System failure imminent. All flight controls compromised. The automated voice cuts through the Boeing 777 cabin like a scythe. Emergency lighting flickers to life. Red warning signals flash across every seat-back screen. Two hundred passengers freeze mid-conversation, mid-bite, mid-breath.

In seat 1A, Blake Morrison pauses with his champagne glass halfway to his lips. The crystal trembles in his manicured hand. Around him, the first-class cabin erupts into chaos. Someone screams.
A child starts crying. Flight attendants rush past with urgent whispers. Blake has no idea the woman he humiliated 20 minutes ago is the only person who can save this flight. He has no idea she controls every line of code keeping them airborne. He has no idea that in exactly 14 minutes, he'll discover that stealing her seat was the mistake that grounded more than just his flight.
The main cabin lights flicker off completely. Emergency strips along the floor illuminate like a runway. Passengers grip their armrests. The plane's engines change pitch, that subtle whine that makes even frequent flyers nervous. Ladies and gentlemen, this is Captain Carlos Mendoza speaking.
His voice crackles over the intercom, strained but professional. We're experiencing a minor technical issue with our navigation equipment. Please remain seated with your seat belts fastened while we troubleshoot. Minor technical issue. That's pilot speak for we have no idea what's happening.
In seat 34B, Victoria Hayes continues typing on her tablet. Her fingers move across the screen with surgical precision. While everyone else panics, she remains perfectly calm. Her dark eyes reflect the tablet's blue glow. She's writing code.
Complex, beautiful, devastating code. Blake Morrison stands up despite the seat belt announcement. His six-foot frame towers over the first class cabin. This is unacceptable, he announces to no one in particular. I have a board meeting in London tomorrow morning.
This better not delay my connection. A woman in 2C clutches her husband's arm. Are we going to crash? Of course not. Blake scoffs.
He adjusts his Italian silk tie. These planes practically fly themselves. It's probably just a computer glitch. If only he knew how right he was. Ashley Palmer, the lead flight attendant, rushes past him carrying a satellite phone.
Her blonde hair has escaped its perfect bun. Sweat beads on her forehead despite the cabin's air conditioning. Ms. Palmer Blake calls out. I need to know exactly how long this delay will be. Sir, please return to your seat.
