Airports too small?
Seven Stroke Roll opines that "airplanes get too big, or airports get too small, which is easier to change?"....... The answer is not necessarily obvious.
I recollect from reading aviation history that a British Aircraft manufacturer, shortly after WWII, decided to go with making planes (for those who could afford this luxury way of travel) that were capable of landing on the existing short runways. But other companies went for long haul capacity craft that could carry a lot of bums on seats. And guess what happened?
Every major city built a bigger airport.
