Wiz, you may have commented while I was in the process of editing one of my numerous rewrites so that my comment made sense. I just remember how it was taught to me and I could never understand how air simply speeding up over the top surface of the wing created enough low pressure to lift an aircraft. Many of the diagrams at the time showed air in parallel paths moving aside to make way for a wing and then getting restored to order once the wing had passed. It wasn't until much, much later when I was "educated" that the air is moved downwards. It makes it a lot easier to understand many things about how the wing works.
