I really like 3 green's suggestion of an article from an ATC'ers point of view. As a PPL, I'm sure I'm not alone in never haveing seen the inside of an ATC tower, or a controlers ATC sceen actually working (as apposed to a photo).
So I'd definately second the idea of an article from their point of view. Maybe that one could run as a short series, so as not to be too superficial?
