FFA - Free For All, that means you dont need to be pilot to fly a plane or to be crew member to drive a tank -if you have money do what you want to do :)
Mission have been tested for about six month on our server, and everything works as it should be ,so you just didnt notice the message "prepare for the enemy contraatack" .
All idea about our aircraft is that when objectiv is close its stupid to fly becouse theres more chance that you be burned by enemy antiair defence, when objecktiv is far away its safe to use planes and helicopters, but if you have balls and money you can take a risk, worst thing that can happen - youll die like a hero.
