Dave,
My mistake! Working from memory and memory appears to be broken. It was in fact the aforementioned G-VBIG that I saw leave LHR (13th January) and I followed it on Planefinder up to Cambridge. Mainly due to this being after Virgin had withdrawn the 747s from LHR. (until the next one!)
Perhaps G-VROY was in the back of my mind at the time. I have often seen this one at Manchester. Sorry for the confusion!
