The Guppy flies just fine and I'd be happy to teach you how it can

learn all about how airplanes can fly such as Bernoulli's principle,
Newton's laws of physics etc. Interesting stuff!



Stop abusing Bernoulli!

Uh oh....here we go again with the ol' Bernoulli vs. Newton debate.
If I were teaching a newbie (like sergeant dan who loves to argue
just for the sheer sake of arguing because he has nothing better
to do with his miserable life) I'd have to simply explain to him that
BOTH Newton and Bernoulli are important. Sure, the links you
provided above (BTW, good website I refer to it often myself) show
that airplanes can fly with the "Bernoulli side" down, however, like
I said both Bernoulli AND Newton are important when it
comes to explaining how subsonic airfoils create lift.



Stop abusing Newton, too!

I really wasn't trying to start a Newton v Bernoulli debate. Actually,
I think that trying to use either of them to describe lift is a bit like
the 3 blind men trying to describe the elephant.

I need to figure out a way to write a "circulation theory of lift for
dummies" book. The websites I referred to are a bit more like
"circulation theory of lift for those who have a somewhat better than
layperson understanding of fluid dynamics."
