Alright....there have been a lot of complex definitions on here, and I agree with most all of them. But the easiest way of explaining this is just how MikeL put it when he said "it's the thrust of the engine that provides the lift and airflow over the control surfaces. "

Basically, 3d takes an engine with a lot of power so that the engine is what is holding the plane up....not the wing. That is what all of these guys are saying basically.
