Variations are just plugs in the fuse!So what there stretching the C Series, whoopie do. Not all that difficult in the scheme of things but. How about a few small steeps like getting the C Series that are actually flying over to where potential customers might give it the nod! How about ramping up production to accelerate deliveries. It's always the next great feat when the one at hand hasn't been proven yet. It was only a few weeks ago, the C Series wasn't even going to the AirShow? Now it's bigger bluster to make all ready vanishing dead lines seem insignificant! Credibility is being humbled by boastful arrogance at a time they need to be cautious.
