Before clicking on "Single Mission" hold down Alt, Ctrl and Shift on the right hand side of the keyboard.....You will be able to fly all the Single Missions from the three previous Jane's games (USNF'97, ATF, Nato fighters).
Before clicking on "Quick Mission" hold down Alt, Ctrl and Shift on the right hand side of the keyboard, before doing all this make sure the "Fly All" option is off. Keep on holding it down while you are choosing your plane until you click on "OK"...you will be able to choose all the choppers and two other creature type of planes.
