I'm sad.
I saw this thread a few hours ago, and thought it would be a 10 reply thread, then die in obscurity. I'm saddened greatly that there can be any sort of debate about this.
It's WINDSPEED that enables lift. If the plane isn't moving relative to the wind, it ain't going up.
As a very correlate aside, planes take off into the wind. They also land into the wind.
So saddened.

I thought it was that simple when I first looked at it but it really is not. Nobody in this thread disputes that you need air flowing over the wings (forward movement) to create lift, (thank god).
The issues are whether the forward movement of the plane is prohibited by the conveyor belt, the original conditions of the problem, or neither.

Doesn't:

The runway moves in the opposite direction of the plane at the exact same speed as the plane's wheels.

mean no net movement? Same speed, opposite direction.
Bah, nm. I guess I could read the thread if I wanted to see what was causing the confusion.
