I'm sympathetic to those who have to close one eye to be sympathetic to DUIs when it comes to aviation-appliance-operation. Just don't do it. Basic common sense. Etc. etc.
That said, I've seen at least two people absolutely rat-screwed by supposedly having (other, non-aviation, to be clear) crimes "expunged" and then discovering that while their plea said "expunged", they weren't *reallllllly* expunged. Like, that was just to get them to sign on the dotted plea-line. And as a question separate (and I would argue greater) than/from one's driving record, that's monstrously nasty, sneaky, and unfair.
