And, I've read over the decades a number of reports from amateur astronomers seeing such craft.

But for me . . . that's a nonissue given my relative working around them on a daily basis.

I can speak only for my own (lack of) experience ... but again, I'm on of those dreaded Roamin' Cat'liks ... so apparently "under-represented" in UFO stuff.

Unless, of course, my odoriferous little friends were really from "elsewhere".

BTW, could you clarify a point? You write:

working around them on a daily basis.

What are "them"?

1) Flying saucers.
2) Flying saucer pilots.
3) Folks who claim to have seen flying saucers.
4) Folks who claim to have met flying saucer pilots.
5) Something else.

As another aside, IMO any cited authority is subject to challenge, and extraordinary claims require extraordinary evidence in support.
