Fifty years ago Charles Lindbergh made his flight across the North Atlantic, and Juan T. Trippe launched the first international scheduled air service under the United States flag. Lindbergh‘s goal was to translate aviation technology into economic airplanes that could offer low fares. One of Trippe‘s contributions was helping to create the economy class. Seawall focuses on the U.S.-flag system, which comprises the U.S.-flag airlines that operate overseas. They enrich lives, restrain inflation, create jobs, and contribute to the growth of international tourism. Airlines resist increases in the cost of living by developing a mass market, operating efficiently, and applying new technology. The existence of the airlines is threatened, because the regulation of the industry does not permit most airlines to earn enough to replace their aging and obsolete airplanes. Seawall indicates what should be done to continue the national benefits that the airline industry confers. Addressing chiefly international air transportation, he proposes as an objective establishing a U.S.-flag system that improves aeronautical technology and the economics of air transportation, and encourages further growth in tourism.
