Airport

At the airport, they use an x-ray machine to see the inside of people's stomachs. People come up to the booth and are approved or denied based on their paperwork.

1. Check if the people inside match (by face, gender, etc)
2. Check number of declared meals inside
3. Check for the 'turducken'
4. No metal allowed inside.
   1. If an occupant has i.e. piercings, a stomach diver needs to go in for a cavity search
   2. Generally the diver is watched to ensure they make it out, but a distraction means they might go for a full tour

Flyers need to pay for a ticket extension for each passenger who makes it through the end of the flight. So try to digest before the flight is over.
