Well, it adds to the realism and helps with taking good screenshots. 8-)
Also, with some of the people and stuff, you'd have to figure out some way to map the airport to the animations so that they don't end up walking through walls, mountains and trying to take other people's airplanes!

Superhumans!!!

Plus, it shows dedication and ability, even if they couldn't add the complete animations. I put many things into my repaints that I doubt even show up they're so small, and if they do, I wouldn't be able to tell you where half of them are. It's just a nice thing you can do. It's kind of like saying with school, "why get a D or higher when I can pass on a D-?". And yes, for the school grades, here in America, you can.
Last time I checked, i'm pretty sure that was a giant particle accellerator/collider. I've seen it and read about it before.
