A secure communications terminal appeared beside the air compressor.
Three monitors sat on a steel table normally used for rebuilding carburetors.
Encrypted hardware shared a power strip with Isaac’s welding charger until a logistics technician nearly had a heart attack and installed dedicated service.
Dale Hutchins watched it happen from across the fence.
By the second day, he stopped sending employees outside to laugh.
The people arriving at Isaac’s garage wore government badges.
Engineers.
Security staff.
Technical specialists.
A portable antenna rose above the lot.
Nobody told Harlow what was happening.
Harlow invented its own explanations.
Someone at the diner said Isaac was fixing a military drone.
Someone else said missile.
Raymond Ellis said those people were idiots and kept drinking coffee.
Adrian Cole worked directly beside Isaac.
At first, he approached the arrangement with disciplined neutrality.
Isaac noticed.
“You can say it.”
Adrian looked up.
“Say what?”
“You’re wondering why they brought you to a garage.”
Adrian hesitated.
“Yes.”
“Reasonable.”
“I read your report.”
“Three times.”
“How do you know?”
“You printed it double-sided but page nineteen was upside down.”
Adrian stared.
Isaac continued.
“You kept rotating the stack.”
Adrian looked almost embarrassed.
“You notice too much.”
“That helps.”
Their first disagreement came over simulation methodology.
Adrian wanted to build the full digital model.
Isaac wanted to isolate the resonance mode first.
“We have access to a twelve-million-variable vehicle model,” Adrian said.
“Good.”
“Then why are we reducing it to six degrees of freedom?”
“Because only six matter.”
“You don’t know that.”
“Neither do you.”
“That’s why the full model exists.”
Isaac looked at him.
“How long does it take to run?”
“About six hours per case.”
“How many cases?”
“Probably eighty.”
“How many days?”
Adrian stopped.
Isaac pointed at the whiteboard.
“The satellite does not care how elegant your simulation is.”
“Build the small model.”
“If it fails, expand.”
Adrian reluctantly agreed.
The small model ran in seventeen minutes.
It reproduced the thirty-one-minute harmonic.
Adrian looked at the screen.
Then at Isaac.
“Okay.”
Isaac nodded.
“What?”
“You were right.”
“That happens.”
Adrian laughed.
For the first time.
By the third day, he had stopped seeing the garage.
He saw the work.
Isaac could read telemetry the way some musicians read scores.
Tiny phase shifts meant something.
Noise floors meant something.
A pressure recovery curve that appeared nearly identical from one orbit to the next would make him stop and point to a slope difference no one else had noticed.
He did not perform intelligence.
That unsettled Adrian at first.
Brilliant people in academic environments often signaled brilliance constantly.
Isaac behaved as though being correct was merely another tool on the wall.
When wrong, he crossed out the equation.
When uncertain, he said:
“I don’t know.”
Adrian came to respect those words almost more than his answers.
On the fourth afternoon, Isaac drew a correction function on the back of an AutoZone receipt.
Adrian stared.
“What is that?”
“Command compensation.”
“For the regulator?”
“Initial approximation.”
Adrian read it.
“You derived this from the reduced model?”
“Yes.”
“On a receipt?”
“Paper’s paper.”
Adrian photographed it and sent it to Houston.
Twelve minutes later, Grace replied.
WHO DERIVED THIS?
Adrian typed:
THE MECHANIC.
Grace responded:
