Briefly - not to bore PPRuNers.......
The GR3 could balance fuel, but not "move it around".
I think we did 4/5 plugs on the UK -ASI flight. I seem to recall that they might have done a few more on the ASI-HERMES flights. Always topping up rather than going from empty to full - probably about 4/5000lbs per plug. Keeping diversion fuel was the key, plus the tankers had their own need to refuel each other and give away before going home or going to a friendly airfield - Spain was not "friendly" for the UK-ASI flights. Yes, the fuel used came from the drops before internal.
