Do you have to ask. It's such a stupid myth.

they tested it and it did take off right? I refuse to believe it can

It took off. In model planes and full scale, with no effort what so ever.

No. There needs to be air flow across the wings to generate lift.

If the treadmill is in a wind tunnel then yes it will take off because there will be airflow generating lift.

I am sure you are just saying that to get a response

If I threw a coin from my hand in to the air 500ft. Would it ever get there?

Yes, it took off without issues. Go to you tube and search for "mythbusters plane treadmill" or something similar. There are tons of other examples no doubt on the site too.

back to school...

What has the ground speed got anything to do with wind speed.

What powers a plane? clue it's not the wheels.

salami1212 · 3 Sep 2009 at 17:54

say if the plane was stationary on a treadmill, like people are when you run, would it then lift off or start hovering?

no.

But remember what powers an aircraft again the clue is it is not the wheels.

That is BS. The plane was moving forward before it took off. If it was still, in relation to the ground, it would have stayed put.

Why would it stay still. What powers an aircraft.

No, the wheels are just free to do as they please. Because of this the plane is pulled forward by the force of the propellers, which drive the wheels.

How do you think a sea plane takes off, lets say that the sea plane wants to take off to the north, and the sea is pushing it south, the plane just glides across the water and takes off.

so theres 2 outcomes depending on if the plane is moving forward first

No. if the engines are on it will take off. The wheels are just free rolling they are unpowered.

God how is this so hard and how can you think like this.

I was gob smacked they even did this on mythbusters.

The engines provide forward thrust. Once the plane has gained enough speed on the runway, the wings will provide positive lift and it will take off.

The plane is clearly moving forward in the mythbusters episode, this gave it enough airflow across the wings for it to take off. If it's position was stationary in relation to the ground, it would stay still.
