"plane" by Chris Lewis

The release number is 1. The story creation year is 2009. The story headline is "Plane: A Tale of Pride". The story genre is "Medieval Morality". The story description is "A story about love at 30 000 feet.". Use no scoring.

The Cabin is a room. "The cabin is a long thin corridor surrounding you, bright light piercing the tin can that is propelling you at 600 mph through the lower atmosphere. A putrid smell of various processed food stuffs mixes with the thin air. People in various states of personal detachment are to your left and right. Some are sleeping, some are watching 'Beverly Hills Chihuahua'. They are essentially zombies.

You wonder if zombies actually come alive on aeroplanes. Then they could be immortal humans, doomed to be locked in on an eternal long-haul flight. You ponder this possibility for some time.

To the south are the bathrooms.
