Thank you. And I have perhaps a final question.
One of the issues, obviously, for many NATO or allied countries is the issue of affordability, both from an acquisition perspective and also from a long-term maintenance and operational perspective. A number of European countries are going through difficult budgetary constraints, as well as other partner countries.
What can you tell us about the affordability of the Eurofighter, and the stability of the costs in terms of having an accurate sense of where the costs are and will be going forward?
