I know there's a movie (and I think it's a comedy) about air traffic controllers called Pushing Tin. I went with Bill Schumann, FAA Public Affairs, to take some shots of a working air traffic control tower at Dulles International Airport for a text book. I was happy with the photos I took in the approximate half-hour I had to shoot. One of the things I remembered while I was there ... air traffic controllers traditionally dress casually. I remember the air traffic controllers at Marine Corps Air Station New River, NC. The guys in the ATC tower usually worked in their skivvy shirt to be more comfortable. I remember the last Friday of every month they had the option to wear civilian clothes if they put $4 toward the unit's picnic.
