Yeah.. so most people know that I am a student who absloutely hates the book work of physics, but gets what is going on in the experiements.

I'm gonna switch to common sense, or lack their of in this analogy, and say that since Plane (A) is "accelerating" in a positive direction, and Conveyer belt (B) is "accelerating" in a negative direction based on Plane (A) then in all essence the plane is not moving (linearly) at all on this conveyer belt and the plane will not take off.

A = +X speed
B = -X speed

They cancel each other out, and there is no linear displacement.

And my physics training will say that distance (or the X amount of miles the plane is racking up spinning it's wheels on the conveyor belt, does not equal the displacement required to take off.

For example:
What would happen if you put a car on a dyno machine.. It accelerates, and adds up milage, but it's not going anywhere.. (as long as your dyno doesn't fail and freeze up) lol

And yes, I know cars and airplanes are not created equally, but I'm just sayin' - It's the same kind of setup.
