"Carry on Sergeant" has been getting officers promoted for centuries.
I knew
Bob Todd (17th) and
Ken Porter (147th) tolerably well and was acquainted with
Ray Brooks (22nd). If you'd asked me in the 1980s, I would've bet cash money that Ken would be the last WW I ace standing, but he faded in the stretch. Bob and Ken did not get along--we never knew why. I do not think they ever met during the GW, so it must've been something that one or t'other did/said at an aces reunion.
Ken coined one of my very-very favorite sayings: "If you find yourself in a fair fight, you really fouled up." Though he didn't say "fouled."
Ray was a sweet old gentlemen--absolutely charmed the wives of the WW II aces. He used to say "I'm Ray Brooks, or what's left of him." He could absorb a lot of maternal attention.
