Uncle Si gets through security, waits four hours, and then waits some more

Si gets as comfortable as he can in the Uniform's pouch, with only his eyes and the top of his camo hat visible to the outside. A few minutes later, the Uniforms come out of the building and Si gets a little worried upon hearing them talk about the hassles of going through security. He heard a lot about flying and security from listening to the Uniforms when he lived beneath the computer screen, and he begins to wonder whether he should stay hidden or get out and try to find some other way to the plane. Before Uncle Si makes up his mind, a loud voice announces it's time for everyone to go through security. As the Uniform lifts his vest up and over his head and grabs all his other bags, Si knows he will have to stay where he is and hope for the best.

But all Si's worries are for nothing, he quickly realizes. Being made of plastic has its advantages during security checks if you have no metal parts and aren't stuffed with explosive devices or heroin. After a quick ride through an x-ray machine, Uncle Si happily keeps still while the Uniform puts on his vest and grabs all his stuff again and makes his way upstairs to the passenger waiting area.

Once in the waiting area, the Uniform Si is hitchhiking with, and all the other Uniforms and Non-uniforms waiting for the same plane put their gear down in piles of camouflage and green. Soon they all pull out headphones or  books or phones or tablets or go to sleep on the floor. Uncle Si knows from what he's heard that the plane isn't leaving for a long time and his curiosity tells him that now is his chance to do a little exploring. He climbs out of the pouch and comes to another set of stairs leading down and Outside. Above the stairs is a metal beam decorated with stickers that Si climbs up on when he hears someone coming. None of the Uniforms or Non-uniforms see him as they pass beneath. Once he's sure the way is clear, Si jumps off the bean and goes down the stairs as fast as his tiny legs can take him.

Once he gets downstairs and Outside, he realizes he's closer than ever to getting onto an airplane. He wants to run out onto the airfield and climb aboard, but decides against it. He can't imagine what kind of deadly force the Uniforms might use to stop a little plastic man from running up to and boarding one of their planes. After looking for a few minutes, getting more and more excited at the thought of flying soon, Uncle Si thinks it's probably time to get back upstairs. 

Once there, he hangs out for a while in one of the waiting area chairs but quickly realizes that the pouch on the side of the Uniform's vest he came here in, filled with gloves and flashlights and other things, is much more comfortable than the metal seats. Having satisfied, for now, his curiosity, Uncle Si climbs back into the pouch on the side of the vest he came in on and waits. And waits. And waits some more.
