@ weido salt:
Do I read any negative vibes in your comment? Is this the old 'Francophobia' that used to be notorious in your area?
Let's face it, any new machine is prone to growing pains of any kind. Be it French, American or whatever. I don't know why the big airframers keep making the same screw-ups and promise things they can't keep. The A380, A400M and B787 are only the most recent examples.
But I know this for sure: the 7X is a very nice and powerful machine which is capable of doing the same as a G500 - at a much lighter mass (= minus 24,000 lbs or so) and at higher speeds. Whenever this thing is fully ready, it will be fun to drive.
And yes, in terms of salary this should be in the same category like the Gulfstreams. Particularly considering the exclusivity of being in the club of holders of a type rating...
