Up to a max altitude of 7 meters (at best), sure, an Ekranoplan has got all the degrees of freedom that other aircraft have, Which as was pointed out here https://news.ycombinator.com/item?id=24629545 https://news.ycombinator.com/item?id=24629545 , is not 6 Imho no, an Ekranoplan does not fly freely. Nothing to do with a bogus DOF count though

  > Nothing to do with a bogus DOF count though 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.

    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.

  The only reason an Ekranoplan can't fly higher is it's wings don't generate enough lift out of ground effect. Load a 747 up high enough, and it too wouldn't be able to get out of ground effect, but I'd still say it was flying.

    You can't just say that "because it's a 747, it can fly": A 747 with no fuel can't take off and fly. A 747 with so much load that it never takes off at all, can't fly. And IMHO, a 747 with just so much load that it can barely take off but can't get out of ground effect, also can't fly. It's borderline, but not really. It's an academic distinction though. Give the 747 a while, and it will burn enough fuel to lighten and ascend.
