nacluv thanks for the photo links. That helps to explain what I'm getting at. The top machine is a PR9, the lower aircraft is also (technically) a PR9 although it's designated as an SC9 (it was a non-standard RAE machine). As you can see, the tip tanks are not actually on the wing tips, they're attached to the tip of the original B2 wing structure, just inboard. However WH973 has the same longer wings, but the tanks (they're actually equipment pods) are on the actual tips. This is the mystery - why would they be there?
