Walk-around of the LOX fill/drain fitting.
Picture 2 of 3.
I believe that the screen on the end of the center fitting was added when the
stage was displayed outdoors and would not be present for flight stages.
I was surprised to see in launch videos (e.g., video 1, video 2) that,
unlike the liquid hydrogen fill/drain
fitting, the LOX fill/drain fitting had no aerodynamic fairing.
