> The common solution in many land strapped cities is for airports to rout aircraft over water. That works in costal areas, but not inland. There's no large body of water near the Louisville airport.
The Ohio River is a large body of water fairly close if someone was going to relocate Louisville airport.
Yeah, the terrain around Louisville poses a challenge for placing an airport, but they could do like Cincinnati does, and have their airport located across the river. Or place it between Frankfurt and Louisville. Or do like Pittsburg and make the terrain flat enough for an international airport.
