Interesting fact I recently paid attention to.
During the war there were 12 extended range Nimrod patrols from Ascension Island; 4 more than Black Buck missions.
Each of those patrols required an inflight fueling mission of 12 Victor K2s.
And I would guess at least one reserve Nimrod.
If you ever want to really add flight hours to your ticker, build the Airfix kit.
