What if we strap a jet engine to the roof of the car?
Will the jet engine be able to move the car forwards?
the jets help but since there is no wind going under the wings I dont see how it will attain lift off. When a plan moves the air moves under it's wings at an increasing rate and without that wind to provide additional lift it will stay on the ground. With really powerful jets angled towards the ground a bit more it may be possible but as it stands the plane would not take off.

What will stop the plane from moving forwards? The only thing it can possibly be is the friction in the wheel bearings, which is negligible.
There is essentially nothing to stop the plane from moving.

Except the treadmill matching the speed of the wheels. That prevents it from moving.
You keep trying to sidestep the bounds of the problem and ignore the very real force acting against the plane.
I say again - the plane will move backwards with no thrust applied. Speed up the treadmill and the plane moves backwards faster with no thrust applied. That right there proves what everybody is forgetting. Sure it's very small, but it's there.
Now match the speed of the treadmill to the speed of the wheels identically and by the very definition of the question it cannot advance no matter how much force you apply.

MasonLuke is a troll, ignore him. IIRC, he has been banned in the past because of his posts in a thread on this topic. You're not going to get anywhere with him. Logic, reason and physics will get you nowhere.
Don't bother with most of these people... if they don't get it after two or three explanations, they're not ever going to accept reality. Take smack down for instance - he knows the outcome of on Mythbusters is not going to match his opinion, so he tried to discredit it before the show even started.
There are plenty of very valid analogies that you can test yourself - the suitcase on a moving walkway is a good one. Rollerblades + rope on a treadmill is an excellent analogy. If people close their mind to reality, you won't get anywhere with them.

what's the suitcase one? don't think i've heard that.
