* Newton's Third Law: Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction.

* Equal and Opposite Force: This means that if the Earth pulls the airplane down with 10,000 Newtons of force, the airplane pulls the Earth upwards with exactly the same 10,000 Newtons of force.

Important Note: While the forces are equal, the effects are very different. The airplane accelerates significantly due to its much smaller mass compared to the Earth, which experiences a negligible acceleration.
