The droning of the airplane got closer and closer.

When it is far away, it looks like a small bird which flies slowly. However, when it gets closer, it looks really huge, especially when it is flying over your head. Also, I can hear the droning sound of the plane. As the airplane gets closer, the droning sound becomes louder, and it changes from a high tune to a low tune. If the airplane is close enough, I even can see the patten on the airplane. Like " Air Canada" or the maple leaves.
