The rapid growth of aeronautics since the World War has definitely established the airplane as an important carrier in the transportation system of the country. The greater part of this growth occurred in the latter part of this period. The number of civil craft increased from 2,612 in 1927 to 11,159 in 1938. The number of miles flown by scheduled craft increased from 4 1/4 millions in 1926 to 69 2/3 millions in 1938.
With the growth of scheduled air service and the increase in aircraft, a differentiation or specialization of airports has taken place. In the transport service they now correspond very closely to the types of railroad stations. There are terminals, express stations and local stations; and some airports are like commercial sidings.
The purpose of this Bulletin is to present a reclassification of the airports of the Region to indicate the part that each port should logically take in the present and future operation of aircraft in the Region.
