Expanding Germany's Airports

According to the Handelsblatt, German politicians are arguing that Germany's major airports urgently need to be expanded.

The list is long: Frankfurt, München, Berlin, Düsseldorf, Köln/Bonn, Hamburg and Stuttgart apparently all require a substantial expansion. Emphasizing the role of airports for "growth and employment", the transport ministers of the federal government and various state governments think that the "future of German exporters" depends on an adequate expansion of airport capacity. If capacity is not expanded quickly and aggressively, air cargo traffic will move to Holland and France. Due to the sense of urgency, they suggest that cost-benefit-analysis and updated demand projections are unnecessary and should not be carried out.

I see. Has anybody told them that both passenger and air cargo traffic have been plummeting for more than half a year, and any recovery to pre-crisis levels is likely to take a long time?
