When loading an aircraft with the appropriate rounds to fire the on-board guns, they don't fire. Is there a specific button I need to press because if so, let me know. I run a small server with friends and I want to fix the problem as fast as possible so we can go back to messing around in the air. Also, even though I load the M45 anti air gun (the one from the Americans) with the proper 50 cal ammo it still doesnt fire. If anyone helps me, I'd be glad to let you and whoever else into the server as a show of thanks.
