Good catch. I didn't notice the date.
Still, a good article and I really wonder if anything is changed. Controllers in major US centres work in a really intense environment and I was always impressed with them whenever I operated into places like O'hare or La Guardia. You really had to pay attention because things happened fast and they didn't have time to lead you around by the nose and repeat stuff. It's too bad such highly motivated people often have to work in such toxic environments.
