I guess I'm confused. If an aircraft can't go backwards or do a loop, does that mean it's not flying? Because as far as I know, every fixed wing aircraft is incapable of going in reverse, and most can't do a loop. Not trying to pick on your defenition of flight based on degrees of freedom, but that doesn't seem to match any definition of flight I've run across.
It seems that you don't understand the implication of the DOF count. Flying means moving freely through the air. That, colloquially, means 6degree of freedom movement through space. It means looping a, it means barrel rolls, it means it can run circles and go backwards and move upside down. You know, flying.
Ekranoplans fly as much as an hovercraft does, which mean they don't. Case in point: they are unable to do 6dof movement. An ekranoplan doesn't do barrel rolls for example.
