A Maintenance Yardstick for the Designer
THE art of flying has had to develop without benefit of precedents. The business of transportation, however, is of many years standing, and a vast fund of experience is available upon which transport aviation may draw. The type of operation which offers the closest parallel, and which probably can be of the greatest assistance in this regard, is the bus line, for as a transportation unit, the motor bus differs from the airplane only in the way in which it travels.
