interesting argument.. (for the self proclaimed geniuses of IA)

I think that in essence the question is could you make the plane take off at a stand still. Which is no, you even stated the plane has to move forward.

exactly.

if 2 forces are equal and opposite they cancel each other out.

but the forces arent equal

explain how and i will agree, that is the only basis for my argument.

There are many more factors here than just the speed of the belt compared to the speed of the wheels on the plane: friction, thrust, weight. They all factor in. Also planes measure speed by how fast the air is moving, so the plane would have to physically move in order for the belt to start moving. Once the plane is moving, the friction on the tires is close to nothing compared to the thrust from the jet engine. The matchbox car example is a perfect example, the wheels on the plane will always be able to match that of the belt, and, in the matchbox situation, the hand pushes the car forward, much like a jet engine.

but the wheels do not push the plane.. they simply guide it.. I think it would still take off but then again.. I'm really no genius..

Exactly!!!

The WHEELS are the only means of drag. Does that make sense to you? ONLY the wheels. They spin freely.
