A blade has broken off a wind turbine near Dornstadt in the Alb-Donau district of Baden-Württemberg. The part, which weighed around 15 tons and was 40 meters long, crashed into a field near the Autobahn 8 freeway and a railroad line on Thursday afternoon, the police said. There was a risk that parts could be blown onto the tracks around 250 meters away and the roadway behind due to the strong wind.
