How would you describe fresh clean air?

Describe how an airplane stays in the air include the speed pf air above and below the airplane?

• Answer:

  Airplanes stay in the air by having a curved blunt shaped wing at the front of the wing and a skinny end. By doing this the airplane has more air going over the top of the wing than the bottom, thus creates lift with a vacuum effect. Answer Actually the same amount of air flows over and under the wing. It is the SPEED of the air that produces the lift. When the air speeds up, the pressure drops, thus creating lift from the under-side of the wing. The Speed of the air flow will vary, depending on the type of wing. However, some distance away from the wing and the speed of the air is the same on both sides of the wing.
