With a little practice, and the same armament as Gutted was using you too, can kill countless targets. If you will look, he is using Gun pods, I recall Him stating that, and the use of unlimited ammo, after making the movies. I liked his Superbeast one better. No matter how he may, or may not of made the shot, the view from the cockpit is a great learning tool, and I've watched it over and over through out the years, and passed it along to others aswell.
As for Crash's movie loved it the first time I saw it, and it too is on my HD along with many other little IL2 movie gems.
