Hello all:

Funny, these coincidences. I just received a flier for a talk
to be given here at Fermilab this coming Tuesday (Feb. 17th)
entitled, "The Physics of Flight: It's Newton not Bernoulli".

Hi John!

I suspect that the "Newtonists" are gathering converts at an exponential
rate. This issue is currently popping up in many places. I just received
a message yesterday, from the author of the book NEWTONIAN AERODYNAMICS
(see below.) When I first encountered an article about this in 1987,(1) I
had already been in a couple of teacher/student battles in grade school
over whether wings work because of deflection of air. The issue certainly
didn't start in 1987, but it recently seems to have "hit the fan."
