Ok use a kite as an example then. As long as you hold the rope and there is some wind, up she goes. I would be willing to accept that even a kite is not a very good thought experiment though, because all lift is a mix of Newton and bernoulli and you cannot separate them out so easily. This may be why so few people understand lift. You really need to work with a variety of airfoils under a variety of conditions to understand. For example, smoke tunnels show air flow, airfoil codes show pressure distribution, and in both you need to change angle of attack, airspeed, and airfoil shape to get an understanding of what goes on. This plus a ton of theory helps. There is a basic discussion in Pilots Handbook of Aeronautical Knowledge (PHAK) on lift. Somebody needs to send it to NPR.
