Nearly 3.5 million people have watched a YouTube video showing a massive May tornado rip through southwest Iowa, shredding and felling giant wind turbines in its path. That storm damaged hundreds of homes and killed four people in Greenfield and one person near Corning. One of nine tornadoes that day, it had winds over 185 mph — and possibly over 300 mph, according to a research team's mobile radar readings. MidAmerican Energy says it has been working to remove six damaged turbines it owns in Adair County that likely received direct hits from the tornado. Four other damaged turbines in nearby Adams County are owned by RPM Access, which did not respond to requests for comment. Tap the link in our bio for more on this story. #Iowa #tornado #windturbine
