Flying Saucers

Why are flying saucers always portrayed as bi-convex shapes? Saucers are convex on one side and concave on the other. There has got to be some sort of nameological word for a bi-convex round shape.

And there's got to be a better word than nameological. Perhaps some derivative of taxonomy. Yeah, I think I'll stick with taxonomical. I have no idea if that's even a word. Firefox seems to think it isn't.

(I'm watching something about the Bermuda Triangle right now)

And apparently "Cay" is pronounced "key". I didn't know that.

And another thing I'm discovering from this is that World War II era planes are attractive.
