Offshore wind power projects set up shop in the water because it’s often too much of a logistical nightmare to transport their massive turbine blades inland. But that could change in the future if one startup is successful in building the world’s largest plane.

According to the U.S. Department of Energy, offshore wind turbines can be as much as one-and-a-half times the height of the Washington Monument and feature blades the length of a football field. That’s specifically why Mark Lundstrom, an aerospace engineer, and his company, Radia, is building the WindRunner, a massive plane that’s also the length of a football field. If completed, the WindRunner will be the largest plane in the world in terms of length and cargo capacity.
