OK more brain fade. You are probably right and it may have been Wittering who certainly would not have been able to generate 16 Blue Steel.
IIRC Wittering ceased Victor ops in 1968. early '69 at the latest. I know that Scampton was involved as I discussed the event with a couple of mates on 27 & 617. Finningley?, OCU was just wrapping up there, first Scampton course was in Jan 1970. Did they have any weapons at Finningley when the OCU was there?
The 25lb PB in the NAAFI car park had a V-Force dimension. The pilot was an ex Vulcan copilot (the name can be forced out of me by the judicious application of pints of Bass). He and I did a bit of QFI'ing together in later years.
