remember this is the physics section... I only want what makes it possible. The structure responcible for the flight. I don't care about propultion or flaps, how a plane is controlled. I only want the most simple thing, that which makes it possible.

Oh, and a bird flies by downward thrust, nothing like the physics behind what makes a plane fly.
