The Belly of the Beast?

Everytime I fly in or out of Paris' Charles de Gaulle (CDG) airport - terminal 1 - I always get the feeling I'm in the belly of the beast. First stage is the trip through the intestines - the long, whitish, moving sidewalk ride from the terminal out to the gates - as seen below:


Then, when you arrive back home you reverse the course, go through the intestines once again and into the blood vessels - the long, clear tubes that transport you from the terminal to the baggage claim area and finally out onto the street...


Crazy imagery but that's the way it comes across to me...
