Awesome is the only word that comes to mind. I just finished watching a "special" on the grounding of all air traffic on 911. Kudos to those air traffic controllers, talk about flying by the seat of your pants. They had over 4000 planes, on the ground, in less than 3 hours, amazing. The FAA met afterwards to formulate a plan with written guidelines, if something like this were to take place again, and they finally arrived at the conclusion, there is no way to write down any guidelines. A lot of hero's on that day, that were back to work like nothing happened the next day. Of course, there were 3000, that weren't back to work the next day, of course THAT is another story.
