How do airplanes stay in the air

Airplanes stay in the air due to the lift force created by their wings. As the airplane moves forward, air flows over and under the wings. The shape of the wings is designed so that air moves faster over the top of the wing and slower underneath. This difference in air pressure creates an upward force, known as lift, which counteracts the force of gravity and keeps the airplane in the air.
