Any article that "discounts Bernoulli" as having anything to do with
lift is incorrect.


I would have thought so too but I tend to put a fair amount of weight on
what Garrison says when it comes to this sort of thing.

You can use either Newton or Bernoulli to explain lift, but the correct
way to explain it is to explain how both are correct.
In other words, anytime you have lift being created you have a Newton
explanation AND a Bernoulli explanation occurring at the SAME TIME!


According to the article where Bernoulli falls apart is in the assumption
that the air flowing over the top of the wing arrives at the trailing edge
at the same time that the air flowing under the wing does, and since it has
further to travel it must be going faster thereby lowering the pressure
above the wing. The article states that in fact, this is exactly what does
not happen - the air flowing over the wing actually arrives at the trailing
edge after the air flowing under the wing.
