We'll have to maybe get somebody else to come to tell us about that.
Thank you, General.
I have one other question. Interoperability is an interesting matter that we talk about that from time to time here at this committee. One of the groups you worked with was the Romanian air force, which operates, I think, the MiG-21, and you've operated with all these other aircraft as well.
Interoperability, I guess, is more than having the same aircraft as the others; it's about being able to work together. Did you find that's something you could do? Obviously, they learned from you and you learned from them about how they operate and how those planes work. Was that a success with all these groups?
