FY certainly did have a dispersal role in the early '70's. My 1st posting was FY in '75 and I recall arriving in ATC one afternoon to see 4 x Vulcans on Delta Dispersal (SW corner on the airfield) and the 'Bomber Box' Hadley bleeping away in Local Control.
I almost wet myself when "Attention Attention, This is the Bomber Controller for Strikelist Hotel, Scramble, Scramble, Scramble" came over the 2 core wire from Bawtry. (In my defence, I was young and impressionable). After all, having watched Varsity's, JP's and Dominies doing their stuff, to see real Air Force was somewhat else.
Sad, I know.
