Here's a good article, with even better links, explaining why those of us who are not aero engineers get a headache trying to mesh Newton's theories with Bournoulli's when talking about lift. I wish I'd seen this a few years ago. It would have been useful when my or some fellow JO's aero-related AOM training lecture dissolved into a long wardroom argument between the two camps. http://www.planeandpilotmag.com/content/2006/july/lifts.html
