Much appreciated. Begs another question too. How far stretched was the Victor force at that time in getting the Vulcan within reach? 19 aircraft wasnt it? I know the story of the in-flight ballet dance whilst they debated how much to transfer during Black Buck 1. And the emergency relaunch towards missions end. But how many surplus Victor aircraft would have been available had the bomber aircraft's reach not been so far? (given normal servicability expectations at the time). Would there have been extra Victors available to get a Bucc there for example? Tough one admittedly.
