Hello Life;
You can go to
www.NATCA.net and look at our website that will give you some insight as to what controllers do. There are quite a few things on the site. You can also contact the National Office of the National Air Traffic Controllers Association if you need any further info, the address's and phone numbers are on the web site. If you need anything else, let me know.
