Is that good hdxpdex? LOL. Greg, I will have to find that book you are talking about and read it. It will be interesting to compare it to all the classified documents I read on the subject and what I learned talking with some of the participants. I did read a book by the name of the "Puzzle Palace". It was about the NSA where I worked for the better part of 20 years. It was kinda funny. I was still working there when I read it. A bit of fact, a lot of conjecture and a whole lot of bull. We all had a good laugh at work over it. In reality, some of the stuff in "The Hunt for Red October" was more accurate than the so-called tell all book. I still would like to know where Tom Clancey got some of his info. It was highly classified at the time and just so happened that I had to work that problem from time to time. That made for a REALLY good read. Layoutshooter
