The seaplane line "Blaue Linie" (blue line in English) was a short-lived line for passenger- and mail transport that operated from 1925 to 1926 along the river Elbe and was operated by the Junkers F13 seaplanes. It connected the cities Altona (today part of Hamburg), Magdeburg and Dresden. Winter weather and the growing competition from land based airplanes made this line a brief adventure.
Because of the lack of seaplane bases and the reality of seaborne aviation in the early days I have decided to bring a very basic package for those who want to indulge in the seaplane aviation of that time. To make this addon compatible and for lack of sources how the seaplane bases have looked at that time I have only put some standard buildings. So basically this pack adds 3 water runways with parking docks so you can start from cold and dark.
I have found the aerial overview style in a document called "Flughandbuch für das Deutsche Reich" which documents the situation and equipment of a number of German airfields as there were in 1932. So for those who still look for source material on other airports, that is the way to go.
