ORAC, thanks, but the first is expected Russian targets in UK, not RAF targets in Russia.
The second is the SAC list and the Bomber Command targets are included in this list. I am looking for the UK plan which I think was just 38 targets. Considering force size at the time and at least 5 targeting Leningrad and at least the same on !Moscow, there would still have been enough left for at least 2 per city.
