"Carryall=yes" can't work!

[Mevitar]

you can't have the dock= and AirportBound=yes if you want the carryall=yes to work!

no AirportBound

From what i can see, that's what Graion tried to say...

And that's pretty much how it worked in Tiberian Sun, by the way. You needed an aircraft without AirportBound and Dock= set, so i don't see a reason why it needs to be changed. This part of carryall logic wasn't modified, it works exactly the same as in TS.
