I purchased a digital copy of the C-130B/HC-130B/C-130E flight manual. The manual clearly shows THREE fuel access ports on the upper wings, including well inboard near the root (#13 on the drawing key), but NOT one well outboard. It’s showing one on the external tank (on the C-130E), but only three on the top of the wing.
The manual also clearly shows three blue formation lights, set in the upper wing aft of the rear spar, all well outboard, all outboard of the engine nacelles. There are also three of them on the fuselage spine behind the wing.
But then look closely at the R8V-1G photo again. On the starboard wing there are four circles on the outboard wing section, set well aft near the aft spar, but none inboard at all. On the port wing, these circles are well forward, just behind the front spar, again with none inboard at all.
I know it’s not the clearest of photos, but I don’t see any of the blue formation lights, either on the wing aft of the rear spar, or on the fuselage spine.
The more I look, the more confused I get!
