Tester07,
Thank you for those kind words. The CSeries Chief Pilot posted a poignant photograph of FTV1 flying off to storage in company with FTV4, which was also leaving to be refurbished and sold. They must be pretty confidant they've got all the data they need in the bag.
In the context of Flight Test employment, I wonder if there now will be one of the usual exits of personnel to one of the other Wichita companies or even to Mitsubishi.
