is this true or are you taking the piss?
Ask the RAF .... they left them around 55N10W to go back and refuel and then intercepted them about 35 minutes later on the way back. So 52N (about) is my guess as to where they got to before turning back.
Or maybe the RAF were taking the piss and there were no Russians there ... just a couple of unexplained primary contacts which they manufactured for us all.
Alternatively, ask the BA Captain who saw them and the escorts as he was vectored clear.
