I dont think they are "ignoring" the thrust. I think they are confusing ground speed and air speed and how the engine thrust related to them.
I cant put it to bed until EVERYONE is on board.
will it take off?

A quote from the original question: "the conveyor has a system that tracks the speed of the plane and matches it"
I would still like someone to explain to me how the plane can sit still, yet the conveyor moves? Ive asked a few times in this thread and I dont think anyone has answered it.
I think this question needs to be answered if the "no flys" are to see the error of their ways.

Patrick G,
You have to get over the plane remains stationary idea. That is the trick. The problem needs to be revisited. "As the plane moves....." You are still thinking wheel speed. The convayor is matching the plane speed, not the wheels. This convayor does not require magic to match plane speed. It might to match WHEEL speed. I agree, All this talk of speed of light and wheel chalks are irrelevent. All you need is a convayor to move at 50 mi so the plane can perform in the oposite direction at 50 mi to lift off. The MCB does not need high acceleration either. The plane could slowly ramp up speed, but when it reaches lift off speed, she flys. So I don't get where magic is needed other than some having to build this contraption to show the non-believers they read the problem wrong. This whole silly puzzle could have been settled if the first point of matching wheel speed vs plane speed was settled.
Your point of the convayor catching enough wind to provide lift has little merit because the above points

Ray,
There have several of us who have asked the question of moving/not moving and speed of wheels vs speed of plane. No one address it. It always fall back to wheels spinning at infinite speeds

You can draw all the stick drawings you can produce and while you're at it throw in the grassy nole argument stick figures and the Jimmy Hoffa whereabout maps along with the 911 conspiricy instructions along with it. Patrick G is right. You all are confusing the argument. One more time.
If the planes mass (wings and all) does not expierence the forward movement and associated air to produce lift and the treadmill effectively nulls that forward thrust the plane is producing, then the plane is not going to become airborne. That mass (the plane) has to physically move thru the air to introduce all the properties required for lift. MYTH STILL BUSTED UNTIL I SEE IT IN PERSON!!!! Then I will buy all of you a happy meal if my wife says it's ok

Wheels spinning at infinate speed if the wheel speed is what the question means by "match the speed of the plane".
If the question actually means for the conveyor to match the speed of the whole plane, then the wheels will only be going twice as fast as takeoff speed and the conveyor would be going the same speed as the plane (as per the question)

Egon said:Now I am getting really confused!
I beleive someone indicated lift would created by air flowing over the wings.
Well, today I drove to Halifax and back with lots of air flowing over the right and left wings of my truck. Even at speeds in slight excess of the posted limit I did not notice any lift occuring.
I've gotta see a picture of this truck, maybe we can give you some insight on how large the wings will have to be to achieve liftoff.

Egon,
So.... your truck has wings?
