Here's hoping that like myself, you have never seen any of this footage before.

These are engineering films from the Apollo program, and show stuff like the insides of liquid oxygen and hydrogen fuel tanks during launch. Bunch of other views too, some pretty Kubrick-like. Last shot shows how they got the camera back. About a dozen film clips here, released in the last year or so online.
