Dear Doug,
I'm not sure this accounts for the vertical proportional spacing (modern wordprocessors automatically adjust the space between lines, typewriters didn't, the "memos" are vertically proportionally spaced), or the kerning.
As another poster suggested, perhaps Lt. Col. Killian was writing his personal memos on a typesetting machine, and taking the time to do the kerning, too.

No go. The Killian widow and son have both said today repeatedly that Killian didn't know how to type and didn't take lengthy notes of anything.
Plus, more is coming out. The abbreviations used aren't typically those used by the military, the dates are accurate to military use, the date for the physical isn't per military rules, etc. The holes are getting pretty darn large.
