ABSTRACT
As in so many other areas, the development of aviation during World War II was truly staggering. Aircraft efficiencies had improved out of all knowledge; payloads had increased to the point where the aeroplane could compete economically as a freighter or a carrier of passengers. Additionally, the war had bred an air-minded generation by reason of the great numbers of service personnel which had been flown to and from the various theatres of war. Such circumstances made it certain that once the civil airlines of the world got into their stride, the market for commercial aviation radio equipment and navigational aids would be a big one.
