???How do I install new airplanes to the original campaign in Combat Flight Simulator 3? I am asking because I want to add more accurate versions of the default planes plus some "should-be-there"* models.

*b-17, hurricane, stuka, a-26,etc...

I found out that modifying the campaign's XML file in the campaign's folder can be useful if you want to edit certain campaign features. You can change things like the amount of supplies that is used up in invasions, adding news headlines etc... I was able to confirm this by actually fiddling around with a copy of the original campaign. The problem is that when I try to install a new aircraft like the A-26 the game will not read it. I tried adding some new lines to the aircraft section of the file, but the game wont accept it. IF ANYONE CAN FIGURE OUT WHAT IM DOING WRONG PLEASE TELL ME. Combat Flight Simulator 3's original campaign just seems incomplete without the ability to fly a Ju-87 Stuka...
