“Are there any circumstances (except for being under arms), where the USAF salutes indoors uncovered?”
Only if reporting to a officer “as ordered” in their own office. (usually only if your in deep trouble).. that is the ONLY circumstance outside of being under arms.
I was agreeing with you by the way :-)
I know you were, but your clarification here explains a situation I had with an AF General. I wondered why I got 'that' look.
