@ceruleanspark Think of it as if a pair of air molecules are hit by the wings and split apart. They want to join back together but because the curve on top is larger the air molecule on top must travel farther. Since the air molecules want to meet at the same time, the one on top would move faster. Because the air is moving faster over the top of the wing it creates and are of low pressure directly above the wing. The air below the wing, then is at relatively high pressure. The way fluids behave on earth is that they always travel from areas of high pressure to areas of low pressure. This causes the air below the wings to push up on the wings trying to get the the low pressure zone. This pushing up on the wings is the force of lift. That is why an aircraft flies.
