Model of a chronological essay

One often wonders how an aircraft gets off the ground and flies. A simple series of aerodynamic processes enable an airplane to take off the ground. First of all, the airplane starts moving down the runway, picking up speed. As it is picking up speed, the air stream moves quickly past its wings. The wings, which are flat on the bottom and bulging on the top, splits the rushing air into two different movements. The air flow under the wings moves slower than that over the wings, building up upward pressure on the bottom surface of the wings. As the plane reaches the top speed on the runway, around 280 kilometers per hour, the pressure of air under the wings becomes strong enough to lift the craft to the air. The plane’s nose looks up, and within seconds the entire aircraft is airborne. The plane has taken off, climbing higher and higher until it reaches the cruising altitude.
