This is a huge blow for the Canadian aerospace industry, but the best that BBD could do in a bad situation.<p>The plane itself is great, but management incompetence and customer worries about the company's long-term prospects made it a hard sell. Then, when BBD <i>did</i> make a sale to Delta, Boeing's naked politicking and the current administration's unreasonable duty made the situation untenable. BBD is essentially handing over the keys to the kingdom here: Airbus gets control of the program for nothing (they only have to allow the C series to be manufactured at an existing plant in Mobile) and if the program is successful they have the right to buy out the entire partnership; if it's unsuccessful they can walk away. Plus, it's unclear to me whether it's a way to actually push the C-series or a way to start conversations around it and then upsell customers to one of Airbus' existing narrowbodies. Again, not a good situation for BBD.<p>Airplane manufacturing is a heavily political, heavily subsidized business, and since Canada is much smaller than the other players on the stage (US, EU, China, Russia) with a non-existent defence program it doesn't have the money or the weight to effectively compete.
