Answer:
There are four forces that act on the plane while it's in the air: thrust, drag, lift and gravity. The thrust is generated by the jet engines, and this helps the plane to propel forwards, whereas the lift force acts on the plane wings and allows it to move upwards, and also to maintain its altitude.That's how airplanes stay in air.
