I am definitely biased, but the Ethiopian Q400 is the only thing missing Addis Ababa project. Nobody has made one before (for good reason), but they have a healthy fleet of 29 planes (used to be 30 before one hit a boar and crashed), and I would need at least 5 examples on the low end. It would be great to fill such a large hole in the airport, but I completely understand why they haven't been made.
