The t-4 can emit white smoke screen vapor, either to imitate getting shot down, as pilots would in training, or for stunt flying. To do this, hop in the T-4 of your choice ( i prefer the blue impulse scheme), and press TRIANGLE (the fire button) to start emmitting the smoke screen. You have infinite as far as i can tell. Set things up for great 'watcher camera' replays, stunt show style!
