But how exactly do airplanes fly? Flight requires two things: thrust and lift. Thrust is the forward motion provided by a propeller or jet engine. (A propeller, by the way, uses the same principles discussed below to create lift, but it uses that lift to move the plane forward instead ...

fan, or under the rotors of a helicopter, all of which are rotating wings. If the air were coming off the blades at an angle the air would produce a cone rather than a tight column. If a plane were to fly over a very large scale, the scale would register the weight of the plane...
