For what it's worth, I just talked to my brother-in-law, a structural engineer.
I asked him about the Superdome. He says all bets are off above 175MPH, without exact blueprints and technical data. Maybe it won't get that strong. Here's hoping, prayers up.

Alarm Rider, my architect husband agrres with your structural engineer brother-in-law completely! These guys know enough about structures to not venture any guesses without detailed information about how the thing is actually put together.
My hu8sb and says this, however. If he were forced into the Superdome as a last resort, he wouldn't go into the seating or arena, but would try to stay near the exterior walls in the concession areas...
