Most excellent diagram. On this A300 one sees three towers, keel to spine, of four faces, with extensive bridgework, that support each saddle which in turn receives the three pins that mate the VS to the Fuselage. They are extensive,and impressive. Take note also of the "lateral rods" detail.
Though the 330 has the rods, the superstructure that fixes each saddle through the fuse and to the keel are not present. What do you make of that??
