Maybe I'll stick with Bernouiliis' Theorem after all..it's getting far too complicated here....
Seriously, though, I've been amazed at the response this thread has received...obviously, not everyone agrees on how a wing works, or what is the best explanation of how it does. It's been very interesting, and I've now got loads of reading to do....thanks!
As far as only teaching Bernouilli to students, I still think they should be taught the Newtonian theory, even if it is more difficult to explain, which I don't think it is.
Or perhaps, if pilots are not 100% sure what's keeping their aircraft in the sky, they will plummet earthwards.......maybe wings only fly because we think they can....
