Then again just because you can just barely get off the ground when the wind conditions are just right doesn't mean you have airplanes either. For TL purposes you don't measure from the first sort of successful prototypes but from when general implementation happens. In the case of airplanes, that's basically World War I. And it's TL 6 where the railroads were TL 5.
