Fortunately the Tanker exchange programme with the USAF through the seventies and eighties did not lose any participants but it was very noticeable how hard the guys, with one outstanding exception, found it to work to our style of operating. They were obviously controlled far more tightly from some form of central organisation and took some time to feel free to make their own decisions. The different styles of the two air forces were most noticeable when operating together, with RAF tankers almost always the preferred choice.
