Here’s the thing:
Airplanes have a limited lifespan. The 747 is designed to last 30 years. So why not buy a new copy of the original? You can’t.
The VC-25A is based on the 747-200B, which was discontinued in 1991. And all of the customizations are specific to the 747-200B.
Thus, the entire design process has to begin again.
Personally, I wouldn’t mind if Donald Trump couldn’t function as President while flying around, but the idea of the plane was that the country would be better run with a flying white house.
