Optional Freight or Cargo mode?

I think it would be a stunning update if there was a optional freight or cargo mode! The developers could implement planes like the…
•MD-11F •747F •Airbus Beluga •Boring Dreamlifter
And many more to bring the cargo market into the light because of all major airports in the real world also have Cargo terminals!

First of all, I am assuming you mean Boeing, not boring. Yes, I do agree with you. However, people would probably have to choose between cargo and commercial at the beginning of the game, because of the amount of land to work with. Otherwise, go check out my discussion on how land is small and needs to be expanded.
