there is no way to take off without wind passing over and under the wing...thus producing lift. If there isn't any wind in ones face while running on a regular treadmill, then there isn't any wind going around the wing, the airplane, or even a speck of dust on the goddamn plane. Because of the lack of airflow, there can be, and will never be, no matter how hard you try, whine and moan and bitch about it, any lift whatsoever and thus flight is impossible.
If the treadmill is only slightly longer than the plane(which I believe the myth implies) then it can't gain enough speed to create lift. The treadmill would have to be as long as a normal runway.
most people call this sort of instance a miscommunication, i did not fully understand the concept of this video, i am sure all of our questions will be answered tomorrow (1/30/08) at 9:00pm EST on the discovery channel when the mythbusters will attempt whatever this movie is trying to show.
The body of the plane has to get enough air speed to lift. The wheels dont matter at all. They are just so the plane isnt scraping its belly on the ground as it picks up speed.
the runway length is the same... doesnt matter if theres a treadmill or not.... only the wheels spin twice as fast with the treadmill.... so u DONT NEED A SHORTER RUNWAY
oh, man. that was FUNNNNNNNY! it flipped, just like this question has flipped out people's heads.
the debate at physorg. com's forum has to be the best. some guy won't leave it alone, it's hilarious. over 500 pages of back and forth between physics geeks.
mind you, the correct answer(double speed of belt/wheels compared to plane's forward motion) is on the first page of the thread.
Funny, this video actually did change my opinion. I think this entire debate is fueled by mis-communication. I thought the argument was that due to the treadmill, the plane would be stationary. Now I see what you're saying: The plane's thrust would still cause it to move forward, just with the wheels spinning 2x as fast as a result, of course. Ok, I'm a retard...
What the Heck? It's the wind moving over a plane's wings that allows it to fly. If it's staying in one place on the conveyor belt, there's no way it can fly.
but it wont be in one place, it will move forwards. The wheels on a plane free wheel, they do not drive it forwards, the 500t of thrust do the driving. The belt moving backwards has nothign to do with it. all the runway does is hold the plane up whilst its on the ground, its sill pushed by the jets, and it will still move forwards, the wheels will just spin faster. it would take of.
But the wheels have to spin faster then the treadmill is moving to propel it forwards...unless it lifts off the treadmill.
It's like you are running 5 miles an hour on a treadmill going 5 miles an hour...therefore you stay on the treadmill. If you go faster then 5 mph you move forward...
People saying it won't fly argue the treadmill always goes the same speed as the plane...so it can only remain stationary thus no lift, thus it doesn't take off.
? i don get it...

ur all stupid its possible for clean liftoff because there is wind because the planes movement isnt relative to the ground

Jesus christ people...
we all know air moving over an airfoil creates lift. the question is can the treadmill hold the plane in one spot. the answer is no.

Jbdranger, do you understand what the video is trying to illustrate? You apparently dont.
A treadmill cannot hold an airplane in place like it would a car or human.

Questions answered. Treadmill can't hold plane in place so plane will take off.

of course it can, but the real myth is saying that a plane pushes on the ground, when it really pulls on the air.

if a plane can be run on a belt, it would only need a distance of a runway that is 3 yards longer than the plane

FYI the treadmill doesn't matter a thing in this because airplanes have freely spinning wheels.

Only way I could show that the "runway" was actually moving in the opposite direction. Plus it made the plane do a flip
