The essential feature of an airfoil is that it twists the flow of
air as
it
passes (or as the airfoil passes through still air, which is
equivalent,
and
that's how it works in airplanes). The air is accelerated
downward, and
this
engenders an equal and opposite force that is lift.
Nope. That wouldn't explain how wing sections for tailless planes
work. The sections for those curve up towards the trailing edge.
The leading edge produces lift but the trailing edge produces a
_downward_ force to counter the pitching moment. Example section...

Good point.
The porblem with this guy is (and it's just one guy with a handful of
sockpuppets) is that he ses some discrepencies in how bernoulli is
explained and has concluded that it must be incorrect since there is
"disagreement amongst the experts"
A good analogy here would be the eeedjit creationists who grasp at
the straws presented by the minor scuffles occuring within the
evolutionary sciences.

Obviously, pilots AND the airplanes they fly are just plain too
stoopid to fall.
This is it.
A bit like the high rise housing in Monty Python that existed only
because he residents had been hypnotised into believeing they did.
