My recollection is that Boeing essentially had insane tariffs applied on US imports of Bombardier commercial aircraft after Delta made a large order & was preparing for delivery. Shortly thereafter, Airbus came in and acquired a controlling stake of Bombardier Aviation, took over the CS planes, and agreed to manufacture them in the US (Airbus manufacturing is in the EU). The way it played out seemed to me as if Boeing and Airbus conspired to kill off a viable competitor after they saw how well received the CS100 and CS300 were. This is all on top of the overall financial troubles the company was facing. I could be entirely off the mark, so I will let those more knowledgeable chime in from here.
