The first memo dated 02 February 1972 is the only document with a signature block without an actual signature. It is inconsistent in that regard when compared to the others. Given the comments that Gary Killian made about his Father always signing his full name, the complete lack of a signature is certainly inconsistent with the Colonel's habits. I think Gary Killian claims he told this to CBS prior to the article airing, IIRC. There is some handwritten gibberish further down the page that I would like CBS to explain. Bath and Bush were both suspended from flying status for the same reason (lack of physicals).
The second document is missing Lt Bush's serial number, does not identify a staff member to whom Killian allegedly talked (verifiable reference), and the report was due in May not June.
