My dad served in the Air Force as ground crew for several years, and doesn't really talk about it. I know that it's there. I think my main thing about direct or indirect experiences as near to home as it were is the idea of self-sacrifice really.

He has such a patronizing tone and manner, and such a sarcastic sense of humor. I found him rather brutal, a kind of elegant brutality which appealed. No, I think he came pretty much off the page.
