How Aeroplanes Fly and Propellers Pull

Hi All,

A point of curiosity prompted this question in the Wannabes forum.

What is the primary factor that sends us aloft: Is it Bernoulli or Newton's Third Law? I actually took it as read that it was the former. But after reading Stick and Rudder and then thinking about aerfoils such as aerobatic symetrical sections or thin delta wing designs, I'm moved to believe that Newton's Third Law is the primary and possibly the overwhelming influence with the shape and camber doing little more than tweaking the efficiency of the wing.

That's enough of my semi-blind hypothesising. Are there any educated opinions out there?
