My job exposes me to a fair amount of classified information. This will increase dramatically next year when we begin Spiral Two of our project, involving much more classified information. In addition, I worked with a lot of classified info when I was active duty in the Air Force. Sometimes, I have to be careful about what I write or say because it's easy to forget what is and what isn't sensitive. A lot of the stuff I work with is unclassified but For Official Use Only (FOUO), meaning I can't discuss it here, either. I'm not saying this to sound like something I'm not, just that there are things I can't or better not discuss lest I lose my clearance, my job, and perhaps more. Better to be circumspect than fired.

Those of us who work in the industry have to be mindful of Kim Keller's experience. He was a pad rat for the Shuttle and used to post on the MSNBC web site regularily. He also had a small web site of his own that he posted Shuttle pictures. For that, he was fired because his employer said he was revealing too much information. I hear he's working for another aerospace company now, but I have not heard from him for a long time.

I also agree about keeping the crackpot filter up to date. Odds are we're going to see a lot more of them in the coming weeks.
