As mentioned in the post on The elusive Col Tomb
This is an amazing document originally published in classified form by the NSA in the 1980s for internal training, then declassified and released in 2007. It gives perspective on an amazing swathe of history through a rarely-available lens.
You’ll note crossed-out classification markings throughout and codewords, which denote intel from intercepted communications. And some parts are completely “redacted” (blanked out), which always fires the imagination. What are they not saying?
Here’s the official “declassification” stamp, showing a Freedom of Information case number.
Even the preface is interesting. I wonder what’s in the separate History Office study?
The most airpower-relevant stories are in the Vietnam sections, and I’ve pasted in the part on Col Toon/Tomb below. Based on what’s revealed here, I can’t see how researchers so casually dismiss the legend. Clearly the NSA had much evidence of his existence (even though he wasn’t the MiG-17 pilot killed by Cunningham & Driscoll). If you know of other info that refutes this, I’d love to see it…
