Another Possible Forgery
I decided to practice what I preach and analyze some documentation myself. Here is one of the memos that CBS has released and say that their experts have verified it as authentic:

I noticed something peculiar on close examination, though. While this memo is mono-spaced like most typewriters from the era, look closely at the spacing. There is 1.03mm of space blank space between each letter but, in 1973, the common blank space between letters was 1.07mm. Typewriters with 1.03mm spacing between letters are those more common of the 80's. Thus, I am 65% certain that this is in fact a forgery.
I'm still examining the PowerPoint slides CBS obtained which are reportedly also from 1973 and detail how Bush was AWOL, and, if I find any historical inaccuracies in them, I’ll report back.
