What makes the super dome so safe? I wouldn't be in there, no way. They said there are new buildings that weren't there back when they tested it before for wind speeds.
It's the biggest and best facility they have, but I have not heard anyone promise it's safe. They just "don't know."
Engineer's hubris. You know, like the Space Shuttle and WTC. No, seriously, the Superdome is not below sea level so it should be relatively safe from flooding. Honestly, they're guessing whether it'll be sufficient. There is a reason it is *not* being called a "shelter" by the officials but rather a "destination of last resort." They're very careful about that.
Supposedly the roofing has been replaced (the panels, not the coating) recently. There are outdated wind data profiles but since they don't exactly have time to dream up an alternative.
