You might want to check on the accuracy of the oft-repeated /myth/ that
wings develop lift because of the pressure difference between the
upper and lower surfaces. My understanding of the physics is that
this component is negligible compared to the second mechanism you
mention of the downward deflection of the airflow.

If you think I am mistaken, then please explain how symmetrical
airfoils develop lift!

Amusing how partisans grow zealous for their chosen explanation! :-)
