Mythbusters will finally test...
Plane on a conveyor belt!!
http://mythbusters-wiki.discovery.co...otos%21?t=anon
So, a poll. Plausible, confirmed, or busted?
I'll make the poll public too

They are seeing if a plane can take off after staying put on a treadmill? Am I right?

Yeah, the myth is will an airplane that is on a conveyor belt moving backwards be able to take off.

EDIT: Hmmm, the myth is a little different than what I thought, rendering my prediction useless.
Originally I thought the treadmill was going forward and the plane was sitting stationary on the treadmill moving forward as fast as the treadmill would take it. I would guess the plane would take off just fine as long as the treadmill was fast enough. Sorta like on an aircraft carrier.
For what the myth actually is (plane moves forward as treadmill moves backwards), I'm not so sure. The plane itself would still be stationary regardless of how fast the treadmill was moving backwards. I'm no scientist but I say this one gets busted... would be cool if it actually worked though.

It doesn't matter what the plane's ground speed is other than scheduling. It's all about air speed.
Which is why major airports have runways going in different directions, so planes can take off into the wind.

If the wheels of the plane are on the belt. As the plane picks up speed, it should stay stationary. The air will not flow over the wings in order to provide lift, therefore it will not take off.

Going by the poll it is wether or not the plane will take off.
Even if it works, a major safety hazard.
Imagine sitting on the plane enjoying the lovely pre-flight safety instructions. And then all of the sudden you lurch forward because your plane which was getting up to 400 mph was on a treadmill broke, meaning there is solid ground beneath you, and your plane catching traction and takes you right into a brick wall.
So I guess my only question is about the length of said conveyor belt. If the purpose is to shorten the runway, then its plausible, but if its plane lengthed. It wont work

Yeah, exactly... is this even an actual myth? Who believes this?
I could be a writer for this show if we get to debunk things already widely known to be untrue/not possible!

Thats rediculous.. Its impossible if they are going to test it with the plane remaining stationary..

Who said the plane is going to remain stationary?

Oh- I see.
It will go the opposite direction of how we normally use a treadmill then? ie standing still in relation to the treadmill?

The wheels are free-spinning, the amount of force they'll contribute by friction would be minimal (that's the whole point of landing gear wheels )

No, the belt goes in the opposite direction as when we use a treadmill.
Plane goes this way --->

Belt goes this way <-----

No way this works. All the treadmill will do is increase the wheel speed of the landing gear. The plan will stay stationary.

It would work then... Similar to a glider being winched in the air.. If they locked the wheel of the plane and the treadmill slowly gained speed it should work..
