Have you ever wondered why planes don’t fall out of the air? You probably had a basic understanding of how speed combined with wings led to flight. Well, that’s it. The key to flight is the shape of the wing. The bottom of the wing is flat, while the top of the wing is curved (like half a water droplet on its side and made out of metal). When the air goes over the curved top of the wing it has to travel farther than the air on the flat bottom. This means that the wind is faster on top of the wing, and thanks to Bernoullli’s Principle, we understand that the faster the wind the lower the pressure. So there is a lot more pressure underneath the wing than above. Voila, we have lift. Also, Newton’s Third Law helps us understand another source of lift. The air moving on the bottom of the wing deflects air downward (the law of reciprocal actions). So, that’s how wings work at the most fundamental level. A lot also depends on how drunk the pilots are.
