Hi Puck,
>Four digit inflation, carry your lunch money in a bushel basket kind of financial trouble?
You're thinking of the 1923 Hyper Inflation which was caused by the German attempt to stop reparation payments. The 1930s' problems were the result of the Great Depression and resulted from excessive industrial capacity, with the situation in Germany made worse by inappropriate gouvernment measures.
I'm not quite sure about the aviation industry as it was almost completely state-financed (considering that the Deutsche Luft Hansa was state-owned, too), often based on cost-plus contracts (with the Reichswehr constantly complaining about cost). The situation had been like that from the 1920s on, so it might be that the problems of the aviation industry were specific and not rooted in the general economic developments.
But I'm not an expert in these things!
