Nitpick: in Bombardier's case at least, these were separate events. The acquisition wasn't to deal with bankruptcy (they got a Canadian government bailout for that), but rather to gain access to Airbus's US manufacturing facilities to avoid import tariffs on US deliveries, which became necessary following a Boeing anti-dumping complaint that would have made the C-Series prohibitively expensive to US carriers. My recollection is that Bombardier made (rejected) overtures in Boeing's direction before the trade spat. In either case BBD has gotten out of the commercial aircraft business completely, in large part due to the cost of developing the C-series.
