The basic idea of the map is the title, but now for more background;
This map is a massive cargo plane, it might need to be bigger than your traditional cargo plane because there needs to be enough space to drive around.
There can be a ramp or something in the middle of the plane down to the cargo area.
Just for the fun of it, if you can do it- you should make it to where if you were to fall off, the vehicle would be launched backwards as of the plane were actually moving and there was wind.
