  planes fly due to pressure gradient created by airstream (wind) blowing above the plane and that from below the plane. the plane is always made to ensure that the two streams of air will move at different speeds hence difference in pressure which results to an uplift. this is what we call the Bernouli equation.

  Hello Aisher Muser,
  Let me try to explain in simple terms
  If you watch plane taking off or landing, the first thing you notice is the noise of the engines; but its not the engines that make it fly,things can fly without engines, as gliders (planes with no engines), paper planes, and indeed birds
  So, why/how do planes fly?
  A plane’s engines are designed to move it forward at high speed = that makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called LIFT (and the plane takes off) because the LIFT is greater than the weight of the plane and therefore holds holds it in the sky, making it fly
  So it’s the engines that move a plane forward, while the wings move it upward.
