http://www.winzip.com) get the demo of winzip (you can use it as long as you want, no expiration date), and open allied up, then click file, open, go to xwa missions directory, open up battle5mission1 (should be abbreviated, double click on one ofr the ships on the left menu, make sure it doesn't have .ai anywhere when it brings up another menu, and where it says ship type, there's a drop down menu where you can select any ship in the game, select any of them (just don't do a capital ship, 'cause that'd probably cause a crash, a shuttle or transport would be ok i think), then save the mission as it is (just overright the mission, if it doesn't work, you can just get the mission back from the xwa cd), and then load up xwa, and go to skirmish, battle 5 mission 1, and go to the hangar, and the ship you wanted should be the main craft.
