This seems to be referring only to large international airports. Wikipedia lists 383 airports in the US, only 30 of which are "large". None of the muni airports are on the list. There's so many of those! I can think of 5 within a short drive of my home; there's got to be thousands in the US. So, no shit building big noisy busy things on huge plots of land is hard! NIMBYism scales.
