I dont think so, that he is correct with his pressumption. Airbus still has the ability to increase the capacity of the a380 while Boing has allready reached its limits with the 747.
fear-not.......you are a very brave man to say that the bloke who designed the 747 is incorrect!! I'm afraid I'll have to believe Sutter until you can convince me with something more conclusive than sweeping statements about the 747!!
