Many thanks for the newly released CIA document, tartare. The old document, apart from being heavily censored, had pages 154 to 156 missing. So no mention of British involvement.
It is interesting to see that Operation Robin is mentioned several times, where the RAF flew a modified Canberra on a photo reconnaissance mission to Kapustin Yar.
I wasn't aware that when the RAF pilots flew missions in the U-2. That the title of the aircraft would be transferred on paper & full responsibility for that mission was with the British Government.
I was also not aware that during the two years that the RAF pilots were at Detachment B, that the RAF flew 27 U-2 missions to the Middle East.
