Re: Physics of Flight (and Anderson/Eberhardt)

While I have personally just dropped the topic from my syllabus
(unfortunately FLUIDS in general seem to be a casualty of the 'less is more'
movement), when I did include the topic I included both effects. I haven't
had students do calculations for many years (and then they were Bernoulli
back-of-chapter calcs) so I have no sense of the proper mix of pressure
versus delta-p, and take it from the BDA discussions that this _simple_ view
is fundamentally flawed anyway.

So if there is an ultimate question in all this, it is: What (if any) is
the 10-15 minute discussion that can adequately convey the essence of flight
to introductory physics students (even those in purely conceptual level
courses)?

What about dealing with flight in the context of the "projectile motion"
rather than in the context of "fluids"? Too bad the message, posted ten
minutes ago, did not refer to the "less is more" aspect of teaching. It
was actually there, implicitly.
