Ignore the wheels, thrust is created by the engine turbines/propellers, the thrust acts on the environment. The wheels simply turn in response to that thrust and being in contact with the treadmill.

Obviously this isn't a serious question...
Everyone knows that it needs sufficient airspeed to have any chance of lifting. It's a low pressure area above the wings that create lift, which is created by faster airflow over the top of the wings.
The engine thrust on its own won't do anything if the airspeed is 0, or too low. The engines are the ones creating the airspeed.

Seriously! And you guys mock Zuma & Julius. What school did you attend? Call your science teacher and listen to his/her sobs on the phone while you spew this bs.

Please explain how a plane can fly if the wheels are what drive it forward?
Oh my word! Read the nonsense you're typing please!!

Exactly! If the treadmill stops the plane moving, that means that it's the wheels doing the pushing!
You aren't doing yourself any favours here... Care to explain how the following two planes manage to take off, no wheels involved...
I agree, only if we are talking about a RAF harrier jump jet which can direct its thrust in the z direction. As far as I am concerned the turbines in question only act in the x direction. I am focusing on the wheels as it is the key in this argument. Plane is standing still = 0 lift/z force. You are going to remain on the ground.

OK, let's say the engines are providing thrust of 1000N along the x axis
You say the treadmill is countering that thrust? How? How is it exerting 1000N of force on the plane?

Only way to explain your logic bud. Seriously.
My goodness it has nothing to do with wheels(the jet engine provides the thrust those wheels roll freely) its about movement. You need movement(through air) for lift. All those planes move forward right? If this silly treadmill idea keeps the plane in one spot its not going to lift. If the plane moves off the treadmill and down the road then it will fly.
If you have a massive fan that can move air over and under the wings sure then i suppose the plane can remain in one spot. But guys you need thrust and lift!
You guys are straight up dumb

How does the treadmill affect the thrust being generated, how is it possible for a treadmill to counteract the force of those engines?
You can do this yourself, get a toy truck and hold it in place on a treadmill, the wheels will spin at the rate of belt. Now push the toy truck forward using your hand.. by your logic this is impossible but you know it can be done, the toy truck wheels will spin more than the rate of the belt and you will be able to move the truck forward. In this scenario, the force of the engines is doing exactly the same job as your hand.

HOW WILL THE ****ING TREADMILL KEEP THE PLANE IN ONE SPOT?!

:crylaugh: After your post, you're criticising MY logic? Now I've seen it all.
That won't happen, it will still move forward despite being on the treadmill.
There are some videos earlier in the thread showing this happening.

That tends to be difficult for some
