Nimbus

Barksdale, Louisiana · Friday, April 26, 2047

At 00:27, every light in the room came on at once.

Jaz Coleman opened his eyes into white ceiling panels bright enough to hurt.

For several seconds, nothing connected.

Room.

Light.

Noise.

His heart was already running before his mind understood why.

A repeating electronic tone filled the alert quarters, loud enough to reach through walls and sleep. Jaz stared upward and tried to identify the ceiling. It was not his bedroom. Not home. Not a hotel.

Barksdale.

That solved one problem and created the next.

Why was he awake?

The tone repeated.

Alert.

Jaz sat up.

The movement arrived before the rest of him. His brain seemed to remain somewhere behind his eyes, heavy and slow, trying to reconstruct a world that had existed normally thirty seconds before.

He checked the clock.

00:27.

He had gone to sleep at eleven fifty-something.

“Jesus.”

His feet found the floor.

No exercise announcement followed the alarm.

Jaz stood and immediately had to stop because his balance had not caught up with the decision.

Thirty minutes.

Maybe thirty-five.

He had been asleep just long enough to get properly buried in it.

He pulled on his flight suit, missed the first leg opening, swore, got it right, zipped it, then sat again long enough to drag on his socks and boots. His hands knew where everything was even while the rest of him remained offended by consciousness.

Boot.

Boot.

Phone.

Credential.

Go bag.

He stood again.

This time the room stayed level.

Someone ran past outside.

Jaz opened the door.

The corridor had gone from sleeping quarters to movement. Doors stood open. People emerged fastening flight suits, carrying bags, pulling boots tight as they walked. Nobody shouted. The alarm had already supplied all the urgency the building required.

Emma Hensley came out of a room farther down the hall with her hair pulled back badly and one boot not completely laced.

She looked twenty-three.

Usually she managed not to.

“What is it?” she asked.

“No idea.”

That was all either of them had been given.

Jaz hit the stairwell.

By the time he reached the ground floor, the sleep inertia had begun losing its grip. Not gone. Just pushed behind procedure.

He followed the flow toward the front exit.

Thunder rolled somewhere beyond the building.

The doors opened.

Night air struck him warm and wet.

A service vehicle waited immediately outside, already powered up, warning lights flashing across the pavement. Tessa Vann sat behind the wheel.

Jaz knew Tessa mostly as a name attached to qualifications.

Their regular copilot was home on family medical leave after the birth of a child. Scheduling had filled the seat with Vann.

He had seen her around flight operations. He might have spoken to her twice.

Apparently she woke up faster than he did.

The rear door opened from inside.

“Coleman.”

Jaz climbed in and threw his bag behind the seat.

Emma arrived seconds later.

“Tessa,” Jaz said.

“Jaz.”

That completed their relationship.

Alejandro Cárdenas came out last, moving at a controlled jog with his own bag in one hand. Ali opened the front passenger door and climbed in.

“All here.”

Tessa moved.

The vehicle accelerated away from the alert building.

Lightning flashed behind the clouds.

For an instant, the flight line appeared in pieces.

Wet pavement.

Ramp lights.

Ground equipment.

Then the airplanes.

Old Stratofortress silhouettes lined the flight line under the storm.

Another flash turned fourteen swept-wing shapes black against a white sky.

The sight woke Jaz more effectively than the alarm had.

Routine flying had already been shut down by the weather.

The storm had stopped the work that could wait. Maintenance had pulled crews back from exposed jobs, and the evening proficiency flights had never left the ground.

Now the flight line was moving anyway.

Ground crews crossed between aircraft. Service vehicles flashed through the rain. Access equipment moved. Engines on the far end of the line began turning.

Emergency work changed the acceptable answer to a risk calculation. It did not make thunderstorms harmless.

The worst of the cell remained west of the departure corridor. Tower and weather had a route around it.

The storm had stopped the work that could wait. This could not.

Tessa drove directly toward their aircraft.

Nimbus waited near the middle of the line.

Jaz looked at the familiar outline and felt the last heavy residue of sleep finally begin to clear.

Ali checked the secure display mounted ahead of him.

“Tasking’s in.”

Jaz’s own display populated a second later. He read the tasking, thumbed the acknowledgment, and put the screen away.

“Details?” Emma asked.

“Airborne,” Ali said.

Tessa stopped beside Nimbus.

They were out almost before the vehicle settled.

They reached the belly hatch together. Jaz and Emma stayed on the lower deck while Ali and Tessa climbed past them toward the cockpit.

A maintainer met them at the ladder.

“Aircraft is ready. No open red discrepancies. Weather route loaded. Initial departure package is aboard.”

“Payload?” Jaz asked.

“Green.”

“Anything deferred?”

“Nothing mission-limiting.”

Jaz nodded and climbed aboard.

The lower compartment smelled the way old airplanes always smelled, even after enough modernization to replace almost everything a human hand touched. Fabric. Electronics. Conditioned air. Old insulation somewhere beyond the panels. A faint metallic odor impossible to assign to any one component.

Emma dropped into the navigation station.

Jaz took the other mission station.

Above them, Ali and Tessa began bringing the cockpit alive.

The checklists came through the intercom.

Power.

Systems.

Navigation.

Flight controls.

Communications.

Jaz worked his own sequence.

Mission computer.

Payload interface.

Section status.

Control channels.

Environmental inputs.

Release safeguards.

Another thunderclap reached the airframe as vibration.

“Ground says rapid start approved,” Ali said.

Jaz secured himself.

The first engine came alive with a hard mechanical violence that still felt slightly indecent after all these years.

Then another.

Across the flight line, other Stratofortresses were starting too.

The whole line seemed to wake one airplane at a time.

Emma glanced at the status display.

“Twenty-six is rolling.”

“Good for Twenty-six.”

“Thirty-one right behind them.”

“Then we better not embarrass ourselves.”

Emma smiled.

She had graduated from the Academy into airplanes older than her grandparents.

To her, this was simply aviation.

Jaz remembered when the lower deck had existed for a very different world.

He did not spend much time thinking about that anymore.

“Five-Two-Two-Seven, ground.”

Tessa answered from upstairs.

“Five-Two-Two-Seven.”

“Taxi approved. Follow Five-Two-Three-One. Hold short Runway One-Five. Convective restriction remains west through northwest. Emergency departure corridor active south-southeast.”

“Follow Three-One, hold short One-Five, south-southeast corridor. Five-Two-Two-Seven.”

Nimbus moved.

Rain streaked the small lower windows.

Jaz felt turns more than he saw them.

The aircraft ahead became a moving constellation of lights through darkness and water.

Fourteen aircraft did not launch at once.

They launched as fast as safely became useful.

At 01:21, Nimbus turned onto the runway.

Jaz felt the brakes hold.

Engines rose.

The airframe trembled.

For one moment the airplane seemed impossibly old.

Then the brakes released.

The Stratofortress accelerated.

Runway joints began striking faster beneath them. The sound became continuous. Jaz felt the nose rotate, then the subtle physical release as the tires stopped carrying the machine.

Nimbus climbed into the Louisiana night.

Lightning flashed behind them.

The storm fell away.

Nobody said anything for several minutes beyond required calls.

The fourteen-aircraft package spread south into assigned tracks.

Jaz watched navigation settle.

Emma worked efficiently beside him.

She was new enough to still verify things twice when once would have been enough.

He had no intention of curing her of that too quickly.

At 01:48, Ali came over the intercom.

“Headquarters brief in two.”

Jaz acknowledged.

Emma straightened in her seat.

The secure mission display changed.

A map opened.

The eastern side of Mexico City appeared beneath fire overlays, transportation routes, evacuation sectors and a growing irregular perimeter.

The remote briefer came into their headsets.

“Resilience Wave One, Air Mobility Command. You are responding in support of Mexico City Fire incident command for the Estancia Fire. Fire originated in the Lomas de la Estancia area and has escaped into wildland-urban interface. Local and regional resources are committed. National resource mobilization is in progress.”

The fire perimeter updated.

Orange.

Red.

Projected spread.

Residential polygons.

Jaz opened Nimbus’s payload page.

Seven thousand gallons of water had gone south inside the old Stratofortress.

The briefer continued.

“Your mission is strategic broad-area treatment of unburned and lightly involved wildland-urban-interface exposures identified by local incident command. Direct attack remains with local ground forces and tactical aviation. Your assignment is to reduce ignition probability ahead of the advancing fire.”

Emma looked at the map.

Thousands of roofs sat beneath the projected spread.

She leaned back slightly.

“These machines were built almost a century ago to cross the world and decide whether cities burned. Some things change. Some things don’t.”

Jaz glanced at her.

“That sounded rehearsed.”

“It wasn’t.”

“Worse.”

Emma smiled and went back to the map.

Jaz opened the weather package.

Winds by altitude.

Humidity.

Temperature.

Expected predawn shift.

Surface observations.

Predicted droplet distribution.

Deposition efficiency.

The treatment system began building possible solutions long before it had permission to use one.

“Wave One will establish initial holding south of Mexico City pending final treatment geometry. Wave Two is launching from March and will arrive approximately one hour behind. Acapulco has been activated as the forward reload location.”

A second map opened.

The airfield appeared with servicing areas highlighted.

The support package looked almost embarrassingly simple.

One tanker carried gelling concentrate.

One enclosed trailer carried hoses, fittings, portable pumps, meters, adapters and collapsible tanks.

Local water did the heavy lifting.

The airplane was complicated.

The place filling it did not need to be.

“Treatment polygons will continue updating during transit. Local command is prioritizing residential exposures, evacuation-route surroundings and predicted ember zones. Aviation will calculate final release geometry. Releases automatically inhibit outside certified deposition limits.”

Emma was already moving through the navigation layers.

“Jaz,” Emma said.

“Yeah.”

“I’ve never done houses.”

“I know.”

“My checkrides were forest.”

“I know.”

“And Colorado was forest.”

“Yes.”

She looked again at the screen.

There were thousands of roofs inside the wider incident map.

“This is different.”

“Same physics.”

“That’s not what I meant.”

“I know.”

Jaz pointed at the display.

“Don’t fly the houses. Fly the geometry. Incident command tells us what they need protected. We tell them what we can safely put on the ground.”

Emma nodded.

“And if the answer is no?”

“Then no wins.”

The brief continued another twenty-three minutes.

Shelter movement.

Protected airspace.

Ground acknowledgments.

Utilities.

No-fly zones.

Aircraft sequencing.

Acapulco procedures.

Wave coordination.

By the time the briefer signed off, Jaz had been awake for nearly two hours.

Ali came over intercom.

“Workload’s down. Start rest rotation.”

Ali remained on the controls with Emma covering navigation. Tessa began her controlled rest period upstairs.

Jaz looked at Emma.

“You first.”

She shook her head.

“You were asleep thirty minutes.”

“So were you.”

“I got forty-two.”

“Congratulations. You’re twenty-three.”

“That isn’t how sleep works.”

“It’s how being forty-seven works.”

Emma pointed toward the rest position.

“Evaluator privilege.”

“Abuse of authority.”

“Absolutely.”

Jaz unstrapped.

He crawled into the narrow bunk and lay down still wearing his flight suit.

The airplane vibrated beneath him.

Fourteen old Stratofortresses were flying south.

Somewhere below, almost everyone was asleep.

Jaz closed his eyes.

He did not expect to sleep.

He woke thirty-one minutes later when Emma touched his shoulder.

For one second he had no idea where he was.

Again.

Then the vibration, the pressure against his ears and the dim cabin brought everything back.

“Your turn,” Emma said.

“How long?”

“Thirty-one.”

“Luxury.”

Tessa was back on duty by then. Ali began his own rest period while Emma took Jaz’s place in the bunk. One pilot and one NPO working, one pilot and one NPO resting. The arrangement lasted only as long as the workload allowed.

Jaz slid back into his station.

The fire had grown while he slept.

The aircraft had moved hundreds of kilometers.

The computer had rejected two provisional release geometries and accepted another.

Jaz drank water.

“Status?”

Emma had left him a clean handoff.

He read it.

Tessa’s voice came down from upstairs.

“We’re about forty minutes from initial hold.”

“Copy.”

Jaz checked the latest weather profile.

The wind was becoming friendlier.

Not friendly.

Fire weather did not owe anyone friendly.

But better.

The first final treatment requests began arriving at 04:16.

Mexico City Fire had marked areas it believed could still be saved.

Air Mobility Command translated those requests into something aircraft could use.

Polygon by polygon, the system asked the same questions.

Would enough of the release reach the intended ground?

Would wind shear carry too much of the footprint beyond the approved polygon?

Would evaporation reduce ground coverage below treatment standard?

Was the predicted droplet distribution still inside the certified envelope?

Were aircraft safely separated?

Was the treatment worth doing?

Several proposed areas disappeared.

One shifted east.

Another widened when updated winds improved the predicted footprint.

At 04:42, Nimbus received its first accepted assignment.

Emma was awake again.

Tessa was back in the right seat.

Everyone was working.

Jaz looked at the polygon.

Residential roofs.

Yards.

Interface vegetation.

Streets threading between them.

Beyond that, orange marked the fire.

The release area did not touch the orange.

That was the point.

“Weatherman has treatment,” Jaz said.

Ali answered.

“Aircraft has it.”

Emma confirmed the route.

The system recalculated.

Wind changed slightly.

The footprint moved with it.

“Ground acknowledgment?”

Emma checked.

“Received.”

“Footprint?”

“Contained. Predicted coverage is above minimum.”

Jaz watched the release prediction tighten.

The system was not trying to place a falling mass of water onto a target. It was trying to manufacture precipitation over a piece of ground.

By the time the droplets reached firefighters below, they would be at terminal velocity.

At 04:52, the inhibit cleared.

Jaz placed his hand on the payload controls.

“Treatment armed.”

“Copy armed.”

The city was mostly hidden from his lower station except through sensors and external imagery.

He saw roofs.

Hot spots.

Roads.

A handful of moving vehicles.

Tiny symbols representing firefighters.

The release line approached.

“Thirty seconds.”

Emma read navigation.

“Track good.”

“Wind good.”

“Twenty.”

Nimbus flew over a city that had spent the night moving people out from under a fire.

“Ten.”

Jaz watched the predicted footprint.

“Five.”

The release cue crossed.

Jaz pressed.

The pumps came up. Across the converted belly, oversized sprinkler heads fed controlled streams into the slipstream. Concentrate metered into the moving water at 0.65 percent while the system varied flow among the discharge sections to hold the predicted footprint.

Jaz watched tank quantity fall.

Six thousand.

Five.

Four.

Behind Nimbus, the streams stretched apart and broke into broad precipitation.

The treatment computer painted the developing ground footprint across his display.

Somewhere below, droplets were beginning to fall onto roofs.

Trees.

Turnout coats.

Helmets.

Someone down there might be looking up through the fire glow and city glow, seeing the dark Stratofortress pass overhead without yet connecting it to rain falling out of a cloudless predawn sky.

Two thousand.

One.

The manifolds throttled back section by section.

Flow ended.

Jaz checked residual quantity.

“Payload complete.”

Ali answered.

“Copy.”

Emma looked at the imagery.

The treatment footprint covered the intended polygon.

Not perfectly.

Nothing useful happened perfectly.

But inside tolerance.

Jaz leaned back.

“Welcome to houses.”

Emma stared at the screen.

“That’s a lot of people.”

“That’s why we got up.”

Nimbus turned south.

The eastern horizon had only begun to gray when they reached the coast. The aircraft around them were still mostly silhouettes.

Acapulco appeared ahead.

Nimbus landed at 05:39.

The first turnaround happened largely with the crew still aboard.

Eight minutes later, water was already moving into the aircraft.

Ground crews worked around them while Jaz and Emma stayed aboard. The turnaround checklist moved quickly: water, concentrate, inspection, release system, departure.

They did not fully refuel the aircraft.

They did not need to.

At 06:06, the service connections were coming off.

Five minutes later, Nimbus was airborne again.

The second treatment was less dramatic.

That was good.

Extraordinary things became work quickly when repeated often enough.

They climbed.

Received another polygon.

Adjusted.

Waited.

Daylight overtook them on the northbound leg.

Jaz climbed upstairs during a quiet stretch and looked out past the cockpit. Another Stratofortress was running on a separated track off their left side.

Night had hidden almost everything about it except shape. Morning did not.

The airplane was red. Large white letters ran along the forward fuselage: U.S. RESILIENCE. The tail carried a single word large enough to read across the intervening sky: FIRE.

Another red RF-52 was visible farther away, then a third, all of them moving north toward Mexico City.

The old Stratofortress silhouettes from Barksdale had become something completely different in daylight.

Emma came up behind him.

“Thirty-One?”

Jaz studied the aircraft.

“That’s Thirty-One.”

Emma watched it.

“They really are ugly.”

Jaz looked at her.

“You have no respect for history.”

“I respect history. History is ugly.”

Ali laughed from the left seat.

“Both of you downstairs.”

The second treatment went out at 06:47.

Smoke lay across parts of the city.

The treated areas stood out less from altitude than Jaz expected. Wet roofs did not glow with salvation. There was no line separating safe from doomed.

The treatment changed probability.

That was all.

On the southbound leg, sleep came in scraps.

Emma got nineteen minutes before a call pulled her back.

Tessa slept sitting upright with an efficiency Jaz found almost offensive.

Ali woke her with a hand on her shoulder after they reached Acapulco.

“Where?”

“Acapulco.”

“How long?”

“Twenty-six.”

“Good.”

Jaz looked at her.

“You practice that?”

“What?”

“Being unconscious professionally.”

Tessa unstrapped.

“Three years flying Pacific airlift.”

That was the most personal thing Jaz had learned about her.

On the second return to Acapulco, Jaz finally climbed down during the turnaround.

In full daylight, Nimbus was impossible to mistake for anything else.

RF-52 No. 27.

Nimbus.

Former Air Force serial 60-0024.

A red airplane built from a machine designed in another century for another idea of national survival.

A hose ran into it.

The servicing equipment had spread outward from two trailers into a small temporary utility network across the ramp. Collapsible tanks buffered the local water supply. Portable pumps fed multiple hoses. The concentrate tanker sat off to one side, connected only where needed.

Local firefighters managed all of it. Moving large volumes of water through hose, pumps and temporary tanks was ordinary fire-service work. The trailer carried the adapters.

“That’s it?” Emma asked.

“What’s that?”

“The forward base.”

Jaz pointed.

“Water.”

Then at the tanker.

“Concentrate.”

Then at Nimbus.

“Airplane.”

Emma waited.

Jaz shrugged.

“What else did you want?”

“I don’t know. More.”

“More costs money.”

A firefighter checked the concentrate connection.

Another shut down the water supply after the overfill valve started releasing water onto the pavement.

They did not fully refuel the aircraft.

They did not need to.

Nimbus was airborne again at 07:46.

Once northbound, Ali and Jaz took the next rest pair. Jaz got twenty-two minutes before Emma called him back to the mission station.

The third assignment arrived at 08:13.

Jaz looked at the clock. Their scheduled duty period had ended thirteen minutes earlier. Somewhere back at Barksdale, the relief roster should have reported for work. When that would turn into another crew standing beside Nimbus in Acapulco was somebody else’s logistics problem.

Jaz looked at Emma.

“Your weather.”

She looked back.

“Now?”

“You wanted houses.”

“I said they were different.”

“They are.”

Emma moved into the payload role.

Jaz took navigation.

The switch was ordinary.

That was another advantage of having two NPOs who could do both jobs.

He watched her build the solution.

She worked slower than he would have.

Good.

She rejected the first footprint.

Better.

“Why?” Jaz asked.

“The western edge is too thin.”

“The system calls it acceptable.”

“You asked why I rejected it.”

“I did.”

Emma adjusted the target geometry.

The footprint shifted.

More of the western exposures moved above the preferred treatment density, but the eastern edge lost coverage.

Emma stared at it.

Jaz waited.

“You’re buying the west with the east.”

“I know.”

“Worth it?”

She studied the incident-command priorities again.

“Yes.”

“Then own it.”

Emma nodded.

The release cue approached.

Jaz stayed out of it.

Her hands were steady.

“Treatment armed,” she said.

Ali acknowledged.

Emma released.

The sprinkler manifolds began feeding the slipstream.

Seven thousand gallons became another engineered rain field behind Nimbus.

Jaz watched her watch the numbers.

Not the spectacle.

The numbers.

That was what he wanted.

The pass completed.

“Payload complete,” Emma said.

Jaz checked the footprint.

“Evaluator?”

She looked at him.

“Pass.”

Emma tried not to smile.

Failed.

The fourth sortie began at 09:31.

By then fatigue had become physical.

Jaz’s eyes felt dry.

His shoulders hurt.

Everyone had eaten something, though nobody could remember exactly when.

The aircraft was holding together better than its crew.

That was normal.

The fourth treatment was smaller.

A complicated polygon near threatened structures and vegetation that incident command still believed worth holding.

Then the measured wind profile changed.

The treatment computer withdrew its solution.

They orbited for eleven minutes while fresh observations came up from below and the system worked through new geometries.

Nobody complained.

Seven thousand gallons stayed aboard until the physics agreed.

At 10:07, a new deposition solution validated.

Emma released again.

The aircraft treated another piece of Mexico City that had not burned yet.

Then they turned south.

Jaz leaned his head back against the seat.

“I’m getting too old for this.”

Emma looked at him.

“You said that on the first sortie.”

“I was younger then.”

At 10:49, Acapulco tower cleared Nimbus to land.

As they rolled out, Jaz saw another large aircraft on the field.

RC-17.

The rear ramp was open.

People were coming down carrying bags.

Fresh red flight suits.

Fresh faces.

Relief.

Jaz felt something inside him unclench.

Not excitement.

Permission.

Nimbus taxied to the servicing area.

The replacement crew waited outside the safety boundary.

Jaz knew all four of them.

That alone felt luxurious after spending the night with Tessa Vann.

Nimbus entered another turnaround while the two crews exchanged status.

Jaz handed over the payload condition.

“Water servicing in progress. Concentrate topped after third. No payload discrepancies. Section Four valve lagged once on second sortie, stayed inside tolerance, maintenance has it.”

The incoming NPO nodded and recorded it.

“Weather?”

“Improving for deposition. Fire behavior’s better than it was overnight, but don’t confuse that with good.”

“Polygons?”

“Headquarters will push them. Local command is shifting farther east.”

Emma handed over navigation notes.

Ali and Tessa completed cockpit turnover.

Nobody gave a speech.

Nobody congratulated anybody.

Once servicing and crew turnover were complete, the fresh crew took Nimbus.

Jaz picked up his bag.

For the first time since 00:27, the airplane belonged to someone else’s shift.

He, Ali, Emma and Tessa walked away across the ramp.

Behind them, pumps were already moving water into Nimbus again.

Another RF-52 taxied past in the distance.

Red fuselage.

White lettering.

FIRE on the tail.

The Estancia Fire was still burning.

Jaz checked the transport board.

“Hotel shuttle?”

Ali pointed toward the terminal side of the operations area.

“Eleven thirty-four.”

Jaz checked the time.

11:19.

Fifteen minutes.

Emma groaned.

“I don’t think I can stay awake fifteen minutes.”

Tessa adjusted the strap on her bag.

“You can sleep standing up.”

Jaz looked at her.

“Of course you can.”

They started walking.

A hotel shuttle waited beyond the secure gate.

Air conditioning.

Food.

A shower if Jaz remained conscious long enough to use one.

Then whatever sleep fit inside the rest of their twelve-hour relief cycle.

After that, if Mexico City still needed rain, he would come back.

Behind him, Nimbus was already being prepared for somebody else’s shift.
