the planes arn't that bad its just that CFS2 wasn't designed for jets and guided weapons.
Guided weapons were used in vietnam, but not such a big way. (GPS wasnt invented yet, another method that used a laser was used in bombing) Even in the first Gulf War guided weapons were not used as much as un-guided weapons (correct me if im wrong, im forgeting all this stuff) Although guided bombs
were used in nam, un-guided ones were used much more. I myself would be glad to see the intruder in CFS2, even if the weapons arent guided.
PS: There is an Fs2000 and Fs2002 A6 here at Simviation, but i dont know if it will work in CFS2.
