The hangar was quiet, save for the rhythmic clicking of a cooling engine. Elias, a veteran propulsion engineer, stood before the exposed core of a CFM56. To the untrained eye, it was a mess of alloy and plumbing; to him, it was a choreographed masterpiece of thermodynamics. "It’s just a continuous explosion, isn't it?"

"Exactly. We spray fuel into that high-pressure air and light it. It doesn’t explode like a car engine; it burns steadily. That expanding fire has nowhere to go but back, screaming through the ."

He stepped back, looking at the sleek housing. "Suck, squeeze, bang, blow. We’ve been doing it since Whittle and Ohain, but every time one of these wakes up and shakes the tarmac, it feels like we’re cheating physics just a little bit."

Elias gestured to the rear, where the most advanced alloys lived. "The turbine is the 'price of admission.' It steals just enough energy from the hot exhaust to keep the compressor spinning at the front. The rest of that energy? It blasts out the nozzle."

He pointed to the . "It starts here. The engine takes in a massive gulp of air. The fan does most of the heavy lifting, pushing air around the core for thrust and cooling. But the air that goes inside ? That’s where the magic happens."

Maya looked at the engine with new eyes. "It’s not just a machine. It’s a storm in a bottle."
