You have shown two different aircraft because one of them is clearly much longer, but both is called the Global 8000? Is one a standard version and the other a stretched version of the Global 8000?
Guy clearly has no idea what's he's talking about. The short version, the original one, was cancelled, or better said never lunched. The long version, a different aircraft by the same name, based on the Global 7500, is the one Bombardier's actually making.
