I posted it earlier here. Since the airplane do not acquire forward momentum by friction against the ground, but by its motors, the answer is obviously yes.

Depends how fast you can make the conveyor go. And your explanation of the problem isn't correct with the answer you're going to give.

Care to go into more detail?  

But the answer is yes.

A mythbuster and straight dope explain that it will work for several reasons, namely that the conveyor lacks the speed to prevent the plane from moving forward. Lift is generated by moving the plane from a medium, in this case air. If there is no movement, there is no lift, and no lift, take off is impossible for a conventional plane. If you could build a conveyor that could produce enough speed to  keep the plane stationary, then the plane wouldn't be able to take off.

Actually if you had a conveyor moving faster then the plane, it would go backwards.
