I love this mod so much, right now I'm building airports all arround the world. This brought me the idea to build a "save haven" by filling the center of a huge sea with land and then make a military base out of it. Wouldn't have been possible without a plane.
I would love to some different styles of planes though! Maybe there could be a cargo plane, with a huge trunk but also a big hitbox and less acceleration so that you have to have a longer lift-off-area? And what about a propeller-driven aircraft which is more affordable but then again slower, less cargo capability and higher fuel consumption?
