If you will be satisfied with empirical evidence, stick your hand out
the window of the car while going 50-60 MPH. Experiment with
different angles of attack. You will no doubt experience lift when
your hand has a positive angle of attack. Poor man's wind tunnel -
but illustrates that just about anything relatively flat will fly
given enough speed and a positive angle of attack.

That's why wings have camber. 'Cause they don't need 'em.

Bertie's a shill for the Alcoa Camber Conspiracy. ...they've sold
more metal by convincing every successful aircraft designer and
manufacturer in the history of aviation that upper camber is
necessary, when all they need are two simple deflection plates.


Yeah, that's it. Also, I get good money from the guys who deice aircraft
upper surfaces..

Fortunately, the wizards at sci.physics have busted the conspiracy and
we all see now how the designers of all aircraft were grievously
wrong.


It had to end for me sometime. ;(

Well, I had a good run..
