The author's an idiot who felt the need to shoehorn the recent hurricane prediction into the story of a product that is clearly designed for tornado alley.
Likewise, I thought those that lived in tornado alley had below ground shelters.
I saw a news piece a while back about a professor that built an air gun that could shoot 2x4s at ~225mph. For the purpose of
testing what it would take to build a tornado resistant shelter at minimal cost. But that was with reinforced
concrete or brick.
BTW, what's the useful life of kevlar? Doesn't it lose its effectiveness?
