How do airplanes fly? Gravity pulls airplanes down.
Airplanes need wings in order to create lift. Lift pushes against gravity. Air creates lift by flowing around the airplane's wings. The plane must gain speed to push the air around the wings. Propellers or jet engines also push or pull the plane forward. This is called thrust.
