I'm not saying the ARCCK controllers are error free - sometimes it is a function of not having aircrew with SAR experience in there any more.
However, they don't deliberately task RAF assets into MCA patches just to pi** you off, there will generally be a good reason, whether it is to do with weather, availability of MRT or doctors, likelihood of the job extending into night (esp in the mountains) or a whole host of other reasons.
It might be just to preserve your asset in your area or, as I mentioned in the previous post, because the RAF asset is already airborne and will have a faster reaction time (despite your superior speed of flight).
We all love to poach each other's jobs but get the ARCCK to update their information if you think it is wrong.
