Would the 747-400 sell as many as the 747-8 (cargo)???
Was there really a need to enhance the cargo version? In my opinion no because Airbus have and will not have a suitable competitor against the 747-4.
The 747-8 is purely developed for the passenger version as an answer against the A380.
So if only LH will take the passenger aircraft it seems to be a failure (which I don't hope). Why a failure; because the 747-400 would have been selling the same amount.....
What do you think?
