I recently downloaded FSX Air Force One Boeing 747-8F Package with Advanced VC.
It looked good, it carried the number 29000 on the tail under the US Flag.
I was pleased....until I was flying below 10,000 ft and put the landing lights on.
The tail became illuminated and changed to Emirates Colours!
Was this a joke by the repainter, Aziz Palas?

On the other hand, I can see a benefit by having AF1 display colours of the country it makes official visits to, on the tail.
A good idea!
