Ground effect ain't exist anymore when the plane's altitude is getting a bit higher. It will land back.
Yes, that's why it's called "ground" effect.

Is it not demonstrated that a true flying machine, self-raising, self-sustaining, self-propelling, is physically impossible?
Joseph LeConte, November 1888

I can state flatly that heavier than air flying machines are impossible.
Lord Kelvin, 1895

I have not the smallest molecule of faith in aerial navigation other than ballooning, or of the expectation of good results from any of the trials we heard of. So you will understand that I would not care to be a member of the Aeronautical Society.
Lord Kelvin, 1896

The demonstration that no possible combination of known substances, known forms of machinery and known forms of force, can be united in a practical machine by which men shall fly along distances through the air, seems to the writer as complete as it is possible for the demonstration to be.
Simon Newcomb, 1900

Yes, that's why it's called "ground" effect.

Then what causes a lift?
Lower pressure above the airfoil and higher pressure below the airfoil.  Ground effect is a zone where the high pressure below the airfoil is enhanced meaning that a smaller airfoil is needed to generate lift.

"Isn't that enough?  What more do you need?"

>> No more. At least I already know that Bernoulli's principle is still 'valid' for some people, especially in aeronautics.

That's supposed to not happen, because aeronautics actually need not Bernoulli principle.

Bernoulli's principle applies to fluid dynamics.  Air is a fluid.  Sounds like Bernoulli's principle apples to aeronautics, whether they "need" it or not.

If something can fall, that is not necessarily connected to gravity.

If something can fly, that is not necessarily connected to Bernoulli's principle.

I personally still don't get what Bernoulli's principle means.
The explanation is like most other subjects in physics: confusing.

If you don't understand it or how it works, how do you know it's not needed?

Don't you think that you should have figured out what Bernoulli's principle means before starting a thread dismissing it?

Maybe this will help:

There are 12 versions of lift theory.
Even some years ago NASA has debunked such mainstream theory that has been taught at schools as well as pilot training centers.

The experiment contain evidence. But it needs a careful diagnose to interprete it.
I don't think the pressure on upperneath of the paper is lesser than the underneath of the paper. The blowing its itself is a pressure, the bigger one.

Then why don't you make your own wind tunnel and conduct your own investigation?
