[QUOTE=Hell0;35890719]Millenium Prize Problem [IMG]http://i47.tinypic.com/2wem634.jpg[/IMG][/QUOTE] No, because it needs to gain momentum and if it was on a treadmill it wouldn't be moving.
[QUOTE=Hell0;35890719]Millenium Prize Problem [IMG]http://i47.tinypic.com/2wem634.jpg[/IMG][/QUOTE] i always wondered if something like this would work

[QUOTE=DChapsfield;35890938]Gimme the prize. Airplanes rely on the concept of airfoils. An airfoil is a design for an artificial wing which uses Bernoulli's principle to generate a lift force. That principle states that as the velocity of a gas increases, its pressure drops, and visa-versa. An airfoil is designed to have a greater length on the top of the wing, and a smaller length on the underside. This turns into the distance that the air moving under and over have to travel to move past the wing. The air moving over the wing has a greater length to travel in the same amount of time, necessitating an increase in speed. Knowing Bernoulli's principle, then, we figure that the increasing velocity of the air moving over the top of the wing will result in a localized pressure drop. This indicates a pressure difference, as the air moving underneath the wing has no change in velocity, and thus no change in pressure. Higher pressure underneath the wing -> lower pressure above the wing -> a force of lift, pushing the airfoil (and by extension the plane) upward. [B]The gist of this is,[/B] the plane and its airfoils needs to be [I]moving through the air.[/I] The plane would indeed eventually reach the speed at which [I]moving[/I] air would begin to lift it off the ground, but since their is no movement of the airfoils through the atmosphere, nothing would happen.

For fuck's sake, wheels on a plane don't provide its momentum, the engines do. if you assume there's no friction in the wheels, they'll spin pretty god damned fast while the engines thrust why did you draw me in to this pointless argument

[t]http://i.imgur.com/JQFHU.jpg[/t][/QUOTE] The huge flaw in your response is that you assume the plane accelerates by pushing off the ground. The treadmill does not move the air above it. The plane accelerates by pushing off the air with its engines, not by pushing off the ground. Provided the wheels are lubricated enough, the plane will accelerate (and take off) regardless of how fast the treadmill is going.
I find it extremely funny (and somewhat frustrating usually) whenever the Plane-On-Treadmill-problem comes up. It's a question masterfully designed to fool you into the wrong conclusion and stick to it. The correct answer is the plane WILL take of. The simple reason for this is that the treadmill can't push the plane backwards, because the landing gear wheels are free-spinning, so it WILL begin to move forwards and cause air to rush across the wings no matter how fast the treadmill is spinning (the treadmill does not push air). Mythbusters isn't science but they tested it: [video=youtube;0KsdMuhYJPw]http://www.youtube.com/watch?v=0KsdMuhYJPw[/video] Would a hovercraft on a treadmill be able to thrust forwards? Of course it would. Why? Because it is pushed forwards by thrust from its fan, and is separated from the moving treadmill by a cushion of air. The jet is pushed forwards by its engines, and is separated from the motion of the treadmill through it's free-spinning wheels. The jet will simply take off as if the treadmill wasn't there at all, because regardless of how fast the treadmill attempts to spin the wheels of the aircraft will just spin faster.
