I was thinking about this the other day when I was way in the back of a DC-9 and the last windows are blocked off.

I tend to get aisle seats, and I'm not a big window-gaper; usually, there's not much to see but clouds or darkness. But would you feel comfortable on a plane with no windows?

Paratroopers and other military types routinely travel in a/c with no windows, but I think the general public would feel a bit uneasy about the whole thing. I believe I would, too. Would you?
