As I remarked earlier what we have is only the French version. We don't have any access to the German version of events though if that's the stand of the Germans , it doesn't make sense or logic . I don't think anyone would agree to it but I don't know who would make such demands in the first place & then hinge progress of the entire talks on this one premise.We can help you make a development and share ownership with you, but not give you ownership rights to developments that were made before without you. We have been investing in military aeronautics for 70 years and the Germans would like to be on the same level as us after the SCAF programme, even though they have bought most of their aeronautical equipment or produced it in cooperation without having the most difficult parts.
