No RAF pilots went to Stalingrad!

Ok, it’s very early, I haven’t got book in front of me for exact detail so excuse vagueness..
Just re-reading Leo Nomis’ book Desert Hawks which is about his time spent serving as a volunteer with the fledgling Israeli air force flying 109s…but he also touches upon his service with RAF during WW2. In that chapter he mentions that the RAF was poised to send a squadron or two of fighters over to help the Russians in their struggle to defend Stalingrad. Any truth in this?

After reading the source from the BBC I think only the aircraft went to Stalingrad with Russian pilots in control.
