If you'd like to hear more about Newt Gingrich's plan to "reform" air-traffic control from someone who really knows the subject, I heartily recommend
this entry from Don Brown's generally admirable
Get the Flick site. Brown is a retired air-traffic controller with a knack for explaining technical matters clearly - and with an attitude, which makes reading his accounts fun. I think he is closer to Andrew Sullivan's original
mockery of Newt than to my more
respectful reference. In any case, definitely worth considering if you care about the topic.
