The problem I see is the huge moral hazard that was present long before the C-Series reached its parlous state. The company (read: the family) believed rightly, as it turns out, that however bad the decisions or the execution, the Canadian government (read: taxpayers) would bail them out--too big to fail guaranteeing failure, as it were. BBD has repeatedly seen their bad bets covered so press on design/building three new planes AT ONCE, using unfamiliar technologies and with a record of poor process engineering.
