Wow, thanks for posting. That really shades what they're going for differently, much more ambitious than I'd first thought.
So this will be bigger than 10MW that Vesta. Blades will almost certainly have to be >35t. For compare the largest turbine now is China's 16MW turbine (note that a couple m of the diameter is in the hub not the blades, but still):
> Goldwind’s GWH252-16MW intelligent wind turbine has a rotor diameter of 252 meters (827 feet)
Thanks, missed that detail. So the plane, when it becomes available, would be almost long enough for blades deployed off-shore today. (e.g. Siemens-Gamesa SG 14, 108m and 115m)
