Glass' Suggestions
There needs to be more aircraft, first off we need some Soviet Fighter Jets, Stratofortress already made the A-10, F-18, P-51 and other american things, but we need to spice it up a little with Soviet jets.
I also think that people that make jets like these should use Stratofortresses HUD and Weapon Selecting for their planes, and also integrate his flare system so all the planes can use flares to fend off missile attacks no matter who made the plane. Also use his landing gear system, because who likes to fly a plane with landing gear down, it just looks stupid.
Civilian Planes. We need some more of those, like small propeller planes and what not.
Drones could be cool as well. Like a
RQ-4 Global Hawk Surveillance UAV that could be pretty cool, like you can take briefcase, right click the plane to sync it then when you go to wherever you want to control it, you hit /UseDrone or something.
Anyway those are all my suggestions. Feel free to post some of your own and I will add them to the thread.
