NO, IT WOULD NOT TAKE OFF. THERE IS NO LIFT.

The only reason there is any dispute on this among people with half a brain is because they're making the same mistake I did, assuming this experiment actually had a point and that the plane takes off from an extremely short conveyor belt runway. The theory is simply a plane attempting takeoff from a conveyor belt the length and size of a runway will be successful. It is really quite simple. As long as the plane is able to apply its weight to the ground with minimal friction while it achieves lift, it will takeoff. The wheels spinning faster don't effect anything significant.
 
Of course the damn treadmill wont take off! it does not have wings and can't fly! DUH! how can anyone think it would? frickin idiots!
 
That would be really cool to see... so did mythbusters do some scaled down model demonstration to prove/disprove this theory?

Jesus Christ did anyone here TAKE physics?

this reminds me of the thread asking which bullet would hit the ground first, the one fired from a gun parallel to the surface or the one dropped from the same height. first came the people who were just wrong, then the ones who had paid attention in high school physics, then the ones who were more advanced and said that the curvature of the earth would affect it.

VTOL FTW 😉

Again, folks, the wheels need to merely be able to freely roll at twice the speed of a normal takeoff. 140 MPH for a prop plane, and about 280 MPH for a jet.

They can EASILY do this. Therefore the plane will have no problem gaining forward momentum realtive to the AIR, and thus enough lift to take off.

You are assuming the wheels are powering the plane. They simply spin to minimize the friction while the plane is applying its weight to the ground during takeoff. In this case they would spin twice as fast but the plane's engines are using the air, not the ground, to actually push the plane forward.

This is assuming the problem is stated the following way: "If the conveyer belt exactly matches the speed the wheels are turning, will the plane take off?"

Actually, that is rather stupid.

Again, lift is achived because ground speed is irellevant. AIR speed matters. And a plane gains momentum by pushing air behind it. The wheels merely reduce friction.

Therefore the plane will easily overcome the treadmill, gain speed relative to the air and thus obtain lift.
