The caller stated that you can have two systems develop at opposites sides of the stadium. When they meet a lighting bolt can occur if charge is opposite. He swore he saw one. I don't have cable and from midnight to 3 am there was not much else to listen too or view besides this thread. Usually too busy.
I wonder if the space enclosed in the stadium is large enough for coriolis forces to have an effect on the air inside. If they gather everyone in the center and their body heat rises fast enough, they could actually get a little hurricane going inside.

That's why I never wear tinfoil over my head in domes... Don't want to be a lightning magnet...};^b)
