A southeast Iowa factory marked a major milestone Thursday.
The Siemens plant in Fort Madison celebrated making its 10,000th wind turbine blade.
Plant employees shared a celebratory lunch Thursday afternoon to mark this production milestone.
The first blades the Fort Madison facility made back in 2007 were 49 yards long.
That is almost half the length of a football field.
The blades it produces now are 60 yards long.
They weigh an incredible 10 tons each.
The Siemens plant in Fort Madison produces wind blades for customers in the U.S.A., Canada, Chile, Peru and Brazil.
They say the giant blades are shipped by truck and rail.
