On the contrary, the problem clearly states that the conveyor is moving at
the speed that the plane is moving (but in the opposite direction).

The statement "the conveyor is moving at the speed that the plane is moving"
(the one you say the problem states) is a very different statement from
"which always reduces the plane's forward movement to zero" (the statement
Thomas responded to).

How is your post contrary to Thomas'?
