spocla, thank you for that, I wondered
Me, I don't have that problem
There were no USAF exchange personnel on the V-force sqns in the late 60s to early 70s. I can't answer outside that. The reason was that Plan B, our independent nuclear ops plan was Eyes Only. There were USAF staff officers at 1 Gp and Bomber/Strike Command but they were not allowed in the vaults and usually confined to the exercise desk rather than the ops desk.
The bomber school, OTOH, had a nav rad, probaby off B47s. George Chabot (shab bow) taught us servos and M-type trasmitters, feedback etc and I flew with him at least once in the Hastings. Intensely professional . . . but then we were Brits.
I don't recall a USAF officer on 230 OCU (Vulcan) groundschool.
