A worldwide scheduled air transportation system for passengers, cargo, and mail has been created since World War II. In its global scope it is almost unique; the International Air Transport Association's only prototype is the Universal Postal Union, which for over a century has been the intergovernment vehicle for arranging the expeditious, reliable interchange of foreign mails between nations. Somewhat comparable to IATA in purpose but much more limited geographically, are such arrangements as those which provide for the transfer of electric power across the border between the United States and Canada, the coordination of highway, waterway, and railway traffic respectively in Europe, and the international telephone, cable, and radio services. The general public does not know—and has little need to know—what has gone on behind the scenes to create these facilities which in essence are large international public utility systems. A typical person's impressions would probably reflect his nationality. An American would probably assume that the individual components of such a utility system were privately owned and operated for commercial profit (except for the Postal Service). A European would tend to assume that electric power companies, railroads, airlines, telecommunications companies, and the Postal Service would all be owned by some government. Each would be substantially correct in his own context.
