Travelers who must go long distances often prefer airplanes, because planes are much faster than cars. However, planes do not move quickly just to keep airline customers happy. A plane must move forward at a very fast rate in order to take off and stay in the air. The high speed of a moving airplane is caused by the first force of flight, thrust. Thrust is the force that keeps the plane moving forward. It can be created by a powerful jet engine, airplane propellers, or rocket engine.
