This thread rocks,
The conveyor is moot,
Tacos are a great idea,
And ...
The plane will take off.

Dad: we had this discussion on the other thread.
Ugh, if I had time to waste I'd go to the airport and prove it. Here's how I'd do it.
I'd find the speed of the terminal walkway conveyors. We'll say 5mph.
I'd superglue and industrial fan to a skateboard. I would add weight to the system until the skateboard moves under the propulsion from the fan at a speed of 5mph.
I would put the skateboard on the conveyor, and turn on the fan. So your -5 mph from the conveyor, and the speed from the fan mimicing the turbines. The skateboard will move forward, it will NOT stay put.
Then I'd upload the video and be done with it.
Somebody please do this.

What gets a plane moving are its propellers or jet turbines, which shove the air backward and thereby impel the plane forward. What the wheels, conveyor belt, etc, are up to is largely irrelevant. Let me repeat: Once the pilot fires up the engines, the plane moves forward at pretty much the usual speed relative to the ground--and more importantly the air--regardless of how fast the conveyor belt is moving backward. This generates lift on the wings, and the plane takes off. All the conveyor belt does is, as you correctly conclude, make the plane's wheels spin madly.

Not if the treadmill simultaneously speeds up in the opposite direction.
