A US company is building the world's largest aircraft without having ever built a plane before.
The WindRunner is being constructed to transport large wind turbines and will be operating by the end of this decade.
It's eight times as big as the largest military aircraft, with a cockpit as tall as a five storey building.
Radia CEO Mark Lundstrom told Ryan Bridge it's capable of moving gigantic things to hard to reach places, including for humanitarian missions and defence applications
He says the goal is to move a more than 100metre long turbine blade and land it on a piece of dirt within confines of a wind farm, which would reduce cost of wind energy by a third.
