YES! The plane still moves with respect to the air and with respect to the earth's surface.
If you are saying that to an outside observer looking upon the conveyor belt scenario that it would appear like a normal takeoff from start to finish relative from their viewpoint ... then there is a big problem with your perception of this entire discussion.

Your perception of it doesn't seem to be including the fact that the conveyor and the plane's speed have been matched exactly.

Once the conveyor and the plane's speed has been matched, the outside observer will see the plane as standing still whether it is or not.

Do you understand that fact?[/b]
Not true. I answered this on like page 4 or somethin'.

OK, top of page 7:

Hypothetical scenario:

t = 0 :

Plane 0 mph
Conveyor 0 mph
Wheels 0 mph

t = 15 :

Plane 60 mph
Conveyor 60 mph
Wheels spin @ 120 mph

t = 55:

Plane 160 mph
Conveyor 160 mph
Wheels spin @ 320 mph

Plane takes off!!
You are confusing the motion of the belt with force. It exerts virtually no force on the plane due to the wheels, which spin freely.

EDIT:

Please take a really close look at wheelspeed before you reply...
