Thank you for your replies! I only got 3/10. By the way I asked about Bombardier in particular because some sources say that their annual revenue for 2018 was ~16 billion, but I guess that includes revenues from non-aerospace branches. I know first-hand how tough it is to get good sources for more "niche" quizzes like this!
Appreciate your feedback. Bombardier and Embraer aren't there because they make short ranged Jets and private Jets and these things do not cost much. Here is the link from where I got this information (annual revenue).
