Having lived through several tornadoes I can assure that they invoke raw primal fear deep in your soul. I imagine being Blitzed during WWII had a similar psychological effect. That feeling of needing tongs & a shoehorn to pry your nuts out of your throat afterwards is not easily forgotten.
I passed through Moore, OK in 2013 right after they had the infamous EF5 tornado in May. It was like travelling through the Ruhr Pocket in the Spring of '45. Unbelievable damage.
