omfg not this again
Yes!
Mythbusters proved it

Not with that apple in the way!
Are there any motherfucking snakes on the motherfucking plane?

is this an argument about wether a plane would take off from stationary with the wheels spining only by way of conveyor belt?

a plane would take off with no wheels if air was forced over the wings quick enough

Thats not the physical limitation of the experiment.
An aeroplanes wheels are not motorised so the conveyor could spin at 1000mph and as long as the thrust of the engine was greater than the drag the wheels create (pretty easy as the wheels create little to no friction) then the plane will still accelerate and take off.
However, if the plane was held in situe by a big brake so it could gather no momentum then it wouldnt be able to take off as the lift a plane needs is created by air passing over the wings. The propellor or jet simply provide the forwards thrust needed to get the required speed up - they are not fans that blow air over the wings

And whats your point? the experiment is a plane taking off on a conveyor belt, not a plane tied to the spot - that's a whole different concept.

The truck moving one way matched the speed of the plane, it will still move forward no matter what. A plane stationary on a moving conveyor belt wouldn't take off in a million years.

Why would a plane be on a conveyor belt anyway

Maybe it's giving it's little wheels a rest

The confusion arises because there are two states in question:
1. The equilibrium at which the thrust from the engine equals the frictional losses from the wheels. In this state, the plane would be stationary with respect to the air around it. Note, this is a very, very low level of thrust. The wheels are designed to have a little friction as possible, and there planes engine would have no problem whatsoever overcoming this.
2. The point at which the engine thrust overcomes the frictional loss on the wheels. This would allow the plane to take off exactly as if it were on normal ground. The plane would proceed forward and generate lift by way of air moving over the wings. Exactly as normal. Except the wheels would be spinning twice as fast. Which as they're designed to spin may mean they get a bit hotter than their design dictates. But the airspeed would still be available and therefore the plane would be able to leave the ground.
