Note 1: The value in this code is less than the total armour on some of the aeroplanes in the game.
Thus, when the cash is calculated at the end of the mission, it can deduct some for having lost some
armour. In order to get around this, put a higher value than 00C8, say 0190, into the code. This
will also have the side effect of giving negative damage at the end of the mission for some lighter
armoured planes, and hence give you a cash bonus.
