I'd be interested to know where those wind turbine blades went that it was cheaper to bring them in this way vs. building a road, and the project still made sense with insane transportation costs. A modern 50m class blade costs no more than $500,000, frequently less than $200,000.
The one example I can find was two 42m blades from China to Denmark in 2010. I would think they normally go by ship, so maybe they were in a rush? And if they were shorter, they would use a smaller plane.
