A couple of months ago (I'm cleaning out bookmarks) James Fallows wrote about How Air-Traffic Controllers Sound When They Have to Close the Airport.
"Why do I mention this? One reason is that real-time responses to crisis are just plain interesting—and you can enjoy the drama with clear conscience in a case like this, in which (apparently) no one was hurt. But the major reason is to emphasize a point that my wife Deb wrote about here, and that most air travelers never get a chance to witness. That is the remarkable unflappability of air-traffic controllers in circumstances that would leave most people very flapped."
