You already answered, eh?!

Ok smarty...will a 620 Capirex do 140 mph?

Too bad I already answered it.

I bet you can do an atomic situp without any effort.

Yes it will take off, and the reason why is because the airplane's wheels just roll free, the propeller is what makes the plane go therefore, the plane will take off regardless.

Dude-there's no lift.

I'm 100% that there would be take off.

the thrust of the engine will move the plane forward getting the leading edge of the wing to lift-off speed

irrespective of what the wheels are doing or how fast they are spinning due to any opposing speed conveyor belt

the critical relationship is between the airframe, the engine creating thrust and the air

did someone have a problem wrapping their brain around that?

hmm

Drunkeness has prompted me to be here.

Because lord knows I want to stay away.

*sigh*

What causes planes to fly? Lift. How do we get lift? Airflow over/around wing (and/or any other "lifting surface") surfaces. What does a convener belt not provide, no matter how much thrust is applied to the airframe?

Mythbusters - Plane on a Conveyor Belt

Oh please not this again. 

I vote for Boobies!

regardless of how fast the conveyor belt is moving, the plane will not stay on it.  The propeller or jet is pushing against the ambient air, not the speed of the belt.  The wheels rotate freely.  Once the plane is free of the belt, which may take a little longer than rolling away from a surface that is stationary, if there is enough room, it will roll forward and take off normally.

A plane is standing on a runway that can move (some sort of conveyer belt). The plane moves in one direction, while the conveyer moves in the opposite direction. This conveyer has a control system that tracks the plane speed and tunes the speed of the conveyer to be exactly the same (but in the opposite direction). Can the plane take off?"

You really did this again...? oh Bob

Ok, maybe I'll divert this train wreck...

If you push an object out of the back of a moving vehicle at the exact same speed, but opposite direction as the vehicle is travelling how will that object fall?

Down.

More precisely?
