At the time Bush was an F-102 pilot, I was serving as a meteoroligist providing support to another F-102 Fighter Interceptor Group among other units. I had occasion to give weather briefings to the other pilots in his squadron, but never had an occasion to meet him. I know for a fact that the Air National Guard fighter interceptor group I supported absolutely did not possess a typewriter capable of producing the Rathergate documents. I have every reason to believe Bush’s unit/s got exactly the same types of typewriters from exactly the same depots as ours. Furthermore, I was using the IBM Selectric Composer at the university to prepare camera ready copy for publication in 1971-1972. The Air National Guard did not have or use those for any kind of routine secretarial work, and our fighter interceptor group never owned one.
My wife was preparing financial statements for her corporation, and they needed a character that was not available in Letter Gothic on her daisywheel. Since I was working for Xerox, I custom ordered a daisywheel for her company which replaced the existing character for the one she needed to print the reports. However, that was in 1981. Although companies could and did order custom type bars and type balls for typewriters in earlier years, the Rathergate documents used characters not allowed by the Air Force, and the typeface and character spacing were impossible without the use of personal computer word processing software used with laser or inkjet printers decades later. The Rathergate documents were very obvious forgeries. The way in which they were afforded any consideration of legitimacy at all was utterly lunacy when seen from the basis of experience within the offices of these air units.
