How does a Kite Fly in the sky?

We are enjoy kite flying in the sky but never thought of how does it fly? How does it goes to high while the person who is flying the kite is standing at same position?Lifting force of all kites is produced by deflecting the air downward, the resulting change in momentum producing an upward force. The reason for this is that the air traveling over the top of the curved surface of the kite is going faster than the air passing underneath. Fast-moving air creates less pressure; this means there is more pressure underneath the kite, and this helps to force it upwards.

The air tries to push the kite along. But the string keeps the kite tethered. Since the kite cannot go with the wind flow and the kite is tilted so that the air is deflected downward.
