For every action there is an equal and opposite reaction.
A jet engine is a good example. In odred for the aircraft to move forward (pull ) the engine(s) must deliver enough power in the opposite direction (push)
It is pushing the compressed air out the exhaust to pull the aircraft forward. Well anyway that is how I see it.

Every action has an equal and opposite reaction. That's how rockets get off the ground (only one example). When the rocket fuel burns, the exhaust is forced out the bottom of the rocket (thrust). When there is enough thrust, great enough to overcome the resistance of the rockets weight, the rocket will rise. Even if the rocket is lying on its side it will move away (opposite direction) from the thrust.

A force is a push or a pull upon an object which results from its interaction with another object. Forces result from interactions! , some forces result from contact interactions (normal, frictional, tensional, and applied forces are examples of contact forces) and other forces are the result of action-at-a-distance interactions (gravitational, electrical, and magnetic forces). According to Newton, whenever objects A and B interact with each other, they exert forces upon each other. When you sit in your chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body. There are two forces resulting from this interaction - a force on the chair and a force on your body. These two forces are called action and reaction forces and are the subject of Newton's third law of motion.

What goes up must come down. Without the help of propulsion anyway.
If you punch a wall. The exact shock of the blow to the wall will travel back into your hand. Probably resulting in injury

When you push against an object, the oblect pushes back: inertia.
