Told my husband what you said, and he told me to tell you to notice the difference between the structure of a mushroom and the design of the Superdome. The mushroom has a wide stem at the center "holding" it down.
The Superdome doesn't. I hate to see us "experiment" with this structural design with 20,000 people in it.
Yes, but the mushroom also leaves quite a bit of area exposed for "lift". To me, the 'Dome looks like a hemisphere with a sharp edge halfway up. I really don't see anything for the wind to lift on. But like I said, I'm not nearly qualified to be taken literally or seriously =D
