you need a monolithic dome with a minimal amount of windows

Unfortunately not in many parts of Texas.  Water table is too low.  



 

I would have to think they would do fairly well. It would be interesting to see how they hold up.



 

That demonstration was done at a State Fair for purely illustrative purposes, not as a bonefied test procedure.



If you look into the testing criteria at Texas Tech, you will see that their lab has the equipment to hit the subject shelters with debris moving at close to 300mph.



It would take an EF-5 tornado to throw a car at anywhere near 200 mph. I've seen film of the EF-5 which hit OK City a few years back, where you can clearly see pickups and semi-trailers flying around in the debris cloud. An EF-5 'scours' everything above ground level. Thankfully, EF-5 tornados are about as plentiful as siamese twins.....they happen....but not very often.



Again, like I said before, I'd rather be underground......

This basically would have involved us going north and finding a place to hang out all day.

This came over my office on Saturday while I was at work. There was some rotation to it.  I told my Dad we needed to GTFO and go to my house about 10 miles south. It was on it's way to Forney when I took this.

Look at any situation and youll see that most people are unprepared for it. Tornadoes included.

As I said earlier in my post, even when I talked to the wife about getting one she said "they seem kinda old fashioned". She grew up in the suburbs all her life but we life in a small community now. Id say a good number of people in rural areas still consider them a necessity. People in the city have a completley different mindset. A "that only happens to other people" mindset. Hence the reason they are pretty much non-existant in densley populated areas.
