Not surprising the ATC guys seemed to have it together. They are trained to handle stressful situations and employ concise telecommunications.
I was shocked how bad the NORAD NEADS came across, particularly the ID Techs. Referring to a real world hijacking as "cool" and taking 15 words to get across information that should take 3 words. I'm not criticizing the individuals because it was a stressful situation for anyone to handle, but I am critical of their training at the time. I would have thought they would be better prepared. Hopefully they are now.
