Windshear, that is wind, can destroy/dissipate a hurricane or tornado. Last time I checked, a building outweighs the wind. How can something "stronger" (building) not perform as well as something "weaker" (wind)? How do you justify this happening?
100%, ALL buildings fail in tornados, each and every time they cross paths, and have done so for five-thousand straight years!! Not one time has a single-use building beat a tornado with 95 mph winds or higher!!
This is 2008, mankind has walked on the moon, drove a car over 600 miles per hour (into the wind), and has submarines that can withstand thousands of pounds of pressure!! Where is the Technology for the buildings, houses, and sheds?
Any opinions on this?
