Chapter 19 - The Machine in the Tunnel

The floor began vibrating.

Dust fell from the ceiling as the red signal moved closer to the hidden laboratory.

Martin ordered the officers to guard the passage.

Victor stared at the airport map.

“That tunnel was sealed years ago.”

“Not sealed,” Ethan said. “Converted.”

The vibration became louder.

A low mechanical roar echoed behind the walls.

Samuel’s voice came through the vault speaker.

“Vincent built an automated transport unit. It carries equipment between the old storage facilities.”

“What kind of equipment?” Martin asked.

Samuel hesitated.

“Engines.”

The officers exchanged uneasy looks.

The tunnel was large enough to move complete aircraft engines beneath the airport without appearing on official cargo records.

Vincent had been replacing defective components underground, beyond the reach of cameras and customs inspections.

The steel door at the far end of the passage buckled inward.

Something massive struck it again.

Victor pointed toward the transfer control.

“That option may redirect the airport network into the transport system.”

Ethan understood.

If he transferred control, Vincent’s software would be trapped inside the underground machine network. The airport’s main systems would be released.

But the transport unit would then receive every hidden command at once.

No one knew what it would do.

The pressure inside Samuel’s vault continued rising.

Ethan turned the mechanical linkage to TRANSFER.

Nothing happened.

“It needs authorization,” Victor said.

“Whose?”

“Project 417 required three original members.”

Martin looked toward Victor.

“Samuel, you, and me.”

Victor placed his hand on the first pressure plate.

Martin placed his hand on the second.

The third was inside the sealed vault.

Samuel could not reach it.

Ethan examined the circuit.

“The third plate only measures resistance.”

He removed a copper wire from his toolbox and connected it to the panel.

Victor stared at him.

“That could overload the system.”

“It only needs to believe someone is touching it.”

Ethan completed the connection.

All three indicators turned green.

The transfer began.

Across the airport, compromised screens shut down. Security cameras restarted. Badge readers reset. Aircraft guidance systems returned to manual control.

Inside the tunnel, the approaching machine screamed.

Its motor accelerated beyond safe limits.

Vincent’s face disappeared from the monitors.

The steel passage door exploded inward.

A giant transport platform burst into the laboratory, carrying a dismantled jet engine strapped to its frame.

The machine struck the wall and stopped only feet from Ethan.

For several seconds, no one moved.

Then the straps around the engine snapped.

The turbine rolled sideways and crashed through the control console.

Sparks filled the room.

The vault pressure began falling.

Samuel’s door unlocked.

Ethan ran toward it as the steel barrier slowly opened.

A tall figure stood inside the smoke.

His face was scarred, and one leg was supported by a metal brace, but Ethan recognized him immediately.

“Dad?”

Samuel Hale stepped forward.

Before he could answer, Victor pointed toward the damaged transport platform.

A hidden compartment beneath the engine had opened during the crash.

Inside were dozens of passports, encrypted drives, and employee records.

On top lay a photograph taken only two days earlier.

It showed Vincent Lang standing beside Airport Director Harold Crane.

And between them stood someone Ethan had never seen before.

A woman holding the original Project 417 file.
