I'm not going to try and argue any further. It's infact very simple. All engineers that I know also say that the plan will not take up.

remember,

1. Air plane thrust engine give it +X Velocity
2. Plane's weight give it -Y Velocity
3. Gravity weight adds to that -Y velocity
4. Treadmill gives enqual -X Velocity.

So, I will not trying to be precise, but instead be very simple about it, you have

X - 2Y = Plane's velocity
-X = Treadmill Velocity

Put them on the equation, you still end up with -2Y. You need Possitive Y to give it lifts. That above is not entirely correct equation since you'd have to factor in a lot more, however, it'll just yield extra -Y velocity, of which would further strengthen the concept.

X & Y are X-Y Axis of directionals

Anyone know physics can always tell this. I'm not saying I'm right since I'm also an engineer, but if a bunch of others senior engineers who said the same thing as I am, there must be a common.

I don't want to argue anymore if you don't understand. Have a good day.
Let's make it simple, the treadmill in no way what so ever will ever prevent the plane from moving forward...no matter what. Therefore gravity, lift, thrust, etc. everything is EXACTLY the same as if it were on a tarmac. Period.

Ask those same engineers if it's possible to drive into the back of a moving truck, just as KITT did in Knight Rider or the SSR does on it's commercial where it does a 180° onto the trailer...
