Wow those comparisons are way off.
The cabin numbers they list for the G550 are quite wrong. They show (w x h) 84″ x 72″ while the Gulfstream website lists it as 88″ x 74″.
They completely overstate the size of the Global Express. They show 98″ x 75″ while the Bombardier website lists it as 83″ x 75″.
Bombardier won’t have a comparable airplane once the G650 is online.
