Starting with the basics...I wonder if PHAK's explanation of lift generation is correct. It has been a lot of debate on this topic, and the one used by PHAK seemed to be proven wrong by NASA. Up to this moment, I find the one considering airflow to be circular motion most accurate and acceptable...How do you guys think?
