Kites are the oldest form of aircraft. They probably originated in China more than 2,000 years ago. During the Han dynasty (206 B.C. to A.D. 220), the Chinese military attached bamboo pipes to the kites. As the kites flew over the enemy, wind passed through the pipes, causing a whistling sound. The noise caused the troops to panic and flee.

What type of kite is used in kite fighting?
Correct Answer
B. Bowed kites
Explanation
The bowed kite is curved on its face to create an angle into the wind, called the dihedral angle. This angle provides stability without the need for a tail. A favorite bowed kite is the two-stick diamond-shaped kite patented in 1891 by an American named William A. Eddy. In India and other countries, fighter kites, which become bowed in the wind, are used in the sport of kite fighting. Participants attach glass-coated lines to their kites and maneuver them in attempts to cut down opponent kites.
