I know little of this, But I thought in ordinary flight it's Mr Newton=20
the opposite and equal force caused by deflecting the airflow. Even a=20
flat wafer will work (poorly). Nice Aerodynamic stuff reduces drag,=20
turbulence and such I thought? Same as Sail advances on boats?

But an ekranoplane, Ground effect Aircraft may be using Bernoulli=20
effects. Like a giant bloated disk head. :-) Certainly not working like=20
a hovercraft, hydrofoil or regular plane.

Military value may be close to zero as a Transport if it's spotted.
