Bombardier is increasing its CSeries program transparency a bit. Take a look here for images.
There clearly has been a lot of progress. There are three airplanes in the factory at various levels of completion. We understand the engine certification is occurring soon. Bombardier continues to be cagey about first flight but if the greater transparency is any indication, they probably will be flying before the Paris show this year.
It sure is a pretty airplane. Note the finish in the first picture.
