Today I was looking at the production numbers of Russian built airlines on wikipedia (which I realize isn't the best resource) and it seems to me that they can't produce the same numbers of planes in the same amount of time such as Boeing, Airbus, Embraer, and Bombardier.
Why can't they keep up? Is it a lack of demand? Is it that they don't have as strong supply chains? Or is it something else I'm missing?
