It is well known in most circles that airlines travel on highways in the sky. Admittedly, most folks don’t know those highways are called airways, but the name is logical, whether the general public knows it or not.
However, few have made the obvious connection between the highway in the sky concept, and the airport in their town. Perhaps this is because aircraft, unlike automobiles, can choose to use the highway or go off-road (VFR) at will. And unlike automobile users, there are massive numbers of pilots flying off-road (VFR) every day, from coast to coast.
