Fair enough none of my old aircraft books even mention the A 12 only the SR 71 let alone the Oxcart codename or program name and as it was a CIA aircraft unlike the SR 71 which was USAF it is only mentioned in CIA sources The U2 never had any codename defacto or otherwise I m 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
