In reference to my post about the TSA website, I'd like to pass on a list being updated by an energetic soul over at FlyerTalk forums of the status of airports and scanners. Please note that airports that are listed without scanners are still not guaranteed to be safe, but that all of the airports listed with scanners are accurate.
If you have any first-hand info about airports, please contact the maintainer of that thread, or put a comment here and I'll contact the maintainer.
I'm reprinting the current list here:
