jim, airspeed over a wing does not have to faster than
airspeed
below a wing
for a wing to have lift. "bernoulli" sounds conventiently
scientific to
explain lift, but it ain't real.

Because the wing is moving in relation to the air, it is
continuously
"yanking the floor out" from under its current air column,
thereby
generating a continuous lifting force.

Each person can visualise the causes of lift the best way it
works for themselves. I can understand completely what you're
saying, and it's a nice simile. Like all similes, it's
incomplete, but that's irrelevant for sailors and pilots.

Brian Walcott in his 1 Apr post gave an excellent, more thorough
and technical description of the various elements of cause and
effect when creating lift. I would guess he teaches fluid
dynamics.

Jax has been trying to say that you can create lift (low pressure
over a wing) without causing air (in that low pressure) to speed
up, and later, without causing air to move downwards. Rather than
just telling him he's wrong, I've been trying to show him that
his statements are inconsistent with with the laws of physics. So
far he hasn't responded, apart from saying 'nah'.
