If a sail on ship produces 'lift', why are aircraft wings not made the same with billowing sheets of material?

Save that, just thought hang glider..duh.

Don't forget Britten-Norman put the theory of Acoustic Lift Technology into practice....

Design documents clandestinely recovered from the Britten-Norman shredder have solved a question that has puzzled aerodynamicists and pilots for many years, disclosing that it is actually noise which causes the BN-2 to fly. The vibration set up by the engines and amplified by the airframe, in turn causes the air molecules above the wing to oscillate at atomic frequency, reducing their density and causing lift. This can be demonstrated by sudden closure of the throttles, which causes the aircraft to fall from the sky. As a result, lift is proportional to noise rather than speed, explaining amongst other things the aircraft's remarkable takeoff performance.

After being a professor and teaching lectures on the dynamics of compressible and incompressible media and meteorology for over 30 years, I am wondering, who believes theoretical knowledge makes a better pilot?

I have seen many great intuitive pilots, which were absolutely lousy students. I also regret to have let pass quite some great theoretical buttheads, which became the lousiest pilots ever.

There are certain parts of theory, I believe make a better pilot, if the physics and chemistry is well understood. One most prominent example is weather. If you understand the complex system of weather, it gives you opportunities for great piloting. But, apart from the very basics of lift and flying, I now believe it is much more important to focus on other things. Maybe I am getting too old, but there is not much into from the theory of flying you really need to practice flying. Or are the younger ones already overwhelmed by the simplest things?

I teach that air being a fluid has viscosity and it is that property which instills a want of the air above and below the wing to meet up at the trailing edge, however never do.
As some mentioned the basics are more important as in how can i make this aerofoil work better and what will make it worse, what will happen when I do this.
my 2cents
