Two years ago when I was in college I used to read science journals for
fun... One particular, just published within the past two years
(spring '04?) caught me.
It discussed the Bernuolli theory of flight- and (if I recall) quite
conclusively proved that one of the _fundamental_ assumptions of the
Bernuolli theory- that air that travels path over the top of the wing
is flowing appreciably faster than air that flows over the bottom- is
simply incorrect in a compressible fluid....
Obviously, you should take this with a grain of salt because A- this is
my first post on this board and B- I can't remember either the journal
or the exact date... but take it for what its worth
