SA-7 16mm Motion-Picture Camera
    
    
    
    MSFC developed two types of cameras for the Saturn I.  The SA-7
    mission camera on display is a Model B used for "indirect viewing" of
    hard-to-reach areas such as inside a propellant tank.  A flexible fiber-optic
    tube enabled the camera to see around corners.  Model A cameras were used for
    "direct viewing" of events such as stage separation.
