Thanks very much.
I have one point, and it may be a naive question, but you brought it up. Airlines around the world don't go with one airplane. They have a number of different manufacturers with the fleet that they have. I think back to the issues that Boeing had, going back two or three years, with the 737 Max issue that got screwed up.
Are there other air forces out there that have a number of different models, or do you pick one and go for the whole thing?
