Overall view up the tail unit. Note the aft bulkhead of the LOX tank between the "triangle" near the top of this photo.

Also note the bellows section where the braided cover has peeled back on the S-3D engine's fuel high-pressure duct (top-most silver line, which forms a right-angle).

Three vertical structural elements run the height of the tail unit; two are visible here while the third is hidden by the engine. Details of the one at left are at dsc33429.jpg and dsc33411.jpg while a detail of the one at right is at dsc33413.jpg.
