I posted this question on another thread, but how were corrections made? Is this before auto-correct on typewriters? It's unlikely these were typed with no mistakes isn't it?

Don't know how the military handled it, but I'd think the standard would be lower for a memo than on other documents.
For this private sector crappy typist, mistakes were a total do over & we're talking pitching out all carbon copies.
Later, we were allowed to use sheets of correction stuff. You put the handy dandy sheet of correction film over your boo boo & retyped the same wrong character & then you could type in the correct char in it's place. Occasionally, your fingers would get in the way while you were holding the sheet of correction stuff in place, so you could end up with a letter typed onto your finger.
Here's the thing though, with the fancy machine used on these docs, the spacing is gaged different for different letters, so if the correct letter was a different width, you'd be back to doing complete do overs again.
It was cool when that Monkee's mom invented Liquid Paper & even better when that came in different colors, cuz you could correct all layers of your NCR paper multi-copy forms without leaving large swatches of glaring white, though you had to run all copies back through the typerwriter again, cuz the chemicals of the NCR paper didn't work through the Liquid Paper. :o)
Wannna hear about keeping the books back in the dark ages too? lol
