mmmm, are u sure piston 100 per 100 ?
when developer could write lines of code for aircraft when i launch missile that fighter's like f-4 or f-105 diving to earth so hpasp could create little more norm randomize coding for (different run method) from missile! u want say : in visual basic 6 developer only could add one code for each aicraft for run from missile !!!!!!
