Now that the Frankentanker has such enormous winglets, completely changing the flutter characteristics and vortex field of the old 767, pod aerodynamics will be a different problem than it was for the useless Smiths pod.
But Cobham should manage to solve it. A small tweak to the 907E sorted drogue nutation very quickly (not that it was actually that severe) for the A310MRTT.
It'll be interesting to see whether those big winglets will cause receiver pilots any disorientation issues when maintaining close formation in poor visibility. Probably not, but did anyone think about that?
Competition is no bad thing; the fact that the USAF chose second best is their problem. But their paper plane will have a significant UK content.
