Airband Frequencies for the B-52's out of Fairford?

Hello,
Is anyone tracking the B-52 flights from Fairford to Iraq on their Airband scanners?
I live in Bristol and am scanning a number of Fairford Frequencies, and I believe I heard them tonight on what was described on a website as a B52 Air-to-air frequency. about 20:10GMT.

But I just have Fairfords freqs, I assume they contact other ACCs on the way?

Just wondering what frequencies they use when flying over/near Bristol, assuming they are going my way.

Thanks
