... Forgive me if this has been covered (been 'by-passed't this past 10 days) but fly or not, it is all about the relative AIRspeed...over the wings. With the pilot accelerating .... and we notice the ASI increasing... regardless of the wheels spinning a lot faster than normal and the ground moving under him.... the airplane must obey its Laws of Flight and eventuallty respond to sufficient airspeed.
And fly.
We can illustrate this with a downwind landing... you are flying at just above stall speed-inside the lump of air - which lump is travelling down the runway in the same direction. - And boy, is the world going past you at a blurring rate of knots. !!!

If engine and air-surfaces are intelligently manipulated by a skilled pilot, the previously parked aircraft 'should' leave the ground and assume a suitable nose up attitude and climb out....whilst moving backwards from its original parking point. - Which is what toy kite will do, the string holding it in place to allow the wind to lift it. In this case, the engine can be called the 'string'.

But agree, a great inclusion into Human Factors...

I am guessing you are either trolling (as suggested previously) or haven't watched the videos that show that it works.

And fly.

I think only one person is disagreeing with you ...and it's not me.

I have also watched model aeroplanes just hanging vertically on their propellor.

That doesn't prove that a GA aeroplane can do it.

Have you read any of the posts that explain why the plane will fly?

Have you read any of the linked articles such as the one in post #92 that explain why the plane will fly?

Do you have any intention of addressing the specific points that anyone has presented that clearly show that the plane will fly?

Have you read the questions in post #64? Do you have any intention of answering them? It might help us to understand why you are persisting with your opinion.

Simply repeating that the plane won't take off does not constitute an explanation.
