I remember seeing one at the Paris flight show when I was a kid. It looked like nothing else. You'd think it was a fighter jet, except it's so massive and streamlined, it's more like a misplaced, oversized prop from a sci-fi flick. Absolutely amazing aircraft. Anybody has a list of other "odd" planes? I know about the giant Soviet plane, the Kalinin K-7 [1], though while being "special" it's not particularly elegant and never went beyond the prototype stage.
