Fair enough none of my old aircraft books even mention the A only the SR let alone the Oxcart codename or program name and as it was a CIA aircraft unlike the SR which was USAF it is only mentioned in CIA sources The U never had any codename defacto or otherwise Im satisfied with the extra paragraph in the introduction that explains the association and will not seek to push the matter further but I do feel strongly that the paragraph in the intro explaining the association not be edited out in the future
