Fascinating content, but interrupted six separate times by a "Type your email... Subscribe" text box. I wonder what the conversion rate is on that fifth box; who misses it the first four times and then decides to sign up? Back on topic, I do hope that some of this is simply being withheld and is not truly lost to history, but it does make one wonder: At what point will the digital information inside secretive state agencies like the CIA be analyzed by, say, 3rd-millenium historians, in the same way that we analyze cave paintings? I enjoy reading through some of the declassified Apollo mission engineering documents, but I would be shocked if a future government was willing to release such shameful material even decades after it was no longer of strategic importance and the individuals involved were all deceased.
