Cheetah,
Good questions, I believe the contract was signed, but at number 99 Saudi declared “open skies” which affected the Saudi operators route feasibility for 145’s, so to see if it can work they requested 120’s instead, meaning the 145’s are not quite out of the picture but they certainly are delayed. That’s aviation for you.
As for the so called facts, posted by the two M’s. I know both individuals JdK sold his Merc about a year ago, CB never had a Merc that I know of, the closest was a Japanese copy made by Toyota. So, so much for that fact.
