"Six Amazon.com Inc (AMZN.O) workers were confirmed dead on Saturday after a series of tornadoes roared through a warehouse near St Louis, ripping off its roof and causing 11-inch thick concrete walls longer than football fields to collapse on themselves." Horrific. A wall that size cannot possibly survive a big wind. Cannot.

A reinforced concrete should've been easily capable of withstanding a hurricane.
First thing I see is that roof was not attached to anything reinforcing in the wall, or columns.
It seems it solely relied on its weight, which was easily overwhelmed by wind, to keep it in place.
