I don't that when we say 'dumb' we are referring to your intellectual ability. We're talking about knowledge of travel and air travel especially. At least I am.

You don't see too many questions like "I saw a United plane in Los Angeles last week. I didn't know they flew there. Where was the plane going?" on FlyerTalk, but I've seen that on Airliners.Net.

I don't care what you got on the SAT or what your IQ is; I am talking about knowledge of air travel.
