According to USA Today:
One of the USA’s newest airports has a 5,500-foot lighted runway, a Colonial-style terminal with white columns, and hundreds of acres for growth. But Kentucky’s Williamsburg-Whitley County Airport lacks one feature: airline passengers.
Built using $11 million in federal money, the airport is used only by private airplanes. Many are piston-engine aircraft owned by residents such as Keith Brashear, the airport board chairman who keeps his two-seat Cessna in the airport hangar. On a typical day, the airport has just two or three flights, manager Jessica Roberts says. Some days, there are none.
