(So Focal, you reckon that anyone operating a quad is an idiot as well, then, do you? Twins have their place, as do quads - let's just face it. Want to be free of ETOPS constraints? A quad is your only option.)
There was nothing wrong with the DC10/MD11 Tri-Jet, perhaps one of the finest commercial aeroplanes ever built, but then a decision was taken to cease it's production so as not to compete with Boeing's twins.
It would seem the customers were not given a choice, you take a twin or nothing, after all, only idiots manufacture aeroplanes with more than 2 engines!
