Some researchers hold that approximately 2800 years ago the kite was first invented and popularized in China, where materials ideal for kite building were readily available: silk fabric for sail material, fine, high-tensile-strength silk for flying line, and resilient bamboo for a strong, lightweight framework. Alternatively, kite author Clive Hart and kite expert Tal Streeter hold that kites existed far before that time.Drachen Foundation Journal Fall 2002, page 18. Two lines of evidence: analysis of leaf kiting and some cave drawings The kite was said to be the invention of the famous 5th century BC Chinese philosophers Mozi and Lu Ban. By at least 549 AD paper kites were being flown, as it was recorded in that year a paper kite was used as a message for a rescue mission.Needham, Volume 4, Part 1, 127. Ancient and medieval Chinese sources list other uses of kites for measuring distances, testing the wind, lifting men, signaling, and communication for military operations. The earliest known Chinese kites were flat (not bowed) and often rectangular. Later, tailless kites incorporated a stabilizing bowline. Kites were decorated with mythological motifs and legendary figures; some were fitted with strings and whistles to make musical sounds while flying.(2007). In Encyclopedia Britannica. Retrieved March 29, 2007, from Encyclopedia Britannica Online
After its appearance in China, the kite migrated to Japan, Korea, Thailand, Myanmar (Burma), India, Arabia, and North Africa, then farther south into the Malay Peninsula, Indonesia, and the islands of Oceania as far east as Easter Island. Since kites made of leaves have been flown in Malaya and the South Seas from time immemorial, the kite could also have been invented independently in that region.
One ancient design, the fighter kite, became popular throughout Asia. Most variations, including the fighter kites of India, Thailand and Japan, are small, flat, roughly diamond-shaped kites made of paper, with a tapered bamboo spine and a balanced bow. Flown without tails that would hinder their agility, these highly maneuverable flat kites have a length of cutting line coated with an abrasive attached to the bridle, which is then tied to a light cotton flying line. Although the rules of kite fighting varied from country to country, the basic combat was to maneuver the swift kite in such a way as to cut the opponent\'s flying line.
Kite flying began much later in Europe than in Asia. While unambiguous drawings of kites first appeared in print in the Netherlands and England in the 17th century, pennon-type kites that evolved from military banners dating back to Roman times and earlier were flown during the Middle Ages.
Hang gliders are based on the Rogallo wing, originally marketed as a mylar self-inflating kite named the Flexikite.
During the 18th century tailless bowed kites were still unknown in Europe. Flying flat arch- or pear-shaped kites with tails had become a popular pastime, mostly among children. The first recorded scientific application of a kite took place in 1749 when Alexander Wilson of Scotland used a kite train (two or more kites flown from a common line) as a meteorologic device for measuring temperature variations at different altitudes.
Three years after, in June 1752, in what is the most famous of kite experiments, the American inventor and statesman Benjamin Franklin, with the aid of his son, lofted a flat kite fitted with a pointed wire and silk sail on a hemp line during a thunderstorm. Somehow both father and son avoided electrocution as a metal key attached to the flying line became electrified. Franklin proved that lightning was the natural phenomenon called electricity, not the wrath of the gods. One immediate and practical outcome of the experiment was Franklin\'s invention of the lightning rod.

Kites typically consist of one or more spars to which a paper or fabric sail is attached, although some, such as foil kites, have no spars at all. Classic kites use bamboo, rattan or some other strong but flexible wood for the spars, paper or light fabrics such as silk for the sails, and are flown on string or twine. Modern kites use synthetic materials, such as ripstop nylon or more exotic fabrics for the sails, fiberglass or carbon fiber for the spars and dacron or dyneema for the kite lines.
Kites can be designed with many different shapes, forms, and sizes. They can take the form of flat geometric designs, boxes and other three-dimensional forms, or modern sparless inflatable designs. Kites flown by children are often simple geometric forms (for example, the diamond). In Asia, children fly dried symmetrical leaves on sewing thread and sled-style kites made from sheets of folded writing paper.[citation needed]
Chinese kite designs often emulate flying insects, birds, and other beasts, both real and mythical. The finest Chinese kites are made from split bamboo (usually golden bamboo), covered with silk, and hand painted. On larger kites, clever hinges and latches allow the kite to be disassembled and compactly folded for storage or transport. Cheaper mass-produced kites are often made from printed polyester rather than silk.
Tails are used for some single-line kite designs to keep the kite\'s nose pointing into the wind. Spinners and spinsocks can be attached to the flying line for visual effect. There are rotating wind socks which spin like a turbine. On large display kites these tails, spinners and spinsocks can be 50 feet (15m) long or more.
Modern acrobatic kites use two or four lines to allow fine control of the kite\'s angle to the wind. Traction kites may have an additional line to de-power the kite and quick-release mechanisms to disengage flyer and kite in an emergency.

Kites have been used for military uses in the past for signaling, for delivery of munitions, and for observation, by lifting an observer above the field of battle, and by using kite aerial photography.
Kim Yu-Sin (or Kim Yushin), a Korean general, in 637 C.E. rallied his troops to defeat rebels by kite lofting a burning ball.Linda Sue Park Biography Kites were also used by Admiral Yi of the Joseon (1392-1910) Dynasty of Korea.[citation needed] During the Japanese invasions of Korea (1592-1598), Admiral Yi commanded his navy with kites. His kites had specific markings directing his fleet to perform his order. Admiral Yi was said to have over 300 such kites.[citation needed] The war eventually resulted in a Chinese and Korean victory; the kites played a minor role in the war\'s conclusion.
In more modern times the British navy also used kites to haul human lookouts high into the air to see over the horizon and possibly the enemy ships, for example with the kite developed by Samuel Franklin Cody.Cody kites Barrage kites were used to protect London as well as the Pacific coast of the United States during the last century.Kites On The Winds of War By M.

Kites have been used for scientific purposes, such as Benjamin Franklin\'s famous experiment proving that lightning is electricity. Kites were the precursors to aircraft, and were instrumental in the development of early flying craft. Alexander Graham Bell experimented with very large man-lifting kites, as did the Wright brothers and Lawrence Hargrave. Kites had an historical role in lifting scientific instruments to measure atmospheric conditions for weather forecasting.
Kites can be used for radio purposes, by kites carrying antennas for MF, LF or VLF-transmitters. This method was used for the reception station of the first transatlantic transmission by Marconi. Captive balloons may be more convenient for such experiments, because kite carried antennas require a lot of wind, which may be not always possible with heavy equipment and a ground conductor. It must be taken into account during experiments, that a conductor carried by a kite can lead to a high voltage toward ground, which can endanger people and equipment, if suitable precautions (grounding through resistors or a parallel resonant-circuit tuned to transmission frequency) are not taken.
Kites can be used to carry light effects such as lightsticks or battery powered lights.
Kites can be used to pull people and vehicles downwind. Efficient foil-type kites such as power kites can also be used to sail upwind under the same principles as used by other sailing craft, provided that lateral forces on the ground or in the water are redirected as with the keels, center boards, wheels and ice blades of traditional sailing craft. In the last two decades several kite sailing sports have become popular, such as kite buggying and kite surfing.
Kite sailing opens several possibilities not available in traditional sailing:
The German company SkySails has developed ship-pulling kites as a supplemental power source for cargo ships, first tested in January 2008 on the ship MS_Beluga_Skysails.Andrew Revkin. It\'s a freighter, it\'s a sailboat - no it\'s both. Trials on this 55m ship have shown that, in favorable winds, the kite reduces fuel consumption by up to 30%. This system is planned to be in full commercial production late 2008. Skysail ship pulling system Kites are available as an auxiliary sail or emergency spinnaker for sailing boats. Self-launching Parafoil kites are attached to the mast.[citation needed]MS Beluga Skysails is the world\'s first commercial container cargo ship partially powered by a giant computer-controlled kite (160sq. m. or 1,722 sq ft.). The kite could reduce fuel consumption by 20%. It was launched on 17 December 2007 and was set to leave the northern German port of Bremerhaven to Guanta, Venezuela on January 22, 2008. Stephan Wrage, managing director of SkySails GmbH announced: "During the next few months we will finally be able to prove that our technology works in practice and significantly reduces fuel consumption and emissions." Verena Frank, project manager at Beluga Shipping GmbH, SkySails GmbH\'s partner further stated that "the project\'s core concept was using wind energy as auxiliary propulsion power and using wind as a free of charge energy".BBC NEWS, Kite to pull ship across Atlantic

Kite festivals are a popular form of entertainment throughout the world. They include small local events, traditional festivals which have been held for hundreds of years and major International Festivals which bring in kite flyers from overseas to display their unique art kites and demonstrate the latest technical kites.
Kite flying is very popular in many Asian countries, where it often takes the form of \'kite fighting\', in which kite fighters try to snag each other\'s kites or cut other kites down. Fighter kites are usually small, flat, flattened diamond-shaped kites made of paper and bamboo. Tails were left off of the fighter kites so that agility and maneuverability were not compromised. The usual goal of a \'kite fighter\' is to maneuver his/her kite to cut the opponent\'s string.Kite.(2007) Encyclopedia Britannica Online In Afghanistan this is known as Gudiparan Bazi. Some kite fighters pass their strings through a mixture of ground glass powder and glue. The resulting strings are very abrasive and can sever the competitor\'s strings. The modernization of the sport of \'kite fighting\' comes with newer technology, as canny arms dealers begin importing a flexible razor sharp wire from China, rather than the old, nylon fishing line used for kite string.The Kite Maker. (2007) Time Magazine. However, this practice is dangerous since the abrasive strings can also injure people. During the Taliban rule in Afghanistan, kite flying was banned, among various other recreations.
In Korea kites were usually flown to make a wish or wish the person flying the kite good luck. The kites were usually flown on festive days and national holidays. In countrysides children used to take part in a fun battle where a person tried to disconnect the main bit of a kite of their opponent when the opponent tried to disconnect theirs. To disconnect an opponent\'s kite one would have to have a strong, steel-like thread to attach the main bit of a kite to the traditional Korean wooden reel, called Earl Leil
In Vietnam, kite flown by adults are "tail-less". Instead small flutes are attached allowing the wind to "hum" a musical tune. There are other forms of sound-making kites. In Bali, large bows are attached to the front of the kites to make a deep throbbing vibration, and in Malaysia row of gourds with sound-slots are use to create a whistle as the kite flies.
The Indian festival of Makar Sankranti is devoted to kite fighting in some states. This spring festival is celebrated every January 14 (or January 15 on leap years),from this year and onward festival will be celebrated on 15th of January, with millions of people flying kites all over northern India. The states of Bihar, Jharkhand, Gujarat, some part of West Bengal, Rajasthan , and the cities of Ahmedabad, Jaipur,Dhanbad and Hyderabad are particularly notable for their kite fighting festivals. Highly maneuverable single-string paper and bamboo kites are flown from the rooftops while using line friction in an attempt to cut each other\'s kite lines, either by letting the line loose at high speed or by pulling the line in a fast and repeated manner. The activity is not without risk as the line is treated to be abrasive and flyers can, and occasionally do, fall from the rooftops. In some Indian cities kite flying/fighting is an important part of other celebrations, including Republic Day, Independence Day, Raksha Bandhan, and Janmashtami.
Hyderabad is one city in India where Kite Flying is taken as a serious game. Kite flying starts a month before the official Kite flying Festival (Sankranthi). The thread with what people fly kites in Hyderabad is designated a \'Manjaa\' in local terms and this thread aids in cutting others Kites in sky. The sharper and stronger the thread, the more shall be the chances of downing others Kites. Even the Kite and Thread vendors make a great deal of money during this festival. Millions of Kites can be seen on this day in Hyderabed, each one fighting for their own survival. People usually spend all day on the terrace with their families, flying kites during this memorable day.

In Pakistan, kite flying is a ritual for the spring festival known as Basant. However, kite flying is currently banned as some kite fliers engage in kite battles by coating their strings with glass or shards of metal, leading to injuries and death. Kite fighting is a very popular sport in Pakistan, mainly centered in Lahore people spend thousands of dollars in preparing different types of kites and threads best suited to battle. The kites that are manufactured for battling are very different from the conventional kites as they are especially designed and made for this purpose. Kup, Patang, Guda, Nakhlaoo, etc are some of the kites used in the battle and they vary in balance, weight and speed through the air. Threads for kite battling are manufactured using especial glues, chemicals and crushed glass and are numbered based on their ability to cut other threads and to handle kite\'s weight. It is a very popular social event in Pakistan that happens once a year.
Weifang (Shandong, China) promotes itself as the Kite Capital of the World. It is home to the largest kite museum in the world, which has a display area of 8100 m². Weifang hosts an annual International Kite Festival on the large salt flats south of the city. There are several kite museums in Japan and others in England, Malaysia, Indonesia, Taiwan, Thailand and the USA.
In Greece, flying kites is a tradition for Clean Monday, the first day of Lent.
In Guyana, on Easter Weekend thousands turn out for mass kite flying. In the capital city of Georgetown the massive sea wall protecting the city from the Atlantic ocean is filled with throngs of families picnicking and flying kites of all shapes and colors. Many participate in kite flying competitions. In certain South American countries the verb Kitar is used to describe the art of kite-flying.
There are safety issues involved in kite-flying, more so with power kites. Kite lines can strike and tangle on electrical power lines, causing power blackouts and running the risk of electrocuting the kite flier. Wet kite lines or wire can act as a conductor for static electricity and lightning when the weather is stormy. Kites with large surface areas or powerful lift can lift the kite flier off the ground or drag them into stationary objects. In urban areas there is usually a ceiling on how high a kite can be flown, to prevent the kite and line infringing on the airspace of helicopters and light aircraft. In Asia, specially in the Indian subcontinent the twine is coated with powdered glass to cut opponent\'s lines and these deadly strings known as Manja are reported to kill number of pedestrians or motorcyclists each year all over the region.Kite deaths mar Pakistan festivalPakistan tackles killer kites By Shahid Malik
