I did and you link to okcbombing.org doesn't work!
Same results here. Looks like they may have let the domain registration expire -- or there is a DNS problem at their ISP. Last time I checked, the website was being maintained by some guy I never heard of. I'll check with Charles (Key) and the other Board members and see what I can find out.
Thanks for the heads-up!
BTW, I did the section on analysis of the collapse of the MFB. Needless to say, _Jim and I disagree on many points. Most of which deal with believing the FBI's badly-skewed presentation of the evidence -- especially the actual size of the truck-bomb crater.
