to the puff adder but general, calibrated to the average crisis rather than the particular one.

She checked the fuel — both wing tanks full, forty-two gallons, enough for four and a half hours in still air. The flight to the lake was three hours. The margin existed, but only if the air cooperated, and the air did not recognize margins.

She pulled the propeller through twice to prime the cylinders, then climbed into the cockpit. The leather seat was cold. The instrument panel was a row of dim faces in the pre-dawn: altimeter, airspeed, oil pressure, fuel gauge, compass. She set the compass heading, corrected for deviation, and pressed the starter. The Gipsy Moth’s engine caught on the second blade, coughed, and settled into its idle — a sound she had heard a thousand times and which each time contained, for the first three seconds, the possibility that it would not continue.

Abdi stood clear and raised one hand. She did not wave back. She opened the throttle and the Moth rolled forward, its tailskid scraping the packed earth of the apron, and she turned onto the grass strip and ran the engine up against the brakes, checking the magnetos, the oil temperature, the rpm drop on each side. Both clean. She released the brakes and the Moth gathered itself and ran, the tail lifting first, the wings biting air, and the wheels left the ground at the point they always left the ground, and the earth fell away below her and became a different thing — a surface instead of a world, a map instead of a place.

She climbed south over Nairobi in the grey light. The city was a scatter of tin roofs and jacaranda trees, the Norfolk Hotel, the cathedral, the Somali quarter, the railway station — all of it reduced to pattern and color, and the people in the streets were not people but suggestions of movement, and she was not Ilsa Rask from Copenhagen but a weight in a machine, and the machine was the only real thing, and the air held her up not out of kindness but out of physics.

The Ngong Hills passed beneath her twenty minutes later — four dark humps against the eastern sky, their ridgelines sharp, the Maasai cattle trails running along the crest like pale veins on the back of a hand. Beyond them the land opened and fell. The plateau gave way to thorn scrub and red earth, scattered acacias throwing long shadows in the early light, and then the first hint of the Rift Valley escarpment — not visible yet as a feature, but perceptible as a change in the quality of the air, a thermal shift, the landscape tilting away from her in a manner the altimeter would register before the eye.

She had flown this route five times. Twice to the camp, three times to other settlements strung along the valley floor like beads on a wire too thin to hold them. Settlers, missionaries, a geologist once. They lived in places that could be reached by airplane and by nothing else that travelled faster than a person on foot, and when they needed something — medicine, parts, mail, another human face — they radioed Nairobi and Nairobi sent Ilsa or one of the other charter pilots, and the pilot flew three or four or six hours across country that was old when the pyramids were new, and delivered the package, and flew back. A letter has no memory of the mailbag. A vial of antivenom carries no trace of the weather.

Forty minutes south of Nairobi, past the dark shoulders of the Ngong Hills, the weather changed.

It did not arrive gradually. The convective cloud built across her route in a wall — a line of cumulonimbus running east to west along the edge of the Rift Valley escarpment, their tops white and anviled in the high sun, their bases dark and trailing columns of rain that from this distance looked solid, structural, as though the clouds were pillars holding up something above them that she could not see. She had flown into weather before and she would fly into weather again and there was no decision to make about it, only a calculation. She could not climb above — the Gipsy Moth’s service ceiling was twelve thousand feet and the cloud tops were higher. She could not fly around — the line extended to both horizons and the fuel did not permit the detour. She could descend below the cloud base and fly beneath the weather, reading the ground for landmarks, navigating by what she could see.

Or she could navigate by what she could not.

She made the decision the way decisions are made at eighty-five miles per hour in an open cockpit: with the hands first, the mind after. The stick went forward. The nose dropped. The altimeter needle began its counterclockwise turn — seven thousand, six-five, six thousand — and the grey closed around her like water filling a jar.

She descended to six thousand feet and the cloud swallowed her. The world outside the cockpit became grey and featureless — not dark, not light, but the color of nothing, the color of air made visible, which is the most disorienting color there is because it is the color of the medium you rely on and you cannot tell whether it is ten feet deep or ten thousand. The rain began. Not heavy, but steady, and it ran along the windscreen in lines that the slipstream distorted into shapes that looked, if you were tired enough, like writing.

She switched to dead reckoning.

The technique was simple and the execution was not. You took your last known position — in this case, the southern edge of the Ngong Hills, which she had identified before entering the cloud. You took your compass heading, corrected for deviation and for wind drift, and you calculated your groundspeed from your airspeed and the estimated wind. You noted the time. And then you flew — blind, steady, trusting the arithmetic — and you waited until the arithmetic said you had arrived, and then you descended, and the ground was either where you expected it to be or it was not. There was no confirming signal. No landmark emerging from the grey to tell you the numbers had held. You believed the numbers because you had put them there yourself, and if they were wrong, the wrongness was yours, and the ground would deliver the verdict, and the verdict was not an opinion.

The compass read 198, which meant 200 corrected. The wind was from the east, she guessed, fifteen knots — a crosswind that would push her west. She corrected five degrees to compensate. The airspeed indicator read eighty-five miles per hour. Subtract the headwind component — call it eight knots — and the groundspeed was roughly seventy-seven. From the Ngong Hills to the Loita Hills was sixty miles, which at seventy-seven miles per hour was forty-seven minutes. After the Loita Hills, the land dropped into the Rift Valley, and the lake was another forty miles south-southwest. She would see the escarpment when she cleared the cloud, if she cleared it, if the weather broke over the valley the way it usually did.

These were the numbers. She wrote them on the kneepad strapped to her thigh, and then there was nothing to do but hold the heading and wait. The engine ran. The compass turned on its pivot in its bowl of kerosene, and the numbers on its face moved and settled and moved again, and the rain came in through the gap where the windscreen met the cowling and wet her gloves. The gloves were leather, lined with cotton, and when the cotton was wet the leather stiffened, and her grip on the control stick became a negotiation between the rigidity of the gloves and the small corrections the stick demanded — corrections of inches, fractions of inches, the language of flight being spoken in a dialect too subtle for anyone not holding the stick to hear.

At the twenty-minute mark the engine began to run rough.

It was not dramatic. A hesitation in the firing — a missed beat, as though the engine had forgotten a word in a sentence it had been reciting for hours. Then smooth again. Then the hesitation, longer this time. She leaned the mixture and the engine smoothed. Then it roughened again. Water in the fuel, perhaps. Or ice in the carburetor throat, though the temperature was marginal for that. Or something else, something in the machine’s own privacy that she could not diagnose from the cockpit, because an engine does not explain itself, it only performs or fails to perform, and the pilot interprets the performance the way a doctor interprets a fever — by symptom, by pattern, by what this particular body has done before.

She checked the fuel pressure. Normal. Oil pressure. Normal. The engine caught again, ran smooth for thirty seconds, then missed. She applied carburetor heat. The engine roughened further — which was correct, because the heated air was less dense — and then, after a long moment in which she counted to eleven, it smoothed. She held the heat on. The rpm dropped by fifty. The groundspeed dropped with it. Her forty-seven-minute calculation was wrong now. She erased the number on the kneepad and wrote a new one. Fifty-two minutes. The margin grew thinner.

There is a particular quality to flying alone in cloud with a sick engine that cannot be explained to someone who has not done it. It is not fear, exactly, though fear is present the way moisture is present in air — distributed, invisible, everywhere. It is something closer to a negotiation conducted in silence between yourself and your own competence. You have trusted the arithmetic. The arithmetic has not yet failed you. But the engine that carries the arithmetic forward through space is coughing, and below the coughing engine is ground you cannot see, and somewhere on that invisible ground are rocks and thorn trees and the dry riverbeds that from altitude look like cracks in old pottery, and the distance between you and those cracks is a number on a dial that could be wrong, and the question is not whether you are afraid but whether the fear will reach your hands, because your hands are what fly the airplane, and if the fear reaches your hands you are finished. The hands must continue. The hands know what the mind has lost the confidence to believe. This is not courage. It is training. It is what happens when the body has repeated a set of movements so many times that the movements become autonomous, and the mind can panic or not, it does not matter, the hands will hold the heading and the feet will hold the rudder and the airplane will fly the arithmetic until the arithmetic runs out or the cloud gives way.

At forty-four minutes she broke out of the cloud. The grey wall ended as though cut with a blade, and the air beneath it was golden and still, and the land was below her — real, present, patient as it had always been, waiting at the coordinates the arithmetic had promised. She had been right. The numbers had held. The relief was not an emotion. It was a physical fact, like the sudden warmth of the sunlight on her face after the cold of the cloud, and she accepted it without ceremony, because the alternative to being right had been the escarpment wall at a hundred and thirty feet per second, and there was no ceremony adequate to the distance between those two outcomes.

The Rift Valley was below her.

She had seen it before, many times, and it did not diminish. The valley opened beneath her — enormous, geological, the escarpment walls falling away on either side in shelves of basalt and red soil, the valley floor a hundred miles wide and scattered with volcanoes and lakes and the brown scratch-lines of roads that connected places too small and too remote to appear on any chart she carried. The air below the cloud base was clear and golden, and the late morning light fell across the valley in long parallelograms of brightness and shadow, and the land was ancient and indifferent to the small loud machine crossing it.

She could see the Loita Hills to the east — dark, forested, the Maasai name for them translating to something about a lost child, though she could not remember the exact phrasing. South of the hills, the valley floor dropped further, and there, at the limit of visibility, was a smear of white that could have been cloud shadow or salt flat or, if the arithmetic had held, the alkaline shore of the lake.

She descended to four thousand feet. The engine was running smooth now, the carburetor heat doing its work, the fuel flowing clean. She did not trust it. You relied on an engine the way you relied on your own heartbeat — not with trust, but with the absence of any alternative.

The lake resolved out of the haze — a sheet of caustic water the color of old pewter, rimmed with white, the white being not sand but trona, sodium sesquicarbonate, a mineral crust deposited by the volcanic springs that fed the lake from below. The flamingos were visible from five miles out — a band of pink at the lake’s northern shallows, hundreds of thousands of them, perhaps millions, standing in the alkaline water on their stilt legs, feeding with their heads inverted, their curved bills sifting the algae that grew in water too caustic for anything else to live. From altitude they did not look like birds. They looked like a stain.

And she remembered.

Six months earlier, she had flown to this same camp carrying replacement couplings for the rail spur that connected the soda works to the main Magadi line. The spur was a narrow-gauge track that ran from the camp to a junction three miles south, where the soda ash was loaded onto the Magadi Railway wagons for transport to Mombasa and then to Liverpool and then to wherever soda ash went when it left Africa — glass factories, soap factories, the chemical industries of Europe, which consumed the minerals of this continent the way the lake consumed the flamingos, by a process that was chemical and not malicious and left behind only the residue.

The camp itself was a collection of corrugated iron buildings arranged on the alkaline flat above the lakeshore. There was a processing shed where the trona was crushed and refined. There was a barracks for the African workers — Maasai, mostly, and some Kikuyu — a long, low building with no windows and a tin roof that in the afternoon heat must have been unbearable. There was the overseer’s house, which was larger and had a veranda and a garden in which nothing grew because the soil was salt. And there was the airstrip, which was a cleared stretch of alkaline flat, white as bone, marked at both ends with oil drums painted red.

Grijs had met her at the strip. He was a large man, red-faced, with the particular redness of a European who has been in equatorial sun for years without learning how to live in it — a redness that was not health but a slow cooking, a process of being rendered. He had taken the couplings from her without thanking her, examined them, complained about the gauge, and walked back to the processing shed shouting for his foreman.

She had stayed to refuel. The camp had an aviation fuel store — a single drum of 73-octane, gravity-fed into a hand pump — and while the fuel settled in the tanks she had walked the camp. She had seen the workers. They moved through the soda dust in clothes stiffened white with mineral crust, their skin ashen, their eyes reddened by the alkaline particulate that drifted around the processing shed like a local weather system. One man was washing his hands in a basin of water that was itself white with dissolved soda. He washed and washed, and his hands did not come clean, because the water he was using to wash was the same water that had made them dirty.

Grijs had been shouting at the Maasai foreman. The foreman stood very still, his hands at his sides, his face composed into an expression that was not submission and not defiance but something older than either — the expression of a person enduring weather. Grijs’s Dutch-accented English carried across the flat in the dry air, and the words were about production quotas and railway schedules and the cost of delays, and the foreman said nothing, and Ilsa had stood by the fuel drum and listened and felt the particular shame of a European watching another European perform the cruelty that the colony made possible and that her presence — her airplane, her fuel, her cargo — sustained. She was not apart from it. The soda went to Liverpool. The couplings came from Nairobi. She was the link, the connective tissue of the system, and the system operated whether or not she approved of it, and her disapproval was a private indulgence that the system did not require and did not notice.

The wife had come out onto the veranda and offered tea. Ilsa had sat on a cane chair and drunk it while the wife talked. She talked about the remoteness. She talked about the dust, the heat, the alkaline water that ruined the laundry and stiffened one’s hair and gave the children — she had two, somewhere in the house — a perpetual rash on their shins. She talked about the railway, which was unreliable. She talked about Grijs’s temper, which was worse since they had moved here from the farm outside Nakuru, though she did not call it temper — she called it his way with people, and she said it with the particular resignation of a woman who has replaced understanding with vocabulary. She did not ask Ilsa about the flight. She did not ask what it was like to fly alone across three hundred miles of country in a machine made of wood and fabric. She asked where one could buy decent cotton in Nairobi, and Ilsa told her, and the conversation ended there.

She had walked to the lakeshore.

The calcified flamingos were there, along the waterline. She had not known about them. No one had told her. They stood in rows and clusters on the alkaline flat, white as the trona that preserved them, their bodies hardened into mineral statuary by the water’s chemistry — sodium carbonate at a concentration that could strip the ink from a printed page, a pH above twelve, fed by the volcanic springs whose temperature was near boiling where they rose through the lake bed. The birds that died in the lake or at its margins were claimed by the water. The calcium in their bones reacted with the sodium carbonate and they calcified, slowly, perfectly, the soft tissue hardening into mineral cast, and they remained. Standing. In the posture of their deaths. Wings half-spread or folded, necks curved or straight, beaks open or closed. They did not decay. They did not collapse. They remained, and they would remain for years, for decades, looking in every respect like living flamingos except that they were white instead of pink and they weighed nothing and the wind, when it blew across the flat, moved through them rather than around them because the hollow structures of their bodies offered no resistance.

She had picked one up. It had weighed almost nothing. It was perfect in form. And it was drained of every quality that had made it a flamingo — the warmth, the movement, the blood, the quick heart that beat two hundred times a minute, the brain that navigated by magnetic field and starlight. All gone. The form remained. She had set it down carefully in its place on the alkaline flat and walked back to the airplane and flown home.

She saw the airstrip now, a white scar on the white flat, the red oil drums tiny at this distance, the camp buildings a cluster of metallic glints. She began her descent. The engine held. The fuel gauge showed a quarter tank — enough for the return, barely, if she refueled from the camp’s stores and the wind was kind on the way north.

She flew a circuit over the camp, checking the strip for obstructions — animals, debris, the warthog holes that could catch a wheel and flip a biplane in a cartwheel of fabric and wire. The strip was clear. She turned into wind, throttled back, and brought the Moth down in a long, flat approach, the wheels kissing the alkaline surface and throwing up a plume of white dust that billowed behind her like the wake of a boat, and the tailskid caught and the Moth slowed and she was on the ground and the flight was over.

She cut the engine. The silence was immediate and enormous — the silence of alkaline desert and volcanic rock and a lake so caustic it preserved its dead, and into this silence the ticking of the cooling engine sounded like a clock running down in an empty house.

A figure was walking toward her from the camp — not running, walking — and as it drew closer she saw it was a young Kikuyu man she did not recognize, wearing a white cotton shirt stained with soda dust and carrying himself with the measured urgency of someone who understood that running would not change the timeline. Behind him, on the veranda of the overseer’s house, a woman stood in a cotton dress, one hand shielding her eyes against the glare.

The Kikuyu man reached the airplane. “The serum, memsahib.”

She unstrapped the satchel and handed it to him. His hands were steady. He examined the vials through the canvas, counting them with his fingers, and nodded once.

“How is he?” Ilsa asked.

“The arm is very bad. The swelling has reached the shoulder. We have been applying tourniquets, but —” He shrugged. A medical shrug. The shrug of a man who had done what he could with what he had and was not going to speculate about what he couldn’t. “We will administer it now. Thank you.”

He turned and walked back toward the house, carrying the satchel with both hands, and Ilsa watched him go and thought: his hands were steadier than mine.

The woman on the veranda came down the steps. She was the wife. Ilsa recognized her now — the same woman from six months ago, thinner, more sunburned, the cotton dress hanging on her frame as though it had been fitted for someone with more weight. She walked across the alkaline flat toward the airplane, and her shoes raised small puffs of white dust with each step, and when she reached Ilsa she stopped and looked at the airplane and then at Ilsa and said:

“Thank God. We thought you wouldn’t come.”

She said it to the airplane. Or to the sky. Or to whatever mechanism had produced the result of a serum being present where a serum was needed. She did not look at Ilsa when she said it, or rather, she looked at Ilsa the way one looks at a door through which a doctor enters — not at the door, but past it, at what the door allows.

“The weather was difficult,” Ilsa said.

“Was it? It’s been clear here all morning. Terrible heat, of course. Harold has been in agony. Absolutely in agony. The nearest doctor is in Magadi and the railway is — well, you know what the railway is.” She looked at the airplane again. “Can you stay? In case — if it doesn’t work, can you take him to Nairobi?”

“I need to refuel. I’ll see what’s in the stores.”

“Yes. Good. Good.” The wife was already turning back toward the house. “I should be with him. When they — yes. Thank you. Thank God.”

She walked away. The white dust settled behind her. Ilsa stood beside the airplane and felt the sweat drying on her face in the caustic air. The wife had seen an airplane arrive. If the serum worked, the wife would remember that an airplane arrived. If the serum failed, the wife would remember that an airplane arrived too late. In either case, the story was: an airplane.

She found the fuel store behind the processing shed — the same drum of 73-octane, half empty now, with the same hand pump. She pumped fuel into both wing tanks, working the handle in a steady rhythm, the brass fitting warm under her palm. It took twenty minutes. The fuel smelled of the camp — of soda dust and heated metal and the faint sulfurous tang of the volcanic springs. She pumped and heard the sounds of the place: a generator, a radio crackling with static and fragments of Swahili, voices from the overseer’s house that she could not make out. And beneath all of it the mineral silence of the lake.

When the tanks were full she walked to the lakeshore.

The calcified birds were still there. Of course they were still there. She did not pick one up this time. She stood among them and looked at the living flamingos feeding in the shallows fifty meters out, pink against the white shore, and the dead ones standing in their rows, white against the white shore, and between the living and the dead there was no visible boundary — only the waterline, and the chemistry.

She stood there longer than she needed to. Then she walked back to the airplane.

The flight north was uneventful. This is the word that would go in the logbook, and it would be accurate in the way that logbooks are accurate — recording the absence of incident and leaving unrecorded everything else.

The weather had broken over the escarpment and the sky was clear and she climbed to eight thousand feet and flew by compass and landmark — the Loita Hills, the Ngong, the railway line into Nairobi — and the engine ran smooth and the fuel held and the air was steady and none of it required anything from her except the mechanical attention of a pilot flying a route she knew.

She landed at Wilson Airfield at ten minutes past four. The light was long and amber and the shadows of the parked aircraft stretched across the grass in thin dark lines. She taxied to the apron and cut the engine and sat in the cockpit for a moment in the ticking silence of cooling metal.

Abdi came out of the dispatch hut.

“The delivery?”

“Completed.”

“The weather?”

“Fine.”

He held out the clipboard and she signed the return manifest. He noted the fuel consumption, the flight time, the cargo status. Completed. Delivered. Received. The columns of the ledger filled and the entry closed and the flight became a line in a book.

“Anything else?” he asked.

She almost told him. The missed beats in the cloud. The carburetor heat. The forty-four minutes of dead reckoning over country she could not see, trusting arithmetic that could not be confirmed until it was too late to correct. The wife who said Thank God to the sky. The Kikuyu man whose hands were steadier than hers. The calcified flamingos standing on the lakeshore in the posture of their deaths, white as the trona that preserved them, perfect and hollow.

“Nothing else,” she said.

She tied down the airplane. She secured the control surfaces with their canvas locks. She wiped the alkaline dust from the windscreen with a rag, working in long careful strokes. Two other pilots were sitting in canvas chairs near the dispatch hut, drinking tea, and one of them called out something she didn’t catch and the other laughed.

She walked toward the gate. The light was going.
