I agree, which is why the Wright Brothers less "invented flight" than "had the first sustained engine-powered flight." A lot of historical documents describe it similarly to the latter, but that doesn't quite roll off the tongue. I think there's a loose threshold for when something is "viable," and that becomes the genesis of invention. Even in the Wright Brothers' case, the first flight was viable only in demonstration, there was no practical application for a few generations of aircraft. And as this article highlights, US hegemony kind of ruled via the "winners write history" theory. Which is why some people still say Edison invented the light bulb.
