Yeah, the usual explanation of "air goes faster over the top because they have to meet at the end" is BS. Especially the 2nd part. A video about the subject htt

Yeah, the usual explanation of "air goes faster over the top because they have to meet at the end" is BS. Especially the 2nd part. A video about the subject https://www.youtube.com/watch?v=QKCK4lJLQHU https://www.youtube.com/watch?v=QKCK4lJLQHU But the explanation I can come up with is: lift is a force due to low-pressure regions caused by laminar flow over a surface. It is essentially "form drag" (caused not by the profile facing air directly but by the aft part) but the tricky part is that it is not directly parallel to the flow of air, but also depends on the orientation of the wing.
