Yahoo maps shows that zip-code for 5000 Longmont Dr., Houston, TX is 77056 not 77027 as addressed in memo #1.
Zip codes change through the years, but good point nonetheless. I was referring to the squadron address. There must be some 1972 source that can tell whether the mailing address of that unit was PO Box 34567.

Likely a dead end. The zip code of 5000 Longmont is now 77056, but 77027 is adjacent, right across the freeway. Most likely the zip code 77027 was slit up during the rapid growth of that area of Houston in the last 30 years, it is the Galleria area that has filled up with highrise office and residential, Houston's second downtown. Also 77034 is the zip for Ellington Field, and since the military assigned the box #'s for that base, it wouldn't be unusual for them to chose an easy to remember # like 34567 for the squadron's box.
Plus if these are fakes, I just can't see someone being so incredibly sloppy, in something so serious that will be scrutinized to the nth degree, as to make up an address that is so easily cross-checked. The Dem Sasso and Pellicano types are pro's. Then again, some of those signatures look questionable. While there is often a wide degree of variance(depending oh hand position, what's underneath, etc.) in all the various signatures of a person, some of the 'K's in 'Killian' are completely different in style, far different than would arise out of sloppiness or the other usual variables.

The two post offices appear to be less than two miles from each other. The 77056 post office is west (outside) of Loop 610 and south of the Galleria. The 77027 is east of Loop 610 (inside). As I recall the Galleria was built in the early '70s. Someone should check the plaque on the post office for 77056 to find out when it was built.
