I like the zeppelin idea, btw.

That is really a good idea indeed!

As the plane seems not to solve the current problem at all. Large blades can already be transported via river barge close to the onshore locations. Or via road, as long as those are wide and straight enough. The problem are the last few kilometres narrow roads through protected forest, along small creeks, up the mountains etc. Alternatively to building a runway in such a remote location, one could also build a wider road. It would impact nature, protection laws and residents in similar ways and completely avoid new problems coming with the plane idea.

A Zeppelin on the other hand could skip the part with a huge runway or wide road completely and just hover over the location and lower the payload, like a helicopter. I have no clue if that is doable from weight, wind influence etc, but the idea seems way smarter than a large aircraft requiring a huge runway.
