I firmly believe based on what I've heard and read about the C Series planes, that Bombardier has developed and produced a truly innovative plane(s) here!  Still at a complete and total loss, why Boeing chose NOT to seize the day and form a partnership with Bombardier over its C Series plane(s) as Airbus has done!!???  Choosing to hide behind and/or use the protectionist power of the US government to stop the entry of the C Series plane into the US market, has to be one of THE least innovative and cowardly business decisions Boeing's executive management has ever made!!!
