So if , as is suggested, the C-Series are a step change in aircraft design, they will sell across the world, and once again the US domestic carriers will carry on with outdated 75 and 76 clones.
Irrespective of the funding issue, C-Series are simply technologically ahead of anything Bubba can produce hence the angst up in Seattle and on the hill.
Perhaps Bombardier should undertake a few more demo trips around the US and get more airlines to push for change. It makes more sense than trying to overcome the corruption and vested interests involved.
It took something similar with Airbus to make it happen for them, it just took a while.
