Jackson, Peter Easter Egg - Peter Jackson Plane Gunner

Look at the credits carefully. Under the cast section there should be a section entitled "Gunners". On the left hand side of the list (there are 8 altogether) about halfway down there is a gunner called "Peter Jackson" Who is the director of the movie?
Yes, Peter Jackson. If you knew his face it wouldn't help as it is covered by goggles.
Happy Viewing :)
