I have a few Victor MR sorties in my logbook. Somebody thought it would be a good wheeze to train the tanker force for the MR role. I recall it was stultifyingly boring. We would go to a designated area over the North Sea and pick a ship's response on the radar and work out its MLA (mean line of advance) using the H2S radar and the Navigation Bombing System. Trouble was there were so many errors and slippages built into the Heath Robinson electro-mechanical innards of the NBS that reliable results were all but impossible. I remember calculating that my "ship" was tracking 270 degrees at 10 knots. All well and good until I found out it was a static gas rig!
Fortunately after a few months the whole idea was quietly dropped and we went back to dispensing fuel.
