They were made by someone who had some experience of military correspondence but who was not immersed in Air Force culture circa 1973

True. That is why they used memo formats that the USAF established in the early 1990s. Whoever wrote those things was unaware of the old formats that were used in 1972.

Thanks for the corroboration; I never dealt with military memos but only with the contractor (Grumman) ones under Navy contract. But everything about the "memos" says that they were created by someone or some people who did a bit of research enough to have a lot of things right - but they were apparently too young to have really appreciated the difference between typing and word processing. It really wasn't a professional job of document forgery.

You OTOH would be able to make a forgery with far fewer anachronisms in it because you (presumably) dealt with the documents of the Air Force of that era. And it wouldn't likely occur to you to use Microsoft Word on its default font. But even so, it would be easy to forget some detail and slip up.
