Thanks for the clarification. I did a little research into the kind of destruction a dirty bomb could produce, and I found quite a range. I guess, like you said, it depends on many factors including wind, etc... But I agree with you that even a conventional bomb would be a phsycological big strike. I also wonder how the 65,000 fans would react? Many with cell phones (I guess) would get instant info from relatives, etc.. perhaps wrong or distorted info. I could see a panic and stampede. That would not be good.
I calculated 30K deaths at OK; the shrapnel might have killed 100 but the stampede would have been uncontrollable.
So it would look more like a european soccer match?
