- Imagine the jet moves the wing forwards some small distance in some small amount of time.
- Due to the shape of the wing, there is now a temporary vacuum above the wing as air particles have yet to rush in and occupy the space where the wing used to be.
- There is now an unbalanced pressure around the wing sufficient to overcome gravity and give lift.
No Bernoulli, no math, just visualizing a bunch of particles getting pushed around.
If you think about air this way it also becomes obvious why a helium balloon moves in the direction of acceleration inside a car. Car moves forward, air in the rear of the cabin is now squished while the air in front is stretched out as it hasn't caught up to the car yet, pressure gradient sends the balloon forwards.
