You know how planes fly; air rubs against the bottom of the wings and slows down, thus pressure increases compared to the top of the wing. Without that friction, the plane stays stuck to the ground. I find it interesting that there are situations in which it’s beneficial to add friction rather than remove it. It’s true with flight, but I’m also thinking of some forms of
