I will do that later tonight or tomorrow.
FYI the Canberra PR9 missions staged through RAF Kai Tak Hong Kong never overflew China. It skirt along the international air space boarding China, westward as far as Hainan Island. So far I can tell you is that the 'information' gained was shared with USA, and these were combined photographic as well as electronic missions.
I recall the same XH134 flew in and out of HKG
three times within a 10 days period in 1982. I was told by my friends in HKG
that hemp coloured PR9 also took similar missions in early 90s (92, 93 ??).
I was wondering what is that belly pod was for all these years, but can't ask !! However someone told me that System III was internally mounted and not in a pod, as it was a camera system with windows. So we need more 'light' to shine on this mystery pod if it is really a System III, a fuel tank ? or what ?
BTW I can't recall any squadron marking on this PR9, and it is not surprising that it didn't carry any on such kind of mission.
