I love old airplanes. As an engineer and a photographer, I see a lot of beauty in the mechanics of the old planes (and almost any old machine). This is the machine gun magazine for a P51 Mustang from World War II. It is strange: I used to work in the defense industry, but really had a hard time with "making killing machines". At the same time, I can't help but to be drawn to these old military airplanes.
