An introduction of the Dornier Wal in japanese

The Dornier Wal flying boat has been the forgotten "roaring" seabird of the sky and the sea from the Twenties and the Thirties of the last century. Designed by the aeronautical pioneer Claude Dornier, the Dornier Wal was constructed in Marina di Pisa (Tuscany) from 1922 onwards and constructed under license a.o. by Kawasaki in Japan (1924). The Dornier Wal won worldwide acclaim because of the pioneer flights of Roald Amundsen, Ramon Franco, Wolfgang von Gronau and many others. In Europe and Germany in particular the Dornier Wal was forgotten when the big Wal, the Do-X, came on the scene (1929). The worldwide history of the Dornier Wal is much more interesting because the Dornier Wal, being a flying boat, brought aviation to the most remote places of this  blue planet. In Claude Dornier's own words "the Wal made Dornier". In the book "Dornier Wal a Light coming over the Sea" the great adventures of the men and their more than 300 flying boats in operation all over the world are described. No other German designed aircraft has had a greater impact on the development of international aviation. In Latin America the Dornier Wal stood at the cradle of civil aviation and served the famous Air Mail Service to South America managed by the Luft Hansa, later Lufthansa, with spectacular catapult ships from the year 1934 until the eve of the Second World War.
