I hope you had, and continue to have a happy thanksgiving. To clarify, SA and 'moot are ok, but something like RAF is something modern and thus not ok for Dwilight?
Basically, don't look specifically for abbreviations you can pronounce. "Backronyms" like the "USA PATRIOT Act," where you decide on what it should be pronounced as and then work out what each letter stands for, are the worst.
There's not really a problem with "R. A. F." as an abbreviation for "Royal Air Force" (aside from the fact than an air force wouldn't exist
); you just shouldn't have people pronouncing it as "Raf".
