So these planes are being developed just to assemble the 787 not to compete with Airbus?
I'm sure if some other company needed a large freighter, Boeing would be willing to manufacture more of them. This is just a conversion of the standard 747-400 passenger aircraft of which more than 500 have been built.
Yes, these are cargo aircraft no passenger aircraft. Possibly Boeing will make more for other airlines?
It's also not competing with Airbus because all of the plane, other than the cockpit, is unpressurized. Absolutely lethal for the passengers if it were a pasenger aircraft.
