I have a lot of respect for the controllers at busy airports. The level of stress is, as you know, very high.Yup, that's what they do. I used to take my flight students over there to experience the RAPCON and Control Tower. In those days you could walk right in and get a tour of the facilities any time, day or night.
The facility chief got in trouble frequently with his Air Traffic Service superiors because he didn't meet his quota of FAR violation write-ups against pilots, and because he had so many controllers on staff who were licensed pilots, a combination that died-in-the-wool controllers are inherently suspicious of. It took them awhile to realize that BTV actually had a lower than usual violation rate, and that it was due largely to his (and his controllers) pilot education efforts, and his low-sress management style.
