In this history of international airports, we focus on several airports to illustrate the developments and technology of their construction and operation, beginning with Miami’s Dinner Key and including New York City’s LaGuardia and JFK, London’s Gatwick, Dulles near Washington, D.C., Los Angeles’ LAX, Denver International, Japan’s Kansai, and Korea’s new Inchon. It all began on a farmer’s field near a flat beach–the next step may see them expand into interplanetary platforms!
