Sorry I didn't answer earlier, but the Air Force base in Belleville is Scott Air Force Base. It provides air transportation for Congressional dignitaries as well as Air Evac Medical personnel and air aid for military patients worldwide and also civilians in emergency situations. They also provide air refueling support.
The following page has a video on it about Scott Air Force Base and what it does, what planes are there, etc, if anyone is interested. It might make the playacting a little more real, ya know? hehe
