Hello Goran, i've been flying the virtual skies since Fs4, till i discovered x-plane and I remember, that 747-200, i just purchased from Vmax, and the name of the principal designer was Ralph Tofflemire, this was a piece of art for that, sim i think this was the first aircraft with a refuel panel and fuel jettison, very complex and a very detailed manual, ooops i've forgot, it has INS, She was pretty and flown like a dream. I' ll be a customer of your 747-200 for sure. Thank you very much, for your great product.
