I work in Aviation and most of these clowns have no idea the cost and upkeep is for a private jet.. much less a 767 which limits where you can fly.They will fly them hard the first couple of months and then realize how much it is to operate.
Crew, fuel, maintenance, insurance and don’t forget Landing Fees! Governments make money off landing fees on large commercial type air craft. A small jet not’s too bad, but a 767 watch out. And the limited landing locations due to the length of runways required. Yep he made a costly mistake!
