Yes, there are.
Freeper reporting that some guy in Atlanta with a radio show (Kimmer) has said, without equivocation, that the documents are falsified.

From a new thread:
Okay, guys and gals. As a former Air Force officer and special agent for the Air Force Office of Special Investigations (OSI), I have reviewed the documents released by CBS and can say with a high degree of confidence they are fake.
1--the month in a military date is always three letters. August is spelled out.
2--no one issues an "order" through a "memo." Maybe a letter, but nothing as informal as a "memo."
3--the signature (initials) of Lt. Col. Killian is clearly a cut-and-paste job. The last letter ("K") is cut off at the top, where two lines start to curve toward each other in a loop. Impossible to to do by hand. This signature was cut from another document and pasted or taped on the document.
4--No letterhead. Do you really think commanders typed out a the squadron on every letter? No. Letterhead was used.
5--No way there were superscripts back then. No way. Even if it was theoretically possible (which it wasn't), the national guard isn't exactly an early-adopter of technology. This ability wasn't even available at any price for several years.
Conclusion. I think they're fake. As a lawyer, I can also tell you this kind of thing is far more common than people think.
