While business aviation is an industry built around commerce, Dr. John Kasarda at the University of North Carolina envisions entire cities built around what he considers the center of commerce in the 21st Century: the airport. Kasarda explores this idea his new book, Aerotropolis. He suggests that today businesses are as connected across the globe as they are across the street. For that reason, the Aerotropolis, a city with an airport as its focal point, is central to competing in a global economy.
