Some 'interesting assignments', indeed! Whilst I was on exchange with the USAF from 1970-72, there were two officers, Pilot and Nav, and not Cloke and Bee, who appeared at various get-togethers organised by BDLS, who were unable to talk about what they were doing in the USA. Indeed, one had to say so politely when asked by the Head of BDLS at a cocktail party. They travelled from the Los Angeles (LAX), as I recall, but I got the impression that they were based somewhere well away from there.
